Commonly deployed in school zones, neighborhoods and high-accident areas, numerous options provide a strong measure of traffic calming unmatched by other roadway signs. The Wanco radar-speed trailer features a changeable speed limit sign above an electronic display.

Wanco engineers designed the new full-matrix display to be the largest, most visible display on the market. The compact, portable trailer is suitable for use in neighborhoods as well as major roads with heavy traffic.

When a motorist exceeds the speed limit, the display flashes the vehicle’s speed. For excessive speed, a selectable overspeed message flashes “slow down” or a frowning face or other symbol, together with optional flashers that attract attention.

Factory-configured units show motorists’ speed in mph (one or two digits) or km/h (up to three digits — see international model). The display’s LEDs have visors and shades that produce superior angularity and visibility.

A regulatory sign above the display features changeable speed-limit numbers for easy setup in any speed zone.

The trailer’s see-through design puts pedestrians in view, improving their safety—particularly in dangerous, high-risk areas. The solar powered battery-charging system provides longer run times.
