DUI Georgia, car parked when arrested

Is there anyway to beat a dui charge if you weren't caught driving???: My boyfriend was driving home after drinking and he caught a flat tire, ran up on a curb and grazed a light pole. He got out to change his tire and after about 20 min, while he was on th side of the road, a police officer drove up. He called me to come pick him up. When I got there the officer was parked behind him while he attempted to change his tire. After a while another police officer pulled up, noticed the damage on the car, noticed he was drunk and proceeded to arrest him for dui. He blew on the sid eof the road but the test didn't register so they tested him again at the police station. He blew a 158. We live in Georgia and this will be his 2nd dui (his last one was two years ago). My question is, are there any avenues we should explore as far as beating his charges since he was no caught driving or even in his car? The car was not even on, nor were the keys in the ignition. We have researched and we discovered that in Georgia for a second dui conviction in 5 yrs there is a mandatory "hard" suspension of license for 12 months. Which means no permit to drive to work. Is there any way to bypass this penalty? He works 45 minutes away from his home and if he can't get to work, then he can't make money, and he can't pay fines. Someone, please help. We are so lost. Thanks!!!
