Violent Road (1958), a review:

Mr. Nelson (Ed Prentiss) is in a heck of a tough spot: a rocket test containing his fuel veered off-course and claimed the lives of innocent townsfolk. The least they could do is relocate. The problem is that one does not simply relocate rocket fuel; it has to be transported by land, in its three base ingredients. To make matters worse, the only route they’re permitted to drive through are old, treacherous back roads. Truck driver Mitch Barton (Brian Keith) knows that Mr. Nelson needs drivers ASAP, even gambling that he’ll be taken in even though he wasn’t exactly sent there by another company (he got fired). Mr. Nelson takes the risk of hiring Mitch, briefs him on the cargo and route, then sets him to recruit drivers and assistants for the three trucks.

Convoy (1978), a review:

In the Southwestern highways, a convoy of paramount proportions have garnered national interest. When government officials ask around in rolling interviews as to why, the answers given vary as much as the individuals taking part! So who is spearheading the effort? That would be Martin “Rubber Duck” Penwald (Kris Kristofferson). But the truth is, all he wanted was to get out of Arizona. Why? Because he wouldn’t take the abuse dished out by corrupt Sheriff “Dirty” Lyle “Cottonmouth” Wallace (Ernest Borgnine) against two of his trucking friends Bobby “Love Machine” “Pig Pen” (Burt Young) and “Spider” Mike (Franklyn Ajaye). Having beaten the crap out of him and his fellow officers, the trucking trio made a bee-line out of the state, followed by more truckers that aided and abetted them.
