Crash Test Dummies are anthropomorphic figures used in vehicle safety testing to simulate the effects of car accidents on human bodies. They are designed to represent different sizes and weights, allowing researchers to assess how various body types respond to collisions. Equipped with sensors, these dummies measure forces and impacts during crash tests, providing valuable data for improving vehicle safety features. The use of Crash Test Dummies began in the 1940s, and they have evolved significantly over the years. Modern dummies are highly sophisticated, featuring advanced technology that helps engineers develop safer cars and reduce injuries in real-world accidents.
