I don't practice in GA. It may be. A cop can certainly look up your license off the copy. But I'd research the particular law regarding driving w/o license in GA before doing it.

GA law requires you to have your license on your person when you drive. It carries a fine of $20 or so. The only concern I would have with you keeping a copy of it in your car for those times when you forget your wallet is identity theft. Don't make a copy of it; better to remember NOT to leave your wallet at home. As long as you remember your DOB and name, an officer can look it up.
