Convoy (1978)

Sam Peckinpah's classic road-movie based around the hit song by C.W. McCall. Long-distance trucker Rubber Duck (Kris Kristofferson) is on the run from corrupt sheriff Lyle Wallace (Ernest Borgnine). He makes a call on his CB radio asking for assistance from other truckers, many of whom have also fallen foul of Wallace in the past. What follows is a massive truckers' convoy, plenty of CB banter, and a whole lot of smashed-up police cars.
