The Drinking and Driving Component, one of five elements of the Community Trials Project, involved the implementation of a special drink driving countermeasure in the three experimental communities, one in Northern California, one in Southern California and another in South Carolina. This intensified enforcement of driving under the influence (DUI) was designed to deter potential drinking drivers by increasing their perception of the risk of being arrested leading to a reduction in the consumption of alcohol before driving. See component detailed description in Voas (1997, this issue). The evaluation found that media advocacy training and technical assistance resulted in increased DUI news coverage and that additional police officer hours for DUI enforcement, greater use of breathalyzer equipment, increased officer training and more checkpoints produced increased DUI enforcement. The combined effects of increased DUI news coverage and DUI enforcement yielded increased public perceived risk of arrest and subsequently less drinking and driving. Overall the evaluation found that alcohol-involved traffic crashes were reduced as a result of this component in the experimental communities as contrasted with the matched comparison communities.
