This movie gave a slightly glamorized (and dirty) view into the world of the American trucking industry circa 1973-75. Without crossing over into making a film only truckers and their kin would enjoy, they kept the story and the action fast-paced yet clear as to what is happening unseen. It's not a "CB Fad" movie. A very "Americana" type film which gives a terrific look at the middle American fighting for himself and his ideals. Even though it is a semi-cheesy "B" movie by any standard, the characters are easily related to and the storyline is easy to get involved with, and the action is fun without getting too excessive (gee- a trucker who isn't a gravity defying martial artist!).
Jan-Michael Vincent is at perhaps his best, with Kay Lenz as the perfect naggy whiny trucker's old lady- just cute enough to want to come home to. The musical score is cliché' by today's standards, but dead-on for that time. Some of the old country tunes actually sound pretty good even today (though the twang twang stuff, and the musically reproduced truck horns grew old after while).
