The City's most successful deterrent to speeding is the use of radar enforcement and the speed trailer. A speed trailer is a device used by the Police Department to supplement radar enforcement. The display board shows the posted speed limit and the speed of the vehicle approaching the trailer.
Drivers become aware of the speed they are traveling and many slow down.
The trailer can be used on most streets that are wide enough to park the trailer out of the way of traffic. It cannot be set up on streets where it will be even partially in the travel lane. Pavement undulations are only used after all other efforts have been exhausted. In addition, they can only be installed on streets that meet established engineering criteria. Many neighborhoods have homeowners associations or a neighborhood watch group.
