Cobb County Government

Can stop signs be placed on streets to slow down speeding drivers?

The County offers two solutions: speed limit enforcement and traffic calming programs.

To request speed limit enforcement please contact the Cobb County Police Department by submitting a traffic complaint.

To request a traffic study for one of our traffic calming programs, please contact Traffic Operations by submitting a Work Request, or email us at, or call us at 770-528-1600.

Our traffic calming programs include installation of speed humps, on local roads with a speed limit of 25 mph, and deployment of speed trailers which display a driver’s speed adjacent to the posted speed limit for instant comparison.
