The worst one I saw was driving to work one day on I30 near Dallas. A large box truck had been converted to a car hauler. 4 small cars on a good day. This day they decided to put 2 cars on the bottom and a Ford Expedition and a pickup on top. The expedition was on top in front. Apparently no one had checked the height. I got there just after they had tried to go under one of the lower overpasses in the area. It was still 16 feet/4.8M plus. There were pieces of the Ford Expedition all over the freeway for a 100 yards/meters. The biggest piece was the rear end. At 75mph/120kph and the slicing action of the I beam, there wasn't much left that was recognizable. The pickup had been flipped off the back and was still hanging by the rear chains.
The driver looked sick. There may have been a good reason, some cases these clearence incedents are not covered by insurance.

About 1987 driving on the east side of Rowlett TX, going south on Dalrock road. A big road for the town then. A Saturday about 6:30 am. A garbage truck was headed north, speeding and the front dump lift was not locked down. Garbage truck hit a bump in the intersection and the front lift arms jumped up about 5 feet/1.5M. The arms caught a power line crossing the road and were pulled all the way up. The truck wasn't even slowed as it caught the line and busted 2 telephone polls from either side of the street. When the poles busted, the tension dropped, the arms went down and the power line slid over the top of the truck and was dropped in the street. They were dropped about 20 feed in front of me with no time to stop. I ran over the live power line, but avoided the poles.
The garbage truck kept right on going without slowing down. It is not something the driver could ignore, the noise of the arms banging up and down could have deafened the driver. When I called 911 they were a little dumbfounded, but got on it right away. I identitified the garbage collection company also. I didn't see garbage trucks speeding through town after that. The bill from the power company was probably enough incdentive for the garbage collection agency to better train the drivers to follow speed limits and lock down the hydraulics.
The poles were replaced and the road opened in about 4 hours. The lines were a couple of feet/600mm higher this time.
