Overtake Warning Light / Traffic safety

Overtake Warning Light
Overtake Warning Light

The Overtake Warning Is designed to increase the safety of people walking in front of buses when another car want to overtake the bus.This is why many accidents happen because the traffic following the bus cannot see the walker. This new product, which is installed in the bus, projects light to the outside, with a STOP sign in red that says SLOW DOWN in letters, to halt any traffic coming up behind the bus, so that they can safely walk over.
