Mopeds are two-wheeled vehicles that, like motorcycles, are less visible, less stable, and more fragile than other types of vehicles. This means that their drivers and passengers are at a higher risk of injury in the event of an accident. For this reason, it is **mandatory** for both the driver and the passenger to always wear a **safety helmet** that is properly fastened and adjusted to the head.

The use of a helmet is crucial to reduce the severity of injuries in the event of accidents, which are more common in urban areas and can be frontal or lateral. The lack of a helmet significantly increases the consequences of these accidents.

Therefore, the regulations require that moped drivers wear a helmet **at all times**, without exceptions, to ensure their safety at all times.
