Systematic traffic checks and increased patrols begin on a high accident freeway. Hoping to determine causes and cures, Dan questions drivers who get too many citations there. One man refuses to accept Dan's safety philosophy. When his license is suspended, his wife drives him to an important business meeting. En route, her eyeglasses break and he takes over at the wheel. Encountering a traffic check, he panics and flees, resulting in a severe accident in which his wife is critically injured. He learns the hard way - and too late - what Dan had earlier tried to impress upon him.
