When it comes to preventing whiplash, the best safety feature among the options provided is b headrest. While seatbelts and airbags are crucial for overall safety during a collision, headrests play a pivotal role specifically in preventing neck injuries such as whiplash.
Whiplash occurs when the head is suddenly jerked forward and then backward, often during rear-end collisions. A properly adjusted headrest can mitigate the force of this movement by supporting the head and neck, reducing the risk of injury. It should be positioned close to the back of the head and at an appropriate height to be effective.
While seatbelts help secure the body in place and airbags provide cushioning during a collision, they do not directly support the head and neck in the same way. Therefore, for specific prevention of whiplash injuries, ensuring your headrest is properly adjusted is key.
