Who must ensure that all passengers are secured with seat belts in a vehicle in Italy?

The responsibility for ensuring that all passengers are secured with seat belts in a vehicle in Italy rests with the driver. This means that it is the driver's duty to ensure that all occupants of the vehicle are buckled up before driving. This regulation is in place to enhance safety for everyone in the vehicle as well as to reduce the risk of injury in the event of an accident.

While each passenger is expected to wear their seat belt, it is the driver who is held accountable for the safety of everyone in the vehicle, making it crucial for them to check that all passengers are properly secured. This not only reflects a legal obligation but also promotes a culture of safety on the roads.
