Case Studies Suggest Practical Ways to Increase the Visibility of High-Visibility Enforcement Programs.

摘要

High-visibility enforcement (HVE) models are an effective strategy to reduce impaired driving. They work by increasing drivers perceived risk of being stopped and arrested by law enforcement if they choose to drive while impaired by alcohol or drugs. Two common enforcement strategies are sobriety checkpoints and saturation patrols. Checkpoints concentrate law enforcement officers at the roadside to identify impaired drivers who are passing through. Saturation patrols direct additional officers to patrol a limited area where impaired driving is prevalent. Both strategies use highly visible elements to ensure motorists see them. When publicity and communications combine with enforcement efforts, the result is a rise in awareness and the perception of an increased likelihood of detection of impaired driving among drivers.
