Low clearance overpasses can be a real concern for RVers as the video below illustrates. Despite the warning signs and flashing “Overheight” lights at this Durham, NC, 11-foot-8 clearance railroad trestle, the driver tows his fifth wheel under and cleanly scrapes the air conditioner off the roof. Not sure if he even knew what happened.
So many high-clearance vehicles crash into the trestle the railroad installed a steel crash beam in front of it. Believe it or not – they have already replaced the beam once!
RVers must know the height of their motorhomes and trailers and add an additional six inches for safety. RVers most always be aware of all overhead obstructions and when in doubt about height avoid going under them.

First thing to do is measure your camper height and write it down so you know what you need for clearance. Second purchase a Road Atlas for truckers and carry it in your drive vechile. They list overhead heights, speeds, legal lentgths, etc. When you’re off the main roads and in town, you personally must always be aware of low underpasses coming at you. Only you can prevent an accident!
