These guidelines and recommendations provide the best practices for radar speed sign installation to assure successful, accurate and effective traffic calming.
Do not install a solar powered radar speed sign under a tree. Summer leaves on the tree could impact solar recharging.
The radar speed sign should have at least 75 feet of straight road for on-coming traffic.
The radar speed sign should be installed no more than 5 feet from the road curb. At more than 6 feet from the road, the sign will take the eyes of the driver an unsafe distance from the roadway.
The sign direction should be perpendicular to the road with the radar pointing directly at the curb, not at the center of the road.- Prior to radar sign installation look for any obstructions (telephone poles, large tree limbs, other signage, etc.) that might interfere with proper operation of the sign.
- Installing the sign on the same side of the street as parallel parking of vehicles could affect the radar performance of the radar speed sign.
