Tunnel aheadThis was the right answer
A tunnel can present a number of dangers to large vehicles. Look out for height or width limits and always be aware of your vehicle's size. Reduce speed and turn on your headlights before entering the tunnel. Remove sunglasses if you're wearing them, and remember, your eyes may take a little time to adjust to the sudden darkness.
