Life is so hard! I've been shamed into it and had to come in from the pool.

This study is a comprehensive review (reviews the results of many prior studies):

Elder, R. W., Shults, R. A., Sleet, D. A., Nichols, J. L., Zaza, S., & Thompson, R. S. (2002).
Effectiveness of sobriety checkpoints for reducing alcohol-involved crashes. Traffic Injury
Prevention, 3(4), 266-274.



The goal of sobriety checkpoints is to deter drinking and driving by systematically stopping
drivers for assessment of alcohol impairment, thus increasing the perceived risk of arrest
for alcohol-impaired driving. This review examines the effectiveness of random breath
testing (RBT) checkpoints, at which all drivers stopped are given breath tests for blood
alcohol levels, and selective breath testing (SBT) checkpoints, at which police must have
reason to suspect the driver has been drinking before demanding a breath test. A systematic
review of the effectiveness of sobriety checkpoints in reducing alcohol-involved crashes
and associated injuries and fatalities was conducted using the methodology developed for
the Guide to Community Preventive Services (Community Guide) . Substantial reductions in
crashes were observed for both checkpoint types across various outcome measures and time
periods. Results suggest that both RBT and SBT checkpoints can play an important role
in preventing alcohol-related crashes and associated injuries.
