I am not a resident from Atlanta, but a former Los Angeles, California area resident with HOV lanes on the freeways. Motorhomes were allowed on HOV lanes because they did not have a speed limit restirction like large trucks and any type of trailers. Trucks and all trailers, in Calif, have a speed restriction of 55. All other were restricted to 65, including HOV lanes. So, since HOV lanes were restircted at 65, then trailers and large trucks were not allowed to use them. I would imagine its the same in Atlanta. To avoid a ticket from your local cops, I would call them to make sure. Good luck.
