Problem is in some states just declining means they take away your license (I think this is for breathalyzer/blood only, not “walk a straight line.”) So the gamble is “do I take the test and hopefully pass, or do I refuse the test and get screwed anyway?”
Of course if you take the test and fail, not only do they take away your license, they make you go to six months of classes to school you on how bad drinking is, which you have to complete to get your license back. This seems to guarantee a certain number of drivers will take their chances with the test.
