DUI / Drunk Driving Checkpoints May Not Be Effective

According to the American Beverage Institute, DUI / Drunk Driving checkpoints are costly and ineffective.

Citing California statistics, in 2008, out of 1,000,000 motorists stopped at DUI checkpoints, only one-third of one percent were charged with DUI / Drunk Driving.

On the other hand, publicizing the locations of DUI / Drunk Driving checkpoints may have a deterrent effect on drinking drivers who are aware of the checkpoints and their locations. I wonder if a study will be done that measures the amount of time each motorist is stopped and use those results in the analysis of whether or not to conduct checkpoints.
