A crash test is a controlled experiment in which a vehicle or other object is subjected to a simulated collision in order to assess its safety and structural integrity. This test involves intentionally crashing the object at various speeds and angles, using specialized equipment and dummies to measure the impact and potential injuries. The results of a crash test are used to evaluate the effectiveness of safety features and to improve the overall design and construction of vehicles and other products. Crash tests are an essential part of ensuring the safety of drivers, passengers, and pedestrians on the road.
