That's... I don't know where you got that from... Probation doesn't take blood samples. You pee in a cup. Trust me. I got 4 months left... And refusing a breathalyzer is so that you avoid blowing way to high on a DUI charge. If your twice the limit there's a stiffer penalty. By not blowing, you lose your license for a year automatically, at least in the state of Florida, but you can avoid fucking yourself by not submitting to a breathalyzer.
