§ 40-8-76.1. Use of safety belts in passenger vehicles

(a) As used in this Code section, the term "passenger vehicle" means every motor vehicle designed to carry ten passengers or less and used for the transportation of persons but shall not mean pickup trucks, motorcycles, motor driven cycles, or vehicles equipped for off-road use, provided that the term "passenger vehicle" includes any sport utility vehicle and also includes pickup trucks for any occupant who is under 18 years of age.

(b) Each occupant of the front seat of a passenger vehicle shall, while such passenger vehicle is being operated on a public road, street, or highway of this state, be restrained by a seat safety belt approved under Federal Motor Vehicle Safety Standard 208.
Don't think you have to wear them if you're over 18, and if it was made before something like 1965 its not required to have them installed.
