Effectiveness of Maryland's DUI roadblock & sobriety checkpoint plan disputed

In a letter to the editor published in Southern Maryland Online, a representative from the American Beverage Institute cites studies that show that roving patrols are far more effective in arresting drunk drivers than organized, visible roadblocks.

It is a reasonable assumption that roadblocks are not a particularly effective use of the limited enforcement resources of the police department. Big, showy roadblocks may make people believe that they are helping reduce drunk driving more than standard, quality police work, and now the evidence supports that belief.

It is always helpful when individuals and groups come together to honestly and objectively assess the best ways to prevent drunk driving. Too often, the neo-prohibitionist groups like MADD are the only voice in the discussion.
By the way, the American Beverage Institute is an industry group that represents bars and restaurants that serve alcohol, and is an important voice in fighting drunk drivers at the source.
