I heard that as well. They only have 2 or 3. I don't know what the BAC legal limit is here. Normally the police would take you to a doctor and he would take a look at you to determine if you were legally intoxicated or not. Those of us..... I mean those people who can hold their alcohol and function ok will normally get a pass or a lesser charge.

Fortunately I have yet to see one. Could be the $20 model they are selling to consumers at Sam's Club. I'll venture to guess your get out of jail fee goes from $40-$50 up to $150 if you blow dirty.
