Ok, im 26 yrs old so i have learned this recently. In the state of Ga, if a driver refuses to take a breath-o-meter(lol) then they are taken to jail under a dui charge. and if i'm not mistaken then they do a blood test. if negative i guess there is no charge. I have been offended late at night being asked for a breatholozer, and the sad part is one night i called in a wreck that was a dui and it looked like the guy flipped, so i went back and waited for the 5.0. the cop kept me there for 2hrs b/c he stated he could not tell which one of us had been drinking, i got a little smart with him. my brother was locked up in a car i just bought b/c he thought it was stolen, you have every right to disagree if you are right. and the 5.0 has to have substantial evidence to think you are drinking, i have never been asked to blow, but i would be pissed if i had not been drinking, which i rarely do!!!!!!!!! that is a rant, some cops are good, some are bad, my grandfather was a athens pd back in the day!!!!
