What kind of test should I take at the police station—blood, breath or urine?

 

A: You probably will not be given a choice between three types of tests, but you may have to choose between two. The most accurate is the blood test and the least is urinalysis. This means that, if you are fairly certain you are below the legal limit, you should take the most accurate test to prove it. If, on the other hand, you believe it is likely that your blood alcohol is above the legal limit, the urinalysis test would be the most easily attacked in court.
