An electronic sign which displays a message or speed when triggered by a vehicle

Vehicle activated signs (VAS)

Vehicle activated signs (VAS) are electric signs which display a message or speed when triggered by vehicles travelling at excessive speeds. The signs can display the speed limit or they can warn drivers of an approaching hazard. They are intended to supplement rather than replace the traditional signs and line and are aimed at addressing specific road safety problems.

A vehicle activated sign should be used strategically where they will have the maximum effect. To introduce them on a widespread basis as simply ‘another traffic sign’ would cause drivers to become used to them and their effect would diminish.

Indicative costs
