Drugs and Alcohol: Their Relative Crash Risk

Drugs and alcohol: their relative crash risk.

OBJECTIVE The purpose of this study was to determine (a) whether among sober (blood alcohol concentration [BAC] = .00%) drivers, being drug positive increases the drivers' risk of being killed in a fatal crash; (b) whether among drinking (BAC > .00%) drivers, being drug positive increases the drivers' risk of being killed in a fatal crash; and (c) whether alcohol and other drugs interact in inc...

Research Note: Drug and Alcohol Crash Risk

Background and Introduction While the extent of use of alcohol by drivers and the risks posed by alcohol use have been well known for many decades, relatively little has been known about the use of other drugs by drivers and the associated risks. However, drug-impaired driving has recently become an issue of increasing public and governmental concern in the United States and in many other count...

Crash Risk of Alcohol Impaired Driving

In order to determine the relative crash risk of drivers at various blood alcohol concentration (BAC) levels a case-control study was conducted in Long Beach, CA and Fort Lauderdale, FL. Data was collected on 4,919 drivers involved in 2,871 crashes of all severities. In addition, two drivers at the same location, day of week and time of day were sampled a week after a crash, which produced 10,0...

Young Drivers and Their Passengers Crash Risk and Group Processes

Studies have shown that the effect of passengers on accident propensity among young drivers is ambiguous—in some cases positive and some negative. In Sweden, various kinds of information are compiled in registers, including a national accident database and exposure data collected in a national investigation of the driving habits of license holders. Access to such data offers a good opportunity ...
