Evaluation of the California Drunk Driving Countermeasure System. Volume 4. An Evaluation of the Process Efficiency and Traffic Safety Impact of the California Implied Consent Program

摘要

The present study describes the California IC system and answers a number of questions related to the program's operational efficiency and effectiveness, the characteristics of its target population, and its impact on traffic safety. The results from the analysis of the traffic safety impact of the IC suspension demonstrated that suspending refusers is an effective countermeasure for the subgroup of the DUI population.
