At what age must all passengers be buckled in all seating positions?

Passengers must be buckled in all seating positions until they reach the age of 16. This requirement ensures the safety of younger passengers who may be more vulnerable in the event of a collision. The law emphasizes the importance of seat belts in protecting all occupants, especially those who are less mature and may not fully understand the risks of not wearing a seatbelt. While older passengers may also benefit from buckling up, the legal focus is on safeguarding those under 16, as studies have shown that their risk of injury decreases significantly when properly secured.
