Manufacturer: Wanco®


The new Wanco radar-speed trailer with full-matrix display features the largest portable speed sign available today. Visible over a standard Jersey barrier traffic divider, the giant display shows motorists’ speed in 26-inch characters, warning motorists to slow down by flashing their excessive speed.


Commonly deployed in school zones, neighborhoods and high-accident areas, numerous options provide a strong measure of traffic calming unmatched by other roadway signs. Wanco engineers designed the new full-matrix radar-speed display to be the largest, most visible display on the market. The compact, portable trailer is intended for use in neighborhoods and alongside highways. 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 symbol, together with optional flashing red-and-blue “police” lights 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). A regulatory sign above the display features changeable speed-limit numbers for easy setup in any speed zone. The speed-limit sign and electronic display rotate to face traffic. The display’s LEDs have visors and shades that produce superior angularity and visibility. 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.
