Reminds me of the time I was driving a dump truck approaching an underpass. There was a slow hydraulic leak that if one wasn’t watching would slowly raise the dump. About 100 feet and four or five seconds before I went under it I glanced in my side mirror and saw the raised dump. All stop! :)
Back in March, this truck's raised dumper hit a pedestrian bridge over I-90 in Cleveland. The bridge had to be torn down. The truck didn't do too well, either.
