In Maine, what is the requirement for wearing seatbelts?

In Maine, the law requires that all passengers must wear seat belts, which aligns with the correct answer. This regulation is designed to enhance safety for everyone in the vehicle, not just the drivers and front-seat passengers. By ensuring that all passengers are secured with seat belts, the risk of injury during a crash is significantly reduced. Seat belts are one of the most effective means of protecting individuals in the event of an accident, as they help to keep occupants safely restrained within the vehicle.

The other options misrepresent the law. For instance, suggesting that only the driver or just front seat passengers need to buckle up would leave many individuals at risk, particularly those in the back seat. The law covers all occupants regardless of age or seating position, reinforcing the importance of universal seatbelt use for maximizing safety on the roads.
