Sobriety checkpoints or roadblocks have been implemented in several jurisdictions to increase both the number of drunk drivers apprehended and the public’s perception of the risk of apprehension. The present study was conducted to obtain additional information on the effectiveness of such checkpoints as implemented in a medium sized urban community. A time series design consisting of 126 weeks of data was utilized to measure the impact of sobriety checkpoints on the number of alcohol related crashes.
