Violent Road (1958 ) is the precursor of Highway to Hell & Ice Road Truckers, if you're into that sort of thing, i.e. trucks being driven in extreme conditions by happy-go-lucky knights of the road. Stars Efrem Zimbalist, Jr. as George Lawrence, the Cyclone Rocket company scientist in charge of the convoy moving dangerous cargo to the new location over unimproved roads, and Brian Keith, as Mitch Barton, the trucking company's boss.
The Cyclone Rocket Company is a military contractor building missiles for the U.S. Air Force. The company also produces the highly volatile rocket fuel used in the missiles. During a test, a missile explodes. For safety reasons, the government decides to move the company from its current location, near an army base and small town, to a new remote location. However, the plant's dangerous chemicals must be moved by truck to the new location via secondary unpaved roads bypassing all inhabited areas, towns and communities. Moreover, the move must be completed fast and the plant must be operational in three days, in order to maintain its government contract. Three trucks are selected to transport the dangerous rocket fuels. Short on drivers for such a dangerous assignment, the company hires a motley crew of desperate men to drive the trucks through rough terrain to the new location. Each truck has a driver and a helper. Each man is promised five thousand dollars as payment upon delivery...
