Devil Take Us 1952

A motorcycle cop buys a used car to take his family on vacation to the East Coast. Minor car trouble along the way causes him to meet first a reckless driver, and then a highway patrolman who shares stories of bad drivers with him. Various dangers of careless driving - both fictional and real - are depicted as the patrolman continues on the job, later crossing paths with the reckless driver again. When the police officer makes the return trip from his vacation, he finds that the situation has changed in a surprising way.
