Red Light and Speed cameras are used in various municipalities throughout Tennessee. These municipalities include Memphis, Knoxville, Chattanooga, Germantown, Clarksville, Murfreesboro, Hixson, Red Bank, Morristown, Johnson City, Kingsport, and others.
There are also cameras mounted on traffic signals that are used as part of the signal control. These compare sequential images of the intersection approach to determine if there is a vehicle (car, truck, motorcycle, bicycle, etc) waiting and will trigger the sequence. These devices CAN NOT issue tickets and should not be mapped.
There are traditional traffic monitoring cameras covering most of the major highways in the state. These send live video to TDOT & local media and serve ONLY as a traffic monitoring system and should not be mapped.
