Good news...........
If the driver is stopped in traffic, and shuts the car off, puts it in Park, and puts the keys in their lap, they should be in compliance with the law of our state.
Bad news...........
In the state of Georgia it is illegal to text and drive. If the cop sees you, he will even examine your "sent" messages to verify his observation.
All you northerners traveling south...........just a little heads up.
For the OP, sorry your overnight trip got messed up by construction.
One last thought..................I do not support texting and driving, but wanted to fill folks in on the circumstances in Georgia.
