I got one recently myself... refused to blow. Turns out that is an "automatic admission of guilt" or something. I'm probably going to lose my license for a year, $800-1500 fine, 0-2 days in jail, and possibly a 3-session Drug & Alcohol Class.
I'm normally not one to drink and drive. I'd done a *bunch* of tequila shots like a dumbass and I'm a big guy so it hadnt hit me when I started driving. I had to drive about 3 miles and thought I'd be cool to go there, handle my shit and come back, then not drive the rest of the night. However, it hit me as I was driving thru residential hoods. Ended up going down a 2 lane one-way into oncoming traffic and swerving off the road to avoid hitting people and went up over a curb & grass so fast I cracked a rim (tire did not pop tho) and the car landed in a parking lot. I stumbled out and was like blanking out as I was talking to these people. One guy says "that security guy is calling the cops". Cops get there in like 2 minutes b/c its downtown and I get busted. I'm sure I talked to the cops but cant remember saying anything to them but "I'm cooool. I'm coooooool" (like Wil Ferrell in "Old School" when he gets shot with the tranq dart).
