Passive safety features are design elements in vehicles that help protect occupants during a crash without requiring any action from them. These features include seat belts, airbags, and the vehicle's structural integrity, which absorbs and dissipates energy during an impact. Their primary goal is to minimize injury by providing a safer environment in the event of an accident. Another important aspect of passive safety is the use of crumple zones, which are areas of a vehicle designed to deform and absorb energy during a collision. This helps to reduce the force transferred to passengers. Overall, passive safety features work together to enhance the protection of everyone inside the vehicle.
