Headlights
Headlihts prevent accidents by lighting up by illuminating the roadway to allow the driver to avoid hazards. -
ABS Brakes
ABS Brakes work by periodically releasing pressure to the wheels so that the wheels don't stop spinning. When the wheels turn, they are applying a force to the ground which pushes against the direction of the car's motion slowing it down. -
3 point Seat Belt
Seat Belts work by stopping the passenger from flying out of their seats. Unless the objects inside the car are restrained they will continue moving at whatever speed the car is traveling even if the car is stopped by a crash. Seat-belts can reduce the impact of a passenger to one-fifth of the impact suffered by the body of the car thus reducing damage caused in an incident -
Airbags
Airbags provide a cushion which allows people to decelerate relatively slowly during a collision, instead of catastrophically slamming into the windshield or dashboard or steering wheel. They allow the collision to take place over a relatively long time (so the total stopping force is smaller), and spread out over a larger area of the body (so the pressure is lower) both of which result in fewer fractures and other injuries. (similar to seat belts) -
Electronic Stability Control (ESC)
Electronic Stability Control is some what similar to ABS brakes in how they work. It applies the brakes to individual front or rear wheels and/or reduces excess engine power as needed to help correct under-steer or overs-teer conditions. ESC also controls all-speed traction control, by sensing drive-wheel slip under acceleration, and then individually braking the slipping wheel or wheels, and/or reducing excess engine power, until control is regained.
