Trivia: Although many realistic freeway numbers and exits mentioned over the 2-way radio are real, they were not used in the show. An unused section of the 210 freeway (close to the 118 freeway) in the San Fernando Valley that wasn't quite open to the public yet, was the location nearly always shown on the show representing whatever location is mentioned. If you see many episodes, you can see the same section of freeway always shown.
Trivia: According to the credits, this episode was written by a "James McAteer". However,"James McAteer" is actually a pseudonym for well-known TV scriptwriter P J Hammond (who, amongst many other things, created and wrote the strange sci-fi series "Sapphire and Steel"). Apparently Hammond did not care for certain "alterations" made to his script (rewrites by the Series' creator Brian Clemens) and asked that his name be removed from it.
