Stuck Semi:
Don was driving his semi under an overpass when suddenly he came to a screeching halt. Don wasn’t paying enough attention and inadvertently drove under the overpass that was just barely as high as his truck.The semi was wedged so tightly that he could not go forward or backward. A fellow trucker came by and told him how he could easily get the semi out from under the bridge.

What did he suggest?

He told Don to let some air out of his tires. This would make the truck lower and allow him to pass through.
