**In Georgia the rural interstates are posted at the maximum speed limit of 70 mph (113 km/h). Sections of Interstates passing through a municipality or metropolitan area with a population over fifty thousand are posted as high as 70 mph (113 km/h), such as I-95 through Brunswick and I-85 in Gwinnett County. Most urban interstates, however, still remain at or below 65 mph (105 km/h). I-285 in the Atlanta area is posted at 65 mph (105 km/h) – with variable speed limits on the north portion.**

I-95 and I-16 through suburban Savannah – the 65 mph (105 km/h) limit on I-95 is only for a 1 1/2 mile section in the vicinity of the I-16 interchange, I-16 from the interchange with I-75 in central Macon eastbound past Exit 2 is at 65 mph (105 km/h), and I-185 in Columbus remain at 65 mph (105 km/h), while the Downtown Connector and portions of I-20 in Atlanta are posted as low as 55 mph (89 km/h). Most non-interstate freeways such as GA-400 and the Athens perimeter highway, are posted at 55 to 65 mph (89 to 105 km/h).

Four-lane arterials and expressways can be posted as high as 65 mph (105 km/h). However, Dillon’s Rule enables counties outside municipalities to keep four-lane GRIP corridors at 55 mph (89 km/h). However, in recent years, US 1 between Augusta and Wrens raised the speed limit to 65 mph (105 km/h). Other rural four-lane highways with a 65 mph (105 km/h) include portions of US 441 near Irwinton, US 25 between Augusta and Statesboro, State Route 88 between Sandersville and Wrens, State Route 16 between Griffin and I-75, much of US 341 between Brunswick and I-75, and much of US 82 in South Georgia.

Two-lane state roads by default are posted at 55 mph (89 km/h). County maintained roads will rarely post any roadway above 50 mph (80 km/h) in middle & south Georgia, 45 mph (72 km/h) in north Georgia. Both in the Atlanta area, Ronald Reagan Parkway is posted at 50 mph (80 km/h) as a county maintained freeway and Sugarloaf Parkway is posted at 55 mph (89 km/h) along its new eastern freeway portion.

Inside the municipality, speed limits are generally posted at 35 mph (56 km/h) while it is 25–30 mph (40-48 km/h) in the downtown area.

All roadways maintained by the Georgia Department of Transportation that are subject to speed limit reductions are given advanced notice with signage that says “REDUCED SPEED AHEAD”. Furthermore, GDOT has a policy of doing 5 to 10 mph (8 to 16 km/h) increments but never higher than 10 mph (16 km/h).

Georgia is one of few states with anti-speed trap laws passed in the late 1990s. Speed violations less than 15 mph (24 km/h) over the speed limit will have no points assessed. Fines are not assessed for motorists going less than 10 mph (16 km/h) over the speed limit. In 2009, Georgia introduced the “Super Speeder” law, which adds an additional speeding fine of $200 for motorists convicted of traveling 75 mph (121 km/h) or more on a two lane or undivided road and 85 mph (137 km/h) or more on a divided highway.
