Interstate weight limits
Federal law sets the Interstate limits at 20,000 lb on a single axle, 34,000 lb on a tandem, and 80,000 lb gross, with the bridge formula on every axle group (23 CFR 658.17). States may keep higher limits they had before the federal limits took effect ("grandfather rights").
Georgia's single-axle limit is 20,340 lb (18,000 lb + 13 percent, low-pressure tires), listed by FHWA as a grandfathered right.

FHWA's summary of Georgia law for trucks in regular operation (no permit), including non-Interstate highways. It reflects state law as of October 1, 2012; check the state for later changes.
- Single axle
- 20,340 lbs. (18,000 lbs. + 13 percent) with low pressure tires / 18,080 lbs. (16,000 lbs. + 13 percent) with high pressure, solid rubber, or cushion tires
- Tandem axle
- 34,000 lbs. / 40,680 on non-Interstate highways (if vehicle is less than 55 feet long and GVW is less than 73,280)
- Tridem axle
- Per FBF
- Gross weight
- 80,000 lbs.; subject to FBF if gross weight of vehicle is between 73,280 lbs. and 80,000 lbs.
- Other
- 1,000 lbs. tolerance on axle loads
Where Georgia allows more than federal limits
- Allows 20,340 lbs. on a single axle;
- Allows 40,680 lbs. on a tandem axle on non-Interstate highways;
- Allows 61,020 lbs. for a tridem axle on non-Interstate highways;
- Allows vehicles carrying several commodity types to exceed State weight limits on non-Interstate highways up to 23,000 lbs. on any single axle and 46,000 lbs. on any tandem axle; and
- Allows an additional 5 percent variance for transportation of specified commodities within a 100-mile radius of the point of origin; poultry waste is allowed the 5 percent variance within a 250-mile radius. Many of these exemptions are limited to transportation from a farm or other point of origin to a processing facility.
Height, width, and length
- Width: 102 inches. States may not set a width limit of more or less than 102 inches on the National Network (23 CFR 658.15(a)). Permits can allow wider loads.
- Height: 13 ft 6 in (truck and load). There is no federal height limit; each state sets its own.
- Semitrailer length: 53 ft ("the standard trailer unit in Georgia is 53 feet")
- Grandfathered semitrailer length: 48 ft. The minimum semitrailer length the state must allow in a tractor-semitrailer combination on the National Network, based on lengths legal in the state on December 1, 1982. Federal law also requires at least 48 ft (23 CFR 658.13(b)(1)).
Over these limits you need a permit. Georgia oversize/overweight permits (844-837-5500).
