RADAR TRAILER

A radar trailer is a device that measures each approaching vehicle’s speed and displays it next to the legal speed limit in clear view of the driver. They can be easily placed on a street for a limited amount of time then relocated to another street, allowing a single device to be effective in many locations.

Advantages

• Portable
• Does not physically slow emergency vehicles or buses
• Quick implementation

Disadvantages

• Effectiveness may be temporary
• Drivers may divert to alternate streets due to uncertainty of devices implications
• Subject to vandalism
