Variable Speed Limit Sign

Displaying clear speed limits near school zones is crucial to ensure the safety of schoolchildren while maintaining smooth traffic flow. Orange Traffic therefore designed a variable speed limit sign equipped with dual yellow flashing lights specifically for use in school zones.


Orange Traffic’s variable speed limit sign can display two speeds, i.e., 30 and 50 km/h in urban areas or 50 and 70 km/h in rural areas. High-quality LEDs display the numbers, which are easy to read from a distance of 200 metres and fully invisible when they are not lit.

This sign comes with Orange Traffic’s SPC-22 programmable GPS clock and can be programmed years in advance with schedules that include statutory holidays, weekends, weekdays, vacations and other dates (perpetual calendar).

Furthermore, Orange Traffic can equip this sign with solar panels for autonomous operation as well as with a WiFi transmitter-receiver enabling remote configuration (optional).
