Safety features in vehicles such as ABS, crumple zones, seatbelts, airbags, side impact bars, strengthened windscreens, padded dashboards, and headrests are designed to prevent injuries during car crashes. ABS allows wheels to interact with the road surface during braking to prevent skidding. Crumple zones and seatbelts absorb crash forces to divert them away from passengers. Airbags cushion impacts, while side impact bars, strengthened windscreens, padded dashboards, and headrests protect specific body parts from damage. These safety features are intended to reduce crash forces and prevent injuries.

- 2. Learning outcomes Describe the importance of safety features in vehicles Understand the components of safety features in vehicles Labeled the components of safety features in vehicles
- 3. Introduction Cars today are much safer to travel in than cars ten or twenty years ago. As a result of crash tests, designs have changed and are still changing.
- 4. What can we do to prevent injuries in car crash?
- 5. Anti-braking system (ABS) Allows the wheels to continue interacting with the road surface as directed by driver while braking, preventing the wheels from skidding.
- 6. Crumple Zones Crumple zones were first introduced in 1959. Easily crushed to increase the time interval of impact. In doing so, the force of the collision would be diverted away from the passenger's compartment, thereby keeping him or her from serious injury.
- 7. Seat belts The seat belt was introduced by Nash Motors in 1949. Seat belts work in the same principle as crumple zones. Help to hold the passengers in their position during collision and prevent them from being thrown forward due to inertia.
- 8. Airbags Airbags help cushion the impact, reducing your momentum more slowly so that the force is less. Airbags are intended to be used as a supplementary device to the seatbelt.
- 9. Side Impact Bar Absorbs impact to prevent damage to the car Longer the time of impact and hence will reduce the impulsive force
- 10. Windscreen Made of shatter-proof glass so that it will not break into pieces easily This will reduce injuries caused by the pieces of glass which scatter during collision
- 11. Padded Dashboard Increase time interval of collision so that the impulsive force produced is reduced
- 12. Headrest Prevent the passengers from suffering severe neck injuries
