What are air bags designed to do?

Airbags are safety devices designed specifically to protect occupants in a vehicle during a collision. They deploy rapidly in the event of an impact, creating a cushion that helps to absorb forces exerted on the body, reducing the risk of serious injury. The primary purpose of airbags is to prevent the occupants from striking hard interior surfaces, such as the steering wheel, dashboard, or window.

Other options mention functions that are not related to airbags. Increasing vehicle acceleration pertains to the performance aspect of a vehicle, while enhancing fuel efficiency relates to how a vehicle consumes fuel. Ensuring vehicle stability on roads involves aspects of vehicle handling and suspension systems, rather than the safety features provided by airbags. Therefore, the essential role of airbags is clearly to protect occupants during collisions.
