In terms of vehicle safety, what is prompted by the absence of a functioning airbag?

The absence of a functioning airbag significantly increases the risk of injury in an accident. Airbags are designed to deploy at the moment of a collision, providing a crucial cushioning effect that mitigates the impact on occupants. When an airbag fails to operate as intended, the individuals inside the vehicle are left unprotected against the forces of the crash, leading to a higher likelihood of severe injuries or fatalities.

Other options, such as enhanced vehicle performance, lower insurance premiums, and improved fuel efficiency, do not directly relate to the safety benefits provided by airbags. In fact, a vehicle without functional safety features like airbags may result in higher insurance rates due to the increased risk associated with driving an unsafe vehicle. This context underscores why the correct focus is on the heightened risk of injury when airbags are absent.
