Are random breath tests for drivers a good idea?   stance: great idea:
How are you going to enforce it? Stop people in the middle of the road, ask their license and registration, and conduct a breath test? "Sir, you have been randomly selected for breath test, please step outside of the car".
Will certainty give counties jobs for police officers, at the expense of tax payers.
Cops already doing tests if they suspect you were drinking -- it's not random but probable cause.
Guess what. if you were drinking and cops do not suspect your drinking habits, it is because your Alcoholic content is below DUI. Some cops don't like the extra effort, and paperwork stopping people for DUI. Do you think random testing will solve this problem?
