What the evidence says
The intervention focuses on sobriety checkpoints aimed at reducing alcohol-related injuries and crashes by stopping drivers to assess their level of alcohol impairment. Evidence indicates that these checkpoints effectively reduce alcohol-related incidents by increasing the perceived risk of arrest among drivers. The overall impact suggests an average of 14 fewer crashes prevented for every 100 crashes due to the implementation of checkpoints.
How it works
Checkpoints increase the perceived risk of arrest for drink-driving, thereby deterring potential offenders. Media campaigns accompanying the checkpoints help enhance public awareness and encourage compliance with drinking laws.
Implementation
Effective implementation requires securing adequate staff and resources, particularly during high-risk times such as weekends. High visibility and public awareness campaigns significantly enhance the effectiveness of such checkpoints.
