Are air bags always helpful in a crash?

Airbags can significantly enhance safety during a crash by providing a cushion that reduces the risk of severe injury to passengers. However, their effectiveness can depend on various factors, such as the speed of the collision, the position of the occupants, and whether seat belts are worn. In some cases, airbags may cause injuries, particularly to smaller individuals or children who are not properly restrained. Overall, while airbags are beneficial, they are most effective when used in conjunction with seat belts.
