Overheight Warning sign

LED Overheight Triangle Warning Sign

Costly bridge strike costs could be avoided with overheight detection signage

Overheight detection systems are a highly accurate solution capable of detecting vehicles using break beam or bi-directional technology.

Should the detectors be triggered, an alert is sent to the Central Management System (CMS) so the user is aware there has been an over height vehicle approaching a bridge and the warning sign is illuminated.



Multi-stage dimming to ensure the best performance


Product Options

Break beam or bi-directional technology
Multiple sensing device options available including Photoelectric Gates, above-ground detection (Flir and AGD Cameras) or inground detection (loops or studs)
FLIR camera or radar to register the direction of traffic

This vehicle activated LED highway overheight warning sign is manufactured from 3mm aluminium and coloured black with powder coating. The sign has ULTRA Bright LED amber corner flashers and a display text of “OVERHEIGHT VEHICLE DIVERT” with an arrow. The text is to be displayed in capital letters, all in white LED’s.

In order to operate the sign, a remote overheight vehicle detector is installed at a designated point on the the approach of the low bridge. Once an overhight vehicle is detected as approaching the sign the system transmits a signal to the sign, which then activates the display for a pre-determined length of time.

Multiple sensing device options including Doppler Radar, IR gates, FLIR or a combination.

The sensors involved within the overheight detection technology can be set at a height to suit the application required. These applications can include bridge decks, car park height warnings, overhead power lines and overhead infrastructure which needs protecting and could be susceptible to collisions.
