Multi-component community interventions against alcohol-impaired driving

Evidence Rating  
Scientifically Supported
Evidence rating: Scientifically Supported

Strategies with this rating are most likely to make a difference. These strategies have been tested in many robust studies with consistently positive results.

Health Factors  

Multi-component interventions with community mobilization focused on alcohol-impaired driving can include many components, such as: sobriety checkpoints, training in responsible beverage service, education and awareness-raising efforts, and limiting access to alcohol1.

Expected Beneficial Outcomes (Rated)

  • Reduced alcohol-related crashes

  • Reduced fatal and non-fatal injuries

Evidence of Effectiveness

There is strong evidence that multi-component interventions with community mobilization reduce alcohol-related crashes1. Such interventions have been shown to reduce fatal crashes, nighttime injury crashes, and crashes among drivers aged 16-20 in a number of communities1. Multi-component interventions may also lead to cost savings resulting from the reduction in injuries, fatalities and property damage from alcohol-related crashes2.

Impact on Disparities

No impact on disparities likely

Implementation Examples

The Community Trials Intervention to Reduce High-Risk Drinking is an example of a multi-component intervention3.
