The speed limit within city limits of Atlanta is 55 mph. The speed that traffic moves (excluding rush hour) ranges from 70 to 80 mph. At one time, the average traffic flow was close to 90 mph, but it has come down a little since then. If you are going 65, you are a severe traffic hazard. Don't even think about driving the speed limit! People who are not used to 8 extremely narrow lanes of heavy traffic going 70-80 mph can become extremely agitated. I don't drive in Atlanta unless I have to.
