Which is more important in saving lives a seat belt an air bag or anti lock brakes?

While all three safety features contribute to vehicle safety, seat belts are generally considered the most important for saving lives. They are effective in preventing ejection from the vehicle and minimizing injury during a collision. Airbags provide additional protection by cushioning occupants during a crash, but they work best when seat belts are also used. Anti-lock brakes enhance vehicle control during hard braking, but they do not prevent collisions; thus, seat belts remain the primary life-saving feature.
