Most of the safety features in a car increase the impact time and consequently reduce the impact force. Seat Belts restrain the passenger and stop the passenger from crashing into the dashboard, front seats or the windscreen or any part of the car frame when the car suddenly stops.airbags act as a cushion to spread the impact force and increase the impact time to reduces the impact force.Crumple Zones around the engine compartment allow the car body to deform and be crushed, increasing the impact time in order to decrease the impact force.collapsible steering wheel. If the driver crashed into the steering wheel, the impact force collapses the steering wheel reducing the force on the driver by increasing the impact time.vehicle bumpersdeform a little with low-speed impact, increasing the impact time and therefore reducing the impact force.
