Thank God for reruns or nobody would know about shows like Highway Patrol.
Broderick Crawford would always end the show with some pithy comment. Like these:
The laws of your community are enforced for your protection ... obey them!
Leave your blood at the Red Cross, not on the highway !
Leave your blood at the Red Cross, or your community blood bank, not on the highway !
The careless driver isn't driving his car, he's aiming it!
It isn't the car that kills, it's the driver!
No matter how new, the safest device in your car is you!
It isn't what you drive, but how you drive that counts!
The clowns at the circus, they're real funny, but on the highway they're murder!
Reckless driving doesn't determine who's right, only who's left!
If you care to drive, drive with care!
Try to be as good a driver as you think you are!
From Wikipedia:
Crawford's heavy drinking increased during the filming of Highway Patrol, eventually resulting in several arrests and stops for driving under the influence of alcohol (DUI), which eventually gained him a suspended driving license. While representing the California Highway Patrol as "Chief Matthews", Crawford was known with considerable embarrassment by the CHP as "Old 502" due to his habit of driving under the influence of alcohol ("Code 502" was the CHP police radio code for drunken driving). According to the show's creator, Guy Daniels, "We got all the dialogue in by noon, or else we wouldn't get it done at all. He [Crawford] would bribe people to bring him booze on the set." The show used their CHP technical advisor, Officer Frank Runyon, to keep the actor sober: "I was told to keep that son of a bitch away from a bottle. I think his license was suspended. Some scenes had to be shot on private roads so that Brod could drive." Eventually the drinking strained the show's relationship with the CHP and Crawford's relationship with ZIV Television Productions.
