The first if they may try and take away your drivers license. Depending on your age and criminal history, that can range anywhere from 60 days to 2 years. Also if you fail or refuse to take a breath test or blood test they can use it against you as a sign of intoxication in trial. However on the flip side you can also take it as a sign of sobriety (like you know better than to take the test.) And then the last if you refuse to take a breath or blood test the officers can apply for a warrant to try and take your blood.
