Speed-monitoring trailers—sign boards on trailers that display the speed of passing vehicles—are used by police departments and transportation agencies as educational tools that can enhance enforcement efforts directed at speed compliance. Speed radar trailers are best used in residential areas and may be used in conjunction with Neighborhood Speed Watch or other neighborhood safety education programs. Speed monitoring equipment may also be used in other types of areas where speeding is a problem, and/or where other roadway improvements have not been effective in keeping vehicle speeds at acceptable levels. Speed trailers help raise residents’ awareness of speed, but are not substitutes for permanent actions, such as traffic-calming treatments, to address neighborhood speeding issues.
Speed-monitoring trailers can be used at several locations and should have police monitoring and enforcement to maintain driver respect. Many cities will place speed trailers at the requests of residents.
