This ad campaign with the crashing toasting glasses began airing in 1983 and was on TV seemingly forever (at least until the 1990s). Juxtaposing the slow-motion toasting glasses to the sound of skidding tyres and crashing cars made quite an impression on me, and seemingly everyone else. It was very effective in reducing the number of drunk drivers. The lines "Drinking & Driving Can Kill A Friendship" and "Friends Don't Let Friends Drive Drunk." were used throughout.
