Speed Limit Alert™ Display

The multi-featured Speed Limit Alert™ displays are a great solution for locations where the speed limit varies by time or traffic conditions and where compliance is critical.

The displays integrate speed-sensing radar and an LED display within the familiar, easily recognized format of a regular Federal Highway Administration (FHWA) R2-1 speed limit sign.

With one display, approaching drivers can clearly read the speed limit currently in effect, and are quickly warned to slow down if they are exceeding that limit.

Speed Limit Alert displays are ideal for high-risk pedestrian areas, such as school zones, parks and residential areas. Our customers also use them in work zones, hazard approaches, and where high-speed roadways lead into commercial or residential areas.

With ViolationAlert™, the display flashes the LED digits alerting drivers they are exceeding the posted speed limit. The faster the speed, the faster the Speed Limit Alert LED digits flash.

Add our SLOW DOWN message option when a stronger visual warning is needed. The display's SLOW DOWN message can be programmed to flash by itself, or to alternate flashing with the current posted speed limit.

Using our DeviceManager™, Speed Limit Alert displays can trigger external devices such as flashers and strobe lights, when drivers are exceeding the current limit.

SpeedCheck displays are programmed on location with our DisplayManager™ application via wireless Bluetooth connection, or, with our DisplayManager Central Office application, you can control them remotely from your desktop.
