The second had a metal plate and was easier to read. It also was the same procedure so not hard to know what to do. I pressed the button. There are flashing red lights, an audible alarm and then a red and white gate lowers across the road, like at a level crossing. A driver approached, went well beyond the stop line and the barrier landed on his car. I stopped the barrier and pressed the close button so it reversed it’s procedure and raised the barrier and he drove across, then stopped and his passenger got off to check for damage. Luckily it was unscathed. I’m not sure what part of stop line, flashing lights and sirens, that driver failed to notice, but slightly worrying that he’s still driving. We completed the bridge opening and closing without incident.
