background: motor vehicle traffic injuries are indeed one of the most important worldwide health problems. opioids can induce a depressant effect on the central nervous system which may increase the risk of traffic accidents. this cross-sectional case-control study was conducted in marvdasht, iran to investigate the presence of drugs in hospitalized non-fatally injured drivers of motor vehicles...

The proportion of motor vehicle crashes that involve a drowsy driver likely is greater than existing crash databases reflect, due to the possibility that some drivers whose pre-crash state of attention was unknown may have been drowsy. This study estimated the proportion of crashes that involved a drowsy driver in a representative sample of 47,597 crashes in the United States from 1999 through ...

OBJECTIVES Older drivers have become a larger part of the driving population and will continue to do so as the baby boomers reach retirement age. The purpose of this study was to identify the potential effects of this population increase on highway safety. METHODS Driver involvement rates for all police reported crashes were calculated per capita, per licensed driver, and per vehicle-mile of ...

CONTEXT Implementation of graduated driver licensing programs is associated with reductions in crash rates of young drivers, but graduated driver licensing programs vary in their components. The impact of programs with different components is unknown. OBJECTIVE The purpose of this work was to determine which graduated driver licensing programs are associated with the greatest reductions in fa...

Graduated driver licensing (GDL) programs are specialized licensing systems for beginner drivers adopted in all U.S. states, Australia, Canada, and New Zealand. GDL programs reduce novice drivers' exposure to high-risk driving situations while they gain driving experience. Several studies document the success of GDL programs overall in reducing young teen crash rates. However, little is known a...

Graduated driver licensing (GDL) laws now exist in all 50 states and the District of Columbia in the United States. These GDL systems are designed to reduce the exposure of young novice drivers to risky situations (such as late-night driving and driving with other teen passengers when alcohol is likely to be involved). Our aims were to determine if (a) GDL laws reduce fatal crash involvements o...

This work was performed to determine relations between car mass and driver injuries (serious or fatal) when cars of similar mass crash into each other head-on. This type of crash is examined because it is considered similar in some respects to a barrier crash. Data from the United States Fatal Accident Reporting System (FARS) are used to examine driver fatality likelihood as a function of car m...

Survey data on large trucks involved in fatal accidents and on the travel of large trucks provide estimates of fatal accident involvement rates by driver age. The analysis is focused on the implications of lowering the minimum age for drivers of commercial trucks operating interstate from 21 to 19 years. Fatal accident involvement rates for drivers of large trucks are found to increase with dec...
