I was actually including breathalyzer as a roadside test. I don’t think I’ve ever heard of anyone refusing to do the physical tests, although I suppose some have. Sorry for the confusion. Refusal to take either a breath or blood test will get a six-month suspension.
In GA there is a simple court filing within the first.... 2 days or something - it’s pretty quick - and you get your license back. If you wait after that then you aren’t going to get it back until after the trial (if you’re acquitted).
At least on the first DUI. Dunno about after that.
