There is a school zone 2 blocks up Clairmont Avenue from Commerce Drive and police wait at a cross street to get anyone going over 25 miles per hour. It’s pretty obvious when you’re coming from Commerce Drive, but when you’re coming towards Commerce Drive from North Decatur Road, there is a flashing school sign, then nothing for several blocks to tell you that you are still in the school zone. But five blocks later the police will still stop you for it being a school zone and if you are going 10 miles per hour over, the fine is over $300.
