According to the NHTSA, what combination reduces the risk of serious crash-related head injury by 83 percent?

The combination of front air bags and seat belts is significant in enhancing vehicle safety and reducing the likelihood of serious crash-related head injuries. The research conducted by the National Highway Traffic Safety Administration (NHTSA) highlights that using both seat belts and front airbags provides critical protection during a collision.

Seat belts are designed to keep occupants securely in their seats, preventing them from being thrown forward or out of the vehicle during an impact. This containment minimizes the risk of hitting the interior of the vehicle or being ejected from it. Front airbags deploy in the event of a collision, offering an additional layer of protection by cushioning the impact to the occupant's head and upper body.

When used in tandem, seat belts and front airbags work effectively to absorb the forces experienced during a crash. This combination not only reduces the severity of injuries sustained but also significantly decreases the likelihood of fatal injuries. Studies have shown that this pairing can lead to an 83 percent reduction in serious head injuries, making it crucial for all drivers and passengers to buckle up and ensure their vehicles are equipped with functioning airbags.

In contrast, while other options may contribute to safety, they do not provide the same level of effectiveness against serious head injuries as the combination of front airbags with seat belts.
