Alcohol involvement and other risky driver behaviors: effects on crash initiation and crash severity.

Conclusions: Risky driving behaviors, including alcohol involvement, increased the risk of a crash. Crash severity tended to increase with any risky behavior and to increase further with multiple risky behaviors. Other risky behaviors were associated with both alcohol involvement and crashes. Therefore, if effects from those other risky behaviors were not accommodated for, those effects would confound apparent associations between alcohol involvement and crashes. Therefore, this study's use of multivariate models that accommodated for effects from those other behaviors provided a truer picture of alcohol's association with crashes than simpler models would have.
