That is why I run a Garmin RV760, it will let know where the low overpass are. It warmed me of a railroad overpass down at Beaver Lake Arkansas that would of required me to back up about mile on heavy travel road and turn around in a very narrow private driveway. It is worth every penny I paid for it and even has free upgrades for life.
Well....except that it's database only knows what has been pointed out before - the clearance posted is usually the least. My Dezl 760 tried to reroute me hundreds of miles away and then back to 101 in California. And it is almost impossible, sometimes, to find why it decides to take the long way. Not until I was a couple of miles away did it start to scream at me about low overhead ahead. No possible way to turn around on that highway! Several RV's coming at me in the other lane, so with white knuckles, I forged ahead. Came to a tunnel, clearly posted as 11'6" (I'm 12'), but the opening was arched, so by being close to the yellow line, I cleared by several feet. Maybe if I had been as far over on the shoulder as possible, I might have touched.
Not saying to ignore it, as it sort of did it's job - but we would have missed a lot of spectacular scenery if we trusted it without knowing why it was telling us not to go!
