You can avoid mishaps like this so easily! Include a measuring tape in your Emergency Kit along with the spare wheel, fuses, lamp bulbs, foot-pump, tire levers, ring spanners, welding equipment, hoist, band-aid, vaseline, red triangle, bull horn, spare engine, tow-truck, thermos, sandwiches, tire chains, sleeping-bag, compass, ear defenders and so on which the thoughtful driver knows are indispensable for getting him out of tight corners. Tight corners are the bane of any motorist's life.
All this guy needed to do was measure the bridge before he tried to drive across it. But at least he had the foresight to bring some stripey tape and a policeman with him. Could have been nasty.
