Highway Patrol (1955)

Classic 50s cop show, starring the gruff and often inebriated Oscar winner Broderick Crawford, playing the role of Dan Mathews, whose rank was never quite the same from one show to the next. Catch phrase was 10-4. Great 50s finny cars. Stars who got their start on this show included Clint Eastwood, Barbara Eden, Leonard Nimoy (two appearances). Gene Roddenberry wrote several episodes under a pseudonym.
