Quick Details

  • Place of Origin: Zhejiang, China (Mainland)
  • Brand Name: hankun

The Hankun 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. 

Hankun 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 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 (two or 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.
