Abstract
This is the first report from a major study designed to identify ways to improve the efficiency and effectiveness of the DWI system for dealing with hard core drinking drivers. The present report underscores the need for system improvements by identifying key problems in the enforcement of DWI laws, and recommends practical solutions derived from prior research and validated by the experiences of several thousand front-line officers who participated in the project. Forthcoming reports will examine system improvements related to prosecution, sanctioning, and monitoring of hard core offenders. (Author/publisher)
