The left lane is meant for passing only, and if you're caught riding in this lane with someone coming up faster behind you, you could get a ticket.
Driving in the left lane leads to traffic congestion and road rage therefore, Georgia passed the 'Slowpoke Law' in July 2014 to help with this problem.
The law states if you are driving in the left lane and cars are quickly coming up behind you, you must move over - even if you are going the speed limit.
If you are ticketed for impeding the flow of traffic you may receive a fine up to $1,000, 3 points on your license, and a substantial increase in your insurance premiums.
So whether you're on I-20, I-85, I-75, I-285, I-16, or I-95 the best thing to do, once you pass a car using the left lane is to get back over in the right-hand or middle lane.
