Trying to find name of 80's trucking movie
I am trying to find the name of a movie from the 80's, my husband and best friend both have seen this movie and can't remember tha name. They say it is about a father and son who are both driving a semi-truck, someone throws a cynder block off the top of a bridge and it goes through the windshield of the father's truck, he gets hurt and goes to hospital where he dies from the injuries received from the block. The son then builds a "Monster" semi (like a monster truck only the semi version) and goes after the people who threw the block and killed his father. Hope someone out there can help me out and remember the name. Thanks!
