Early Evaluation of a Statewide Sobriety Checkpoint Program

In 1993, New Mexico launched a two year statewide sobriety checkpoint program intended to reduce the state's alcohol related fatal motor vehicle crashes (MVC). At initiation of the program in 1993, the rate was 57%; the goal is to reach 43% by 1996. By the end of 1994, it had dropped to 51.8%. During the past 18 months, 231,000 vehicles passed through 649 checkpoints. Program objectives consist of sending a strong public message that the consequences of driving while intoxicated are certain, severe and swift. Program evaluation includes a time-series analysis of statewide MVCs; a telephone survey regarding drinking and driving; and reports from the police department, who staff the sobriety checkpoints.
