Dang. Gene pool and chlorine and all that stuff. As the holder of a CDL, I know I'm responsible to make sure I know the dimensions of the vehicle I'm driving. I also think that it's an advantage to be able to read and recognize numbers in order to drive. Just sayin'.
LoL considering how many rental trucks there were how much you wanna bet some of 'em were the same guy going "Son of a B!TCH! I did it AGAIN!" I loved the people who just kept going like, "well, maybe nobody'll notice" ... kind of like when you stumble on a crack while walking down the sidewalk.
We used to have a railroad overpass where I was born and raised and I don't know how many semi's and straight trucks got caught by it, but there were plenty of them. They finally lowered the roadbed to provide additional clearance just a few years before the railroad abandoned the line and they finally took the overpass out too.
