This is the only "Highway Patrol" episode in which Dan Mathews is actually referred to as "Chief" by one of his subordinates. The character was familiarly referred to as "Chief" Dan Mathews by fans of the series, but he was never given an official title on the show. Different Highway Patrol and State Police agencies have different organizational structures and the production company (ZIV Television Programs, Inc.) attempted to avoid any references that would make it appear that any particular structure was being favored. When necessary, the show's narration referred to Dan's function as "the head of the Highway Patrol", and the nameplate on his desk simply read "Dan Mathews".
What the title of this episode (Statute of Limitations) refers to is a law that sets the maximum amount of time that parties involved in a dispute have to initiate legal proceedings from the date of an alleged offense, whether civil or criminal. However, the length of time the statute allows for a victim to bring legal action against the suspected wrong-doer can vary from one jurisdiction to another and the nature of the offense.
Suspect Eddie Beekman is driving a 1956 Chrysler Windsor Convertible Coupe. It was equipped with a 331 cu.in. "Spitfire" V8, rated at 225hp. Its "PowerFlite" Transmission was push button operated.
