Legendary “shock” driving safety film featuring numerous scenes of mutilated cars and injured/dead people and a voice over lacking in compassion.

Produced in cooperation with the Ohio State Highway Patrol and shown to millions of young drivers for over 40 years.

Signal 30 is just one of several Driver’s Education films produced by Highway Safety Films, filmed at actual auto accident scenes and consisting largely of color closeups of mangled accident victims.

Other titles in the series included Carrier or Killer, Highways of Agony, Mechanized Death and Wheels of Tragedy. There were also imitators; Death on the Highway is probably the most (in)famous.
