a life-sized model of a human used in tests to see how safe cars are in accidents
A crash test dummy is a life-size model used in vehicle crash tests to simulate how a human body would react during a collision. These dummies are equipped with sensors and instruments that measure things like force, pressure, and movement. They are made from materials that mimic human bones and tissues, allowing engineers to study the effects of crashes on different parts of the body. By using crash test dummies, manufacturers can improve vehicle safety features, such as seat belts, airbags, and car structure, to better protect real people in the event of an accident.
