Vehicle testing is the process of evaluating a vehicle's performance, safety, and reliability. This includes checking various systems like the engine, brakes, and tires to ensure they function properly. Testing helps identify any issues that could affect the vehicle's operation, making it safer for drivers and passengers. During vehicle testing, professionals often use specialized equipment and follow strict guidelines set by organizations like the National Highway Traffic Safety Administration (NHTSA). These tests can include crash tests, emissions testing, and durability assessments. The results help manufacturers improve their designs and ensure that vehicles meet safety standards before they hit the roads.
