I can't answer for South Carolina or Georgia, but you do not need a permit to carry in the car as long as the gun is in a zippered case or snapped holster inside a closed compartment. You do need a permit to carry concealed and it is a felony to do so without a permit. Open carry just passed, but you still need a valid concealed carry permit to carry openly. I am not sure if the law has been implemented yet so I would not carry openly. Under the old law (possibly present law), open carry was considered a misdemeanor. Good luck and I hope everything is okay with your emergency trip.
