All-terrain vehicle fatalities on paved roads, unpaved roads, and off-road: Evidence for informed roadway safety warnings and legislation

Rural adolescent attitudes and use of helmets while riding ATVs, motorcycles and dirt bikes

BACKGROUND

Head injuries are the most common cause of death in some motorized vehicles for which helmet use can significantly decrease the risk. Our objective was to determine rural adolescents' attitudes regarding helmets and their use while riding ATVs, motorcycles and dirt bikes.

METHODS

A convenience sample of 2022 Iowa FFA (formerly Future Farmers of America) Leadership Conference attendees were surveyed. After compilation, data were imported into the statistical program, R ( https://www.R-project.org/ ). Descriptive statistics, contingency table, logistic regression and non-parametric alternatives to ANOVA analyses were performed.

RESULTS

1331 adolescents (13-18 years) participated. One half lived on a farm, 21% lived in the country/not on a farm and 28% were from towns. Nearly two-thirds (65%) owned an ATV with 77% of all having ridden one in the past year. Farm residents had the highest ATV ownership (78%) and having ridden (80%) proportions, both p < 0.001. Overall, ownership and ridership for motorcycles (22% and 30%, respectively) and dirt bikes (29% and 39%, respectively) was significantly less than ATVs, all p < 0.001. Of ATV riders, those living on farms or in the country/not on a farm rode them more frequently than those from towns, p < 0.001. Higher percentages always/mostly wore helmets when riding dirt bikes (51%) and motorcycles (57%) relative to ATVs (21%), p < 0.001. Those from farms had lower proportions wearing helmets versus those living elsewhere for all vehicles. Helmet use importance ratings (1-10, 10 high) were not different for motorcycles (mean 8.6, median 10) and dirt bikes (mean 8.3, median 10), but much lower for ATVs (mean 6.1, median 6). Females, non-owners, and helmet law supporters all had higher helmet use importance ratings. Males, those from farms, and owners and riders of the vehicles all had lower proportions that supported helmet laws. Support for helmet laws was significantly lower for ATVs (30.7%) than dirt bikes (56.3%) or motorcycles (72.3%), both p < 0.001. Those whose families had strict ATV "No Helmet, No Riding" rules had much higher helmet use and helmet importance ratings.

CONCLUSIONS

Our study indicates that the safety culture surrounding helmet use is relatively poor among rural adolescents, especially on farms, and deserves targeted interventions.

The association between county ordinances allowing off-road vehicles on public roads and crash rates

BACKGROUND

Legislative bodies across the country have increasingly allowed off-road vehicles (ORVs) including all-terrain vehicles (ATVs) and utility task vehicles (UTVs) on public roads, an environment for which they are not designed. In 2004, Iowa gave individual counties the discretion to pass ordinances allowing ORVs on public roadways. The objective of this study was to evaluate the relationship between the passage of ORV ordinances and ORV crash rates, especially on public roads.

METHODS

An Iowa ORV roadway ordinance database and an Iowa ORV crash database (2002-2018) for all 99 counties were compiled. Crashes for which county location could not be determined were excluded. Utilizing a zero-inflated Poisson model, correcting for background crash frequency trends and population, investigators compared the relative rates of crashes after ordinance passage to time points before ordinance implementation and to counties without such ordinances. Sub-analyses, including that focused on more recent years (2008-2018), were also performed.

RESULTS

Forty-five county ORV roadway ordinances went into effect between 2011 and 2018 and 2,347 crashes (69%) met inclusion criteria. Adjusted for year, there was a 58% greater ORV crash rate in counties after passing an ORV roadway ordinance (incidence rate ratio (IRR) 1.58, 95% CI 1.32-1.90). Roadway crashes (n = 834) increased 48% after ordinance passage (IRR 1.48, 95% CI 1.14-1.94). This roadway crash association remained statistically significant when analysis was limited to the years 2008-2018 (IRR 1.39, CI 1.06-1.83, n = 544); to ATV crashes only (IRR 1.70, CI 1.20-2.40, n = 683); and to ATV crashes excluding counties with UTV-only ordinances (IRR 1.74, CI 1.40-2.15, n = 2,011).

CONCLUSIONS

ORV roadway and total crashes increased significantly after implementation of county ordinances allowing ORVs on public roadways and when compared to counties without such ordinances. It is likely that these increased crashes have resulted in more injuries and possibly deaths. Results from this study may help inform policymakers as they consider legislation regarding ORV usage on public roads.

Predicting behavioral intentions for unsafe off-highway vehicle use

INTRODUCTION

Hundreds of adults are killed or injured each year while operating off-highway vehicles. Four common risk-taking behaviors were identified on off-highway vehicles in the literature and examined intention to engage in such behaviors within the context of the Theory of Planned Behavior.

METHOD

One hundred and sixty-one adults completed measures of experience on off-highway vehicles and injury exposure followed by a self-report created according to the predictive structure of the Theory of Planned Behavior. Behavioral intentions to engage in the four common injury risk behaviors on off-highway vehicles were predicted.

RESULTS

Similar to research on other risk behaviors, perceived behavioral control and attitudes emerged as consistently significant predictors. Subjective norms, the number of vehicles operated, and injury exposure showed varying relationships to the four injury risk behaviors. Results are discussed in the context of similar studies, intrapersonal predictors of injury risk behaviors, and with regard to implications for injury prevention efforts.

Recreational off-highway vehicle exposure, safety behaviors and crash experiences among adolescents

BACKGROUND

Recreational off-highway vehicles (ROVs), often called utility task vehicles (UTVs), are designed to be driven by those ≥ 16 years and manufacturers recommend passengers be at least 12 years old. This study's objective was to determine Iowa adolescents' exposure to ROVs, riders' use of restraint devices, and crash prevalence.

METHODS

Adolescents participating in the Safety Tips for ATV Riders (STARs) program at their schools were anonymously surveyed by the Iowa Off-Road Vehicle Safety Task Force from Fall 2014-Fall 2019. Frequency, bivariate (chi square and Fisher's exact test) and logistic regression analyses were performed using SAS software, V.9.4.

RESULTS

A total of 4,023 students (9-18 years) from 18 school districts participated. Overall, 68% reported having ridden in an ROV. The proportions having ridden an ROV by where participants lived were farm (85%) > country/not farm (73%) > town (60%), p < 0.0001. Of those asked additional ROV questions (n = 2152), 39% of ROV riders reported riding at least weekly in the previous 12 months. Of those riding ROVs in the past year, 29% reported having at least one crash. Males and respondents living on farms had higher percentages reporting crashes, as compared to females (31% vs. 24%, p = 0.005) and those living elsewhere (35% vs. 24%, p = 0.0003). Thirty-seven percent of ROV riders never or almost never wore their seatbelt. Seatbelt use was inversely proportional to age, p < 0.001. A higher proportion of females reported always or almost always wearing a seat belt (42% vs. 36%, p = 0.0016). Percentages never or almost never wearing seatbelts by residence were farm (47%) > country/not farm (38%) > town (32%), p = 0.0005. Almost daily riders and those reporting having been in a crash were both 1.7 times more likely to never or almost never wear a seatbelt as compared to infrequent riders and those without a crash, respectively.

CONCLUSIONS

Iowa adolescents frequently ride ROVs and often without a seatbelt, putting them at greater risk for serious injury or death in a crash. Almost 30% of riders reported an ROV-related crash in the past year. Our study identified a high-risk population that could be targeted for ROV safety education and other injury prevention efforts.

American Academy of Pediatrics Recommendations for the Prevention of Pediatric ATV-Related Deaths and Injuries

Since all-terrain vehicles (ATVs) were introduced in the mid-1970s, regulatory agencies, injury prevention researchers, and pediatricians have documented their dangers to youth. Major risk factors, crash mechanisms, and injury patterns for children and adolescents have been well characterized. Despite this knowledge, preventing pediatric ATV-related deaths and injuries has proven difficult and has had limited success. This policy statement broadly summarizes key background information and provides detailed recommendations based on best practices. These recommendations are designed to provide all stakeholders with strategies that can be used to reduce the number of pediatric deaths and injuries resulting from youth riding on ATVs.

A Comprehensive Report on All-Terrain Vehicles and Youth: Continuing Challenges for Injury Prevention

All-terrain vehicles (ATVs) represent a serious and ongoing public health and safety concern for children and adolescents. Survey studies indicate that high proportions of youth ride ATVs in both rural and nonrural populations. The significant human and economic costs of pediatric ATV-related deaths and injuries result from a number of major risk factors that are highly common in pediatric ATV crashes: operating adult-size vehicles, riding with or as passengers, lack of protective equipment, and riding on public roads. Other less well-studied but potentially significant risk factors are speed, riding at night, alcohol use among older teenagers, and lack of training and supervision. Although potentially safer than adult ATVs, youth models present a number of safety concerns that have not been addressed with rigorous study. The most common ATV crash mechanism is a noncollision event-for example, a rollover. Common injury mechanisms include ejection from the vehicle, resulting in extremity and head injuries, and being pinned or crushed by the vehicle with resulting multiorgan trauma and/or compression asphyxia. Traumatic brain injury and multisystem trauma are the 2 most common causes of death and disabling injury. Taken together, a large multidecade body of evidence is the basis for the American Academy of Pediatrics policy statement recommendation that no child younger than 16 years of age ride on an ATV. Because children continue to be allowed to ride these vehicles, however, efforts to prevent pediatric ATV-related deaths and injuries require multipronged strategies, including education of both youth and parents, safety-based engineering, and enforcement of evidence-based safety laws.

The dark side of nighttime all-terrain vehicle use

BACKGROUND

Driving at night is considered a risk factor for all-terrain vehicle (ATV) crashes and injuries but few studies have addressed this issue. Our objective was to compare daytime and nighttime ATV crashes to better understand the potential risk factors associated with riding at night.

METHODS

A retrospective study was conducted on Iowa ATV-related crashes and injuries from January 1, 2002 through December 31, 2019 using four statewide datasets: the Iowa Department of Transportation (2002-2019), the Iowa Department of Natural Resources (2002-2019), the Iowa State Trauma Registry (2002-2018) and Iowa newspaper clippings (2009-2019). A standardized coding system was developed, and matching records were identified using Link Plus®. Descriptive (frequencies) and bivariate (chi-square, Fisher's exact test) analyses were performed using VassarStats (Statistical Computation Website).

RESULTS

Among crash victims where light conditions were documented (2125/3752, 57%), about one-quarter (485/2125, 23%) were injured at night. Nighttime crash victims were less likely youth (14% vs. 30%, p < 0.0001), less likely to be wearing helmets (11% vs. 18%, p = 0.003), and less frequently involved in motor vehicle crashes (7% vs. 14%, p < 0.0001) as compared to daytime victims. Nighttime victims were also more likely to be passengers (22% vs. 15%, p = 0.002), to test positive for alcohol (44% vs. 13% in adults, p < 0.0001), and to be injured on a roadway (53% vs. 45%, p = 0.007) and on weekends (76% vs. 63%, p < 0.0001). Numerous differences between daytime and nighttime characteristics were observed for males, females, and adults, whereas most characteristics were similar for youth. The severity of injuries and proportion of fatalities were similar among daytime and nighttime crash victims.

CONCLUSIONS

Nighttime crash victims, particularly adults, were characterized by more frequent risky behaviors like carrying passengers, roadway riding, alcohol use, and lack of helmets. Whereas the frequency of risky behaviors among youth was similar for daytime and nighttime crashes, these behaviors put children at potential risk for injury. Multi-factorial, targeted injury prevention strategies are needed, including improved vehicle design, education about the dangers of nighttime operation, and passage and enforcement of ATV safety laws. Particularly relevant to our study are laws that prohibit nighttime riding.

Nonfatal Agricultural Injuries Treated in Emergency Departments: 2015-2019

Utilizing emergency department admissions to estimate and describe agricultural injuries in the United States (U.S.) provides a unique view of one of the country's most dangerous occupations. This study characterizes and provides nationally representative estimates of persons with non-fatal agricultural-related injuries treated in emergency departments in the U.S.We conducted a cross-sectional study using U.S. Consumer Product Safety Commission, National Electronic Injury Surveillance System (NEISS) data for patients treated in emergency departments from January 1, 2015 to December 31, 2019. We queried all cases in the NEISS database using the location code "farm" and with a narrative search using relevant key words.An estimated 62,079 people were treated in an emergency department for agricultural related injuries. The mean age estimate in this population was 39 years-old, with ages ranging from 1 to 95. Almost two-thirds of patients were male, and almost 80% were white. Approximately 30% and 22% of those injured were youth and elderly patients, respectively. The majority of injuries occurred from April through September. The most common injury was fracture, followed by open wound or amputation. There were significant differences between the body parts injured in youth versus adult patients. The primary source of injury was in the vehicles category, with tractors being the dominant vehicle type.Agricultural vehicles remain a major source of injuries that require treatment in emergency departments. Previous methods of quantifying severe ag-related injuries were limited; our research utilized NEISS data to portray injury statistics more accurately.

Spatio-Temporal Patterns and Consequences of Road Kills: A Review

Simple Summary

Road kill continues to be a challenge in the 21st century. Numerous studies have sought to explain the causes and risks of animal-vehicle collisions that result in road kills, and how best to mitigate these events. This review evaluates the relevant literature on road kills, in order to determine how to effectively address them. Identifying methodologies and sources used in previous studies, how mortalities are normally recorded and reported was determined. Previous literature has suggested that spatial proximity, road infrastructure, traffic volume and velocity, driver awareness, landscape, climate and weather conditions, and animal behavior are the primary factors contributing to the spatio-temporal patterns of road kills. Important socioeconomic and environmental impacts of animal-vehicle collisions that result in road kills were also identified. Current mitigation measures for addressing road kills were examined from previous studies; including road management and wildlife crossing structures. Shortcomings to strategies and methodologies for addressing animal-vehicle collisions were subsequently assessed. Thereafter, the paper analysed geospatial technologies that have been utilised inroad kill studies. This review recommends focusing an all road kills in an area, using larger study locations, taking timelier observations, the increased use of citizen science, more research on nighttime driving speeds, and popularising effective road kill apps.

Abstract

The development and expansion of road networks have profoundly impacted the natural landscape and various life forms. Animals are affected by these roads in a myriad of ways, none as devastating as road mortalities. This article reviews the literature on the magnitude, spatiotemporal patterns, factors, and consequences of Animal-Vehicle Collisions (AVCs) and the subsequent road kills. Furthermore, the review paper briefly outlines the relationship between roads and animals in the surrounding landscape and later examines the nature and impacts of AVCs. This article evaluates the statistics on the number of road kills and a critical analysis of the spatiotemporal patterns of these mortalities is also evaluated. Subsequently, the review paper examines current mitigation measures and the challenges impeding their success. The paper then concludes with an evaluation of geospatial tools (GIS) and other technologies used in road kill studies. The relevant findings of this paper are that, (1) factors influencing road kill patterns interact with one another; (2) AVCs have serious environmental, economic and social consequences; (3) road kill mitigation strategies suffer several challenges hindering their success; and (4) specific geospatial tools and other technologies have been utilised in assessing AVC road kill patterns. The review, therefore, recommends including overall road kill clusters of all animals in mortality surveys, increasing the spatial coverage of road kill observations, consistent surveying, sufficient research on nighttime driving distances and speed, utilising citizen science in all road mortality studies and incorporating GIS into all apps used for recording road kills. An increased sufficiency in road kill data coupled with improved technologies can enable more effective mitigation strategies to prevent AVCs.

Agricultural All-Terrain Vehicle Safety: Hazard Control Methods Using the Haddon Matrix

All-terrain vehicle (ATV) crashes are one of the leading causes of death and injury in agriculture across the United States. Use of ATVs is highly prevalent in rural areas and has seen an increase in their application for a variety of agricultural work tasks. Empirical research on the use of these vehicles for agricultural tasks and associated injuries is limited, especially in the United States. Moreover, little is known about the risk factors associated with ATV-related injuries while doing farm work. A comprehensive review was conducted to evaluate the current injury burden of ATV use in agriculture, the need for future research, and possible solutions related to agricultural ATV safety. Potential injury prevention approaches are evaluated based on the hierarchy of control, including elimination or substitution (using side-by-side vehicles instead of ATVs or modifying ATV design), engineering control (operator protection devices), administrative authority (regulations and standards in the United States and around the world), training, and use of personal protective equipment. In addition, vehicle nomenclature, risk factors, and crash mechanisms are reviewed. Recommendations to decrease the likelihood of ATV crashes and injuries are provided.

Nonfatal All-Terrain Vehicle-Related Head and Neck Injuries to Children Treated in US Emergency Departments

This study investigates children <18 years old with nonfatal all-terrain vehicle (ATV)-related head and neck injuries treated in United States emergency departments by analyzing data from the National Electronic Injury Surveillance System from 1990 to 2014. An estimated 279 391 children received emergency treatment during the 25-year study period. The number of injuries remained relatively constant from 1990 to 1997, increased by 142.9% from 1997 to 2007, and then decreased by 37.4% from 2007 to 2014. The most common diagnoses were concussion/closed head injury (32.6%) and fracture (32.6%); 15.4% of children were admitted. The most common injury mechanisms include ejection (30.0%), crash (18.8%), and rollover (15.8%). Patients who were injured on a street/highway were 1.49 times (95% confidence interval = 1.11-1.99) more likely to be admitted than patients injured at other locations. Although the number of nonfatal ATV-related head and neck injuries decreased during the latter part of the study period, they remain common and can have serious medical outcomes.

Recreational off-highway vehicle crashes resulting in victims being treated at a regional trauma center: mechanisms and contributing factors

BACKGROUND

Recreational off-highway vehicles (ROVs) have become increasingly popular in recent years; however, crash epidemiology is not well described. ROVs travel at least 30 mph, and unlike all-terrain vehicles, have a rollover protective structure (ROPS) and seat belts or a harness system for occupants. This study's objective was to evaluate the demographics, mechanisms, injuries, and associated risk factors of ROV crashes.

METHODS

A retrospective chart review was performed for patients of all ages with ROV-related injuries presenting to a Level 1 trauma center from 2004 to 2017. Cases were identified by ICD-9/10 codes and narrative searches. Person- and crash-related variables were examined in relation to injury outcomes including body area injured, injury severity score, and disposition (e.g. hospitalization, intensive care unit admission). Descriptive, bivariate (chi-square, Fishers exact test), and linear regression analyses were performed.

RESULTS

Seventy-two patients with ROV-related injuries were identified. The number of injured patients increased over the study period (p < 0.01). Patients were 49% youth < 16 years old, 63% males, and 99% Caucasian. Half of the injured (51%) were passengers, with a higher proportion of youth being passengers (70%) as compared to adults (35%) (p < 0.01). Nearly one-third (30%) of crash victims < 16 years old were ROV drivers. Twenty-nine percent of all crashes occurred on roadways. Almost 40% of injured adults crashed at night, while all youth were injured during the day (p < 0.01). The primary crash mechanism was a rollover (67%). Only one patient was documented as being helmeted, and approximately one-fourth (24%) sustained head injuries and/or loss of consciousness. Other documented injuries included those to the face (20%), chest (22%), abdomen (11%), extremities (58%), and skin (51%). Over 90% of narratives were consistent with victims being unrestrained. Nearly three-fourths (74%) of victims were hospitalized and 26% required ICU care, one-half (53%) of these being children.

CONCLUSIONS

Although ROVs have ROPs, lack of helmet and safety belt use are reducing their benefit. Youth are a large proportion of those injured in ROV crashes, often while driving despite vehicle operation recommended only for those ≥16 years old. Increased public education is needed regarding proper safety measures while operating and riding ROVs.

Assessing the Emergent Public Health Concern of All-Terrain Vehicle Injuries in Rural and Agricultural Environments: Initial Review of Available National Datasets in the United States

Background

Injuries related to the operation of off-road vehicles (ORVs), including all-terrain vehicles (ATVs), continue to be a significant public health concern, especially in rural and agricultural environments. In the United States alone, ATVs have played a role in thousands of fatalities and millions of injuries in the recent decades. However, no known centralized federal surveillance system consistently captures these data. Traditional injury data sources include surveys, police reports, trauma registries, emergency department data, newspaper and online media reports, and state and federal agency databases.

Objective

The objectives of this study paper were to (1) identify published articles on ORV-related injuries and deaths that used large databases and determine the types of datasets that were used, (2) examine and describe several national US-based surveillance systems that capture ORV-related injuries and fatalities, and (3) promote and provide support for the establishment of a federally-funded agricultural injury surveillance system.

Methods

In this study, we examined several national United States–based injury datasets, including the web-based AgInjuryNews, the Fatality Analysis Reporting System, databases compiled by the US Consumer Product Safety Commission, and the National Fatality Review Case Reporting System.

Results

Our review found that these data sources cannot provide a complete picture of the incidents or the circumstantial details needed to effectively inform ORV injury prevention efforts. This is particularly true with regard to ORV-related injuries in agricultural production.

Conclusions

We encourage the establishment of a federally funded national agricultural injury surveillance system. However, in lieu of this, use of multiple data sources will be necessary to provide a more complete picture of ORV- and other agriculture-related injuries and fatalities.

Injuries among all-terrain vehicle users: a population-based study

Background

The use of off-road vehicles such as all-terrain vehicles (ATVs) and recreational off-highway vehicles has increased in recent years. A higher percentage of patients hospitalised following ATV crashes suffered severe injuries, compared with those hospitalised following other MVCs.

Objective

To identify incidence of ATV-related injury and characterise groups with higher prevalence.

Methods

A retrospective study of the Israel National Trauma Registry data between years 2008 and 2016. ATV crash victims were compared with other types of MVC casualties according to demographics, injuries and hospital resource utilisation. Identifying groups with greater prevalence for severe injuries caused by ATV crashes was conducted using logistic regressions.

Results

An increase of 49% in the number of casualties hospitalised following an ATV crash was observed between 2013 and 2016. Non-Jews, males and users 15–29 years old were hospitalised at a higher rate compared with their proportion in the population. ATV crash casualties were more severely injured compared with other MVC casualties (22% vs 14%), had longer hospital length of stay (8+ days) (25% vs 18%), more admissions to intensive care units (16% vs 10%) and underwent more surgery (39% vs 26%, respectively). Males, non-Jews and casualties who did not wear a helmet were about two times more likely to suffer from severe head injury (95% CI 1.20 to 3.60, 1.41 to 2.75 and 1.27 to 4.73, respectively).

Conclusions

An increase in ATV-related casualties was observed. A customised safety intervention programme is needed that targets demographic groups identified with higher injury incidence. Awareness of legislated and common sense ATV safety practices, specifically helmet use, should be raised.

The Effect of All-Terrain Vehicle Crash Location on Emergency Medical Services Time Intervals

Over 100,000 all-terrain vehicle (ATV)-related injuries are evaluated in U.S. emergency departments each year. In this study, we analyzed the time intervals for emergency medical services (EMS) providers responding to ATV crashes in different location types. Data from the Iowa State Trauma Registry and a statewide ATV crash/injury database was matched with Iowa EMS Registry records from 2004–2014. Ground ambulance responses to 270 ATV crashes were identified, and response characteristics and time intervals were analyzed. Off-road crashes had a longer median patient access interval (p < 0.001) and total on scene interval (p = 0.002) than roadway crashes. Crashes in remote locations had a longer median patient access interval (p < 0.001) and total on scene interval (p < 0.001), but also a longer median on scene with patient interval (p = 0.004) than crashes in accessible locations. Fifteen percent of remote patient access times were >6 min as compared to 3% of accessible crashes (p = 0.0004). There were no differences in en route to scene or en route to hospital time. Comparisons by location type showed no differences in injury severity score or number of total procedures performed. We concluded that responding EMS providers had an increased length of time to get to the patient after arriving on scene for off-road and remote ATV crashes relative to roadway and accessible location crashes, respectively.

Road traffic injuries in China from 2007 to 2016: the epidemiological characteristics, trends and influencing factors

Background

Road traffic accidents are one of the serious disasters that cause public injury, fatality and great economic loss. They are a growing public health problem around the world.

Objectives

The aim of this study was to determine epidemiological characteristics, tendency and possible influencing factors of road traffic injuries (RTIs) in China, so as to give target suggestions on preventative measures.

Methods

Road traffic accident data were obtained from National Bureau of Statistics of China and Ministry of Transport of the People’s Republic of China. Descriptive statistic such as RTIs frequency, trends of different accident types from 2007 to 2016; the RTIs difference between different regions and road surfaces were compared; and the possible influencing factors of RTIs were also explored.

Results

Over the past decade, with the mileage of constructed highway increased, the frequency of road traffic accidents have declined substantially in China, and the death toll from road traffic accidents with motor vehicles has declined from 2007 to 2015, Conversely, the number of deaths from non-motor vehicle accidents has risen rapidly since 2012. Our study showed that the traffic accident related mortality in Guizhou province was different from the level of the whole nation, and the Eastern, Central and Western areas of China were all significantly different (P < 0.001). Linear regression suggested a significant affected of gross domestic product (GDP)-per-capita, education level, the number of health institutions, populations, and car ownership status on traffic accident death tolls (P < 0.001). Moreover, cement concrete pavement roads were associated with the highest occurrence rates of RTI, and RTIs was statistically significant (P < 0.001) on different road surfaces.

Conclusion

Even though the frequency of road traffic accidents has declined, RTIs remain an urgent public health problem in China. Thus, the government should give some target preventative measures to reduce RTIs, aiming at different regions, the increasing trend of the death toll related to non-motor vehicles and the highest occurrence on cement concrete pavement roads.

Enforcement of Off-Road Vehicle Laws in Iowa

Safety laws are among the most successful means of reducing injuries, but their effectiveness is strongly influenced by the level of enforcement. To characterize enforcement of off-road vehicle (ORV) laws statewide, analyses of citations were performed using Iowa Court Information System data. From 2005–2015, 5173 individuals were charged with 5643 citations issued. Citations averaged <5/county/year, decreased dramatically over time, and varied by county when normalized to registered all-terrain vehicles (ATVs). Over 90% of operators cited were male and Caucasian. One-fifth were <18 years old. The top five violations were: operation on a highway/snowmobile trail (51%), registration/identification number not documented/displayed (19%), prohibited use in a park/preserve (5.5%), and operation with more persons than the vehicle is designed to carry (4.4%). The Department of Natural Resources issued the highest percentage of citations, followed in decreasing order by Sheriff, Police, State Patrol, and Conservation officers. Significant differences were identified when citations were compared by sex, age, race, enforcement agency, disposition (guilty vs. not guilty), and when comparing counties with or without an ORV park. These characteristics suggest limited and variable enforcement of laws statewide that may reduce their potential to prevent deaths and injuries, and that improved strategies to support ORV law enforcement are needed.

Pediatric and adolescent injury in all-terrain vehicles

All-terrain vehicles (ATVs) remain a significant source of death and injury among youth. The purpose of this review is to provide an overview of the scope of the problem, the risk factors involved, crash-related outcomes and costs, and injury prevention strategies. There are currently more than 100 pediatric ATV-related fatalities each year and over 30,000 emergency department visits, with a potential annual cost for deaths and injuries approaching $1 billion. Major risk factors include lack of training, operating adult-size ATVs, riding as or carrying passengers, riding on the road, and not wearing a helmet. Extremity injuries are highly common, and the leading causes of death include brain injuries and multi-organ trauma. The latter increasingly involves being crushed by or pinned under the ATV. Reducing ATV-related deaths and injuries will require multiple strategies that integrate approaches from education, engineering, and evidence-based safety laws and their enforcement.

Trends in All-terrain Vehicle Injuries From 2000 to 2015 and the Effect of Targeted Public Safety Campaigns

INTRODUCTION

All-terrain vehicles (ATVs) represent a notable portion of orthopaedic injuries presenting to emergency departments (EDs) in the United States. Public awareness campaigns have targeted these injuries, and this study sought to examine the effect of the 2007 American Academy of Orthopaedic Surgeons public safety campaign on ATV use.

METHODS

The United States Consumer Product Safety Commission National Electronic Injury Surveillance System (NEISS) was used to obtain national estimates of ATV and dirt bike injuries for the years 2000 to 2015. ED visits resulting from ATV injuries and dirt bike injuries were identified using NEISS product codes (ie, 3285-3287, 3296, and 5036). Patient demographics, injury-related data, and total annual case numbers were estimated. Chi-square tests and logistic regression were used for comparative analyses as appropriate. All statistical analyses were performed using SAS statistical software v.9.4 (SAS Institute). Statistical significance was set at P < 0.05 a priori.

RESULTS

Beginning in 2000, the incidence of ATV injuries consistently increased over time and peaked in 2007 (54.1/100,000 people). Since 2007, the incidence of ATV injuries has consistently decreased (33.7/100,000 people in 2015). The frequency of ATV injuries differed significantly (P < 0.001) by age group, with children aged 14 to 17 years experiencing the highest incidence of ATV injury (2.8× national average). ATV injuries were also more common in males (2.7× national average; P < 0.001). The most common injuries were contusions and abrasions (25.3%), fractures (24.5%), and lacerations (11.4%). The decreased rate of ATV injury beginning in 2007 did not differ significantly (P = 0.81) from a comparative decrease in dirt bike-related injuries.

DISCUSSION

This study provides the most current data on ATV injuries presenting to EDs in the United States. The rate of ATV-related injuries has steadily decreased since 2007, which corresponds to the American Academy of Orthopaedic Surgeons public awareness campaign. However, the reasons for this decrease are likely multifactorial. Children aged 14 to 17 years are at high risk of ATV-related injuries, with orthopaedic injuries accounting for a notable proportion.

Helmets Matter: Kentucky All-Terrain Vehicle Crashes Seen at a Tennessee Trauma Center

All-terrain vehicle (ATV) safety laws, including helmet use, vary by state and are sporadically enforced. Kentucky state laws require safety helmets only for younger riders. We hypothesized that ATV riders injured in Kentucky and seen at a Tennessee trauma center would more likely be unhelmeted, have more severe head injuries, and have higher mortality rates than those injured in Virginia or Tennessee. A Trauma Registry review of 750 injured ATV riders from June 1, 2005, through June 1, 2015 examined state location of accident, helmet use, markers of injury severity, and outcomes. Multiple logistic regression analysis examined predictors of severe head injuries and death with P < 0.05 significant. Unhelmeted ATV rider status predicted more severe head injuries (relative risk 23.5, P < 0.001) and death (relative risk 4.6, P < 0.001). ATV riders injured in the state of Kentucky were twice as numerous. In addition, they were more likely than ATVriders injured in Tennessee or Virginia to be unhelmeted, to have severe head injuries, and to sustain fatal injuries (all P < 0.001). This single trauma center study lends support for maintaining and enforcing current universal helmet laws for ATVriders of all ages in states where they are in effect and highlights the need to upgrade helmet laws that apply only to some riders.

Age Legislation and Off-Road Vehicle Injuries in Children

BACKGROUND AND OBJECTIVES

In 2010, the Massachusetts Legislature passed a comprehensive law that restricted off-road vehicle (ORV) use by children <14 years old and regulated ORV use by children up to the age of 18 years. We aimed to examine the impact of the 2010 Massachusetts law on the rates of ORV-related injuries.

METHODS

A retrospective analysis was performed of Massachusetts emergency department (ED) and inpatient discharges between 2002 and 2013 as found in the Center for Health Information and Analysis database by using external causes of injury codes specific to ORV-related injuries. Yearly population-based rates were compared before and after the implementation of the law (2002-2010 vs 2011-2013) by using Poisson regression analysis and segmented regression.

RESULTS

There were 3638 ED discharges and 481 inpatient discharges for ORV-related injuries in children across the 12-year study period. After the implementation of the law, the rate of ED discharges declined by 33% in 0- to 9-year-olds, 50% in 10- to 13-year-olds, and 39% in 14 to 17-year-olds (P < .0001). There was no significant decline in ED discharges for 25- to 34-year-olds. Inpatient hospital discharges were also reduced by 41% in 0- to 17-year-olds after implementation (P < .001).

CONCLUSIONS

As compared with adults (ages 25-34 years), the population-based ORV-related injury rate of residents <18 years old significantly declined after the passage of legislation that imposed age restrictions and other safeguards for youth riders.

Using Geospatial Mapping to Determine the Impact of All-Terrain Vehicle Crashes on Both Rural and Urban Communities

INTRODUCTION

Deaths and injuries from all-terrain vehicle (ATV) crashes result in approximately 700 deaths each year and more than 100,000 emergency department (ED) visits. Common misconceptions about ATV crashes are a significant barrier to injury prevention efforts, as is the lack of key information about where and how crashes occur. The purpose of this study was to determine ATV crash patterns within a state, and to compare and contrast characteristics of these crashes as a function of crash-site rurality.

METHODS

We performed descriptive, comparative, and regression analyses using a statewide off-road vehicle crash and injury database (2002-2013). Comparisons were performed by rurality as defined using the Rural Urban Commuting Area (RUCA) coding system, and we used geographic information system (GIS) software to map crash patterns at the zip code and county levels.

RESULTS

ATV crashes occurred throughout the state; 46% occurred in urban and 54% in rural zip code areas. Comparisons of rider and crash characteristics by rurality showed similarities by sex, age, seating position, on vs. off the road, and crash mechanism. Conversely, helmet use was significantly lower among victims of isolated rural crashes as compared to other victims (p=0.004). Crashes in isolated rural and small rural areas accounted for only 39% of all crashes but resulted in 62% of fatalities. In both rural and urban areas, less than one-quarter of roadway injuries were traffic related. Relative crash rates varied by county, and unique patterns were observed for crashes involving youth and roadway riders. During the study period, 10% and 50% of all crashes occurred in 2% and 20% of the state's counties, respectively.

CONCLUSION

This study suggests that ATV crashes are a public health concern for both rural and urban communities. However, isolated rural ATV crash victims were less likely to be helmeted, and rural victims were over-represented among fatalities. Traffic was not the major factor in roadway crashes in either rural or urban areas. Unique crash patterns for different riding populations suggest that injury prevention experts and public policy makers should consider the potential impact of geographical location when developing injury prevention interventions.

Engaging Agribusinesses: Feasibility and Cost of an ATV Safety Poster Project

OBJECTIVES

All-terrain vehicle (ATV)-related deaths and injuries continue to be a significant problem. Influential change agents such as agribusinesses could be important partners for improving safety behaviors among rural ATV users. Our objective was to determine how effectively an injury prevention project could engage agribusinesses through the postal service and to assess their willingness to display a safety poster.

METHODS

One thousand two hundred forty-four agribusinesses received an ATV safety poster and a postcard survey by mail. A randomized sampling of these businesses was surveyed by telephone 4-7 weeks later. Telephone survey questions included whether they recalled receiving the poster, and if so, whether, where and how long the poster was displayed.

RESULTS

One hundred six postcards were returned. Of the 192 eligible business persons contacted by telephone, 89% agreed to participate. Approximately one-third of telephone survey participants recalled receiving the poster. Among these, 81% with walk-in customers posted it, and 74% still had it displayed 1 month later. Of participants who did not recall receiving the poster, 83% stated they would have displayed the poster. The cost of displaying each poster in a business was 16.6 cents/day during the first month. Final costs/day would be much less because of continued display.

CONCLUSION

A high percentage of agribusinesses displayed or would have displayed an ATV safety poster, and most displayed it beyond 1 month. Unfortunately, participant recruitment via postal delivery alone was challenging. Nevertheless, mass mailing of injury prevention materials to be displayed in the retail setting may be a low cost method for raising safety awareness.

All-terrain vehicle safety knowledge, riding behaviors and crash experience of Farm Progress Show attendees

INTRODUCTION

Although all-terrain vehicles (ATVs) are very popular in rural areas for both recreation and work purposes, the epidemiology of agricultural ATV use remains largely unknown.

METHODS

Farm Progress Show attendees in 2012 (Boone, Iowa) and 2013 (Decatur, Illinois) were surveyed about ATVs, including riding behaviors, crash history, and safety knowledge. Descriptive and comparative analyses were performed (N=635 surveys).

RESULTS

Over half of those surveyed lived on a farm and more than 90% had ridden on an ATV. Sixty-one percent rode at least once a week and 39% reported riding almost daily. Males and respondents who lived on farms were significantly more likely to be ATV riders. Regarding unsafe behaviors, >80% of ATV users had ridden with a passenger, 66% had ridden on a public road, and nearly one-half never or almost never wore a helmet. Nearly 40% reported having been in a crash. Multivariable logistic regression analysis of adult respondent's data showed males and younger adults were both more likely to report having crashed. In addition, those reporting riding on public roads (but not having ridden with passengers) were nearly five times more likely and respondents who reported both riding on public roads and having ridden with passengers were approximately eight times more likely to have been in a crash as compared to those not reporting these unsafe behaviors. Safety knowledge did not necessarily correspond with safer behaviors; 80% who knew there should be no passengers on an ATV still had ridden with extra riders.

CONCLUSION

ATV use is prevalent in rural populations and most riders report engaging in unsafe riding behaviors.

PRACTICAL APPLICATIONS

These findings may be used to inform ATV safety education and training programs targeted toward agricultural communities, with the goal of reducing occupational ATV-related deaths and injuries and their substantial economic costs.

Characteristics of Side-by-Side Vehicle Crashes and Related Injuries as Determined Using Newspaper Reports from Nine U.S. States

Side-by-side (SxS) vehicles have become increasingly popular, but there are few reports on injury epidemiology. Newspaper reports of SxS and all-terrain vehicle (ATV) crashes were analyzed for nine U.S. states from 2009 to 2011, including comparisons between the two vehicle types. Seventy-nine SxS crashes involving 104 injured victims were identified; three-fourths were males. There was a relatively high percentage of injured passengers (37%), and a higher proportion of female victims were passengers as compared to males (p = 0.015). Children <16 years of age were 44% of those injured and had the highest proportion of both passenger and operator victims as compared to other age groups. Over half of the crashes occurred on roadways; nearly two-fifths occurred at night. As compared to adults, a lower percentage of crashes involving youth were at night (p = 0.0037) but the percentages on roadways were similar. Only one in five roadway SxS crashes involved a collision with a motorized vehicle. Rollovers were the most common mechanism (50%). Two-thirds of victims were ejected, and one-half were struck or pinned by the vehicle. Twenty-eight deaths (27%) were reported. Although most current SxSs have roll bars, lack of safety belt use has likely reduced their benefit. Children should be prohibited from operating SxSs.
