NASA and the US Department of Commerce Bureau of Public Roads created this color training fiIm in the early 1960s to warn motorists of the dangers of driving too fast on icy or wet pavements. “A skidding car is dangerous,” says the narrator at mark 01:00 following a series of vehicles fishtailing on a variety of slick surfaces. Texture of the pavement, the depth of the surface water, and the inflation of the tires and their treads are just some of the factors that can lead to a spin out. “But only you can recognize the danger signals,” we are cautioned at mark 02:00, “and only you can do something about them.” Some of that knowledge comes from experiments involving aircraft landing on we runways, and see film snippets from various tests showing tires being lifted off wet payment and riding on top of the water, a phenomenon known as hydroplaning (mark 04:12), which causes a driver to lose control. The film includes a series of graphics, beginning at mark 06:05, explaining hydroplaning speeds in a half-inch of water and the corresponding pounds of tire pressure, following by scenes illustrating those speeds. At mark 07:53 the film takes us to NASA’s Wallops Station (later renamed Wallops Flight Facility) in Virginia to witness a series of wet-pavement tests as the narrator explains the braking distances at various speeds. “When pavements are wet, slow down,” the narrator offers as advice at mark 10:46.
