Low-Manpower Checkpoints: Can They Provide Effective DUI Enforcement in

Objective: When well publicized, sobriety checkpoints can be a highly effective means to reduce alcohol-impaired driving and its associated crashes. One reason checkpoints are underutilized is that police departments commonly believe a large number of officers are required, placing checkpoints beyond the resources of small police agencies. Studies have shown that checkpoints can be conducted successfully and safely with as few as three to five officers. The objective of the present study was to evaluate the impact of conducting small-scale checkpoints in rural communities on impaired driving and perception of enforcement. Methods: Law enforcement agencies in two rural counties in West Virginia agreed to conduct weekly checkpoints in their communities for one year. These counties were paired with two non-adjacent counties that did not undertake additional checkpoints. The impact of checkpoint operations was evaluated by conducting public awareness surveys at driver licensing offices as well as roadside surveys (including blood alcohol concentration (BAC) measurements) of weekend nighttime drivers in experimental and comparison counties before program initiation and one year later. Results: The percentage of nighttime drinking drivers in the experimental counties was lowe
