A car is equipped with two front air bags. On which seats must safety belts be worn?

In Germany, wearing a seat belt is mandatory on all seats, regardless of whether a car has air bags. Air bags provide additional protection but do not replace the need for seat belts. This applies to both front and rear seats. Therefore, answer 1, “On all seats,” is correct. Always use a seat belt, no matter where you are seated in the vehicle, to maximize safety and comply with the law.
