Here in Boston on Storrow Drive, they have overpasses that are REALLY low, just over 10 feet (perhaps 10,4”) and they have big metal hanging things that bash into your vehicle about 40 yards away, but...
People still find a way to get wedged under them. You would think one of the stoned college students would say “Dude! What was that noise?”
But, no.
We have some in Little Rock that are the same. One in particular on 9th Street is 10'6". One of my new drivers, in 2005, drove a 13'6" box truck under that overpass - never hit the brakes and made it all the way through. The top was peeled off like a sardine can. $46,000 in damage in under 5 seconds.
