Radar-Speed Trailer - WSDT-S


The Wanco Radar-Speed Trailer is among today’s most advanced speed-display systems. With changeable speed limit indication and radar-triggered speed display, the Radar-Speed Trailer instructs motorists to slow down by flashing their excessive speed.

Commonly deployed in school zones, construction areas, neighborhoods and high-accident areas, numerous options provide a strong measure of traffic calming unmatched by other roadway signs. Additionally, the trailer’s see-through design makes for safer operation in dangerous high-risk areas, and its solar-powered battery charging system allows longer run times.
