Parental perceptions of teen driving: Restrictions, worry and influence

Association of age and severe injury in young motorcycle riders: A cross-sectional study from Karachi, Pakistan

INTRODUCTION

The burden imposed by motorcyclist deaths and injuries is high in low- and middle-income countries. Many injured motorcycle riders in these settings are underage. The aim of this study was to assess the association between age and severe injury in young motorcycle riders.

METHODS

We analysed road traffic injury surveillance data from the emergency rooms of five hospitals in Karachi from 2007 to 2015. We used logistic regression to assess the association of motorcycle riders' age, categorised as underage (13-17 years), early licensing age (18-19 years) and late licensing age (20-24 years), with severe injury, defined as an Injury Severity Score (ISS) ≥ 16.

RESULTS

The study sample included 45,366 motorcycle riders. There were 10115 (22.3%) motorcycle riders aged 13-17 years, 9899 (21.8%) aged 18-19 years and 25352 (55.9%) aged 20-24 years. Almost all were male (99%). Being aged 13-17 years (adjusted odds ratio 1.25; 95% CI 1.11, 1.42) and 18-19 years (adjusted odds ratio 1.26; 95% CI 1.10, 1.43) were associated with higher odds of severe injury compared with being aged 20-24 years.

CONCLUSION

Motorcycle riders who presented to the hospital with injuries after road traffic crashes and were aged 13-17 years and 18-19 years had significantly higher odds of severe injury than those aged 20-24 years.

Graduated driver licensing (GDL) in the United States in 2016: A literature review and commentary

This is the sixth in a series of reviews of research on graduated driver licensing (GDL) published in the Journal of Safety Research, the present review covering the period mid-2012 through 2016. In the two decades since GDL programs began to be introduced on a widespread basis in the United States, a vast amount of research has been published. The current review discusses recent research and the present state of knowledge on the following topics: characteristics of the novice driver population; effects of GDL on crashes for ages 16-19; the learner and intermediate periods; night and passenger restrictions; cellphone laws; GDL for older novices; enforcement of GDL rules; and programs attempting to influence GDL compliance and safe driving practices in general. GDL stands out as a successful policy for reducing teen driver crashes and is worth building on to extend its benefits. Strengthening existing GDL programs has the most potential for producing further crash reductions.
