Regarding seatbelt use, which statement is NOT true?

The assertion that seatbelts are not necessary if your vehicle has an airbag is not true because airbags are designed to work in conjunction with seatbelts, not as a replacement for them. While airbags provide additional protection during a collision, they do not prevent injuries from being thrown against the vehicle's interior or from the force of the crash itself. Seatbelts are crucial as they secure passengers in their seats, preventing them from being ejected or thrown around inside the vehicle. Thus, the combination of seatbelts and airbags provides the best overall protection during a crash, emphasizing the importance of wearing a seatbelt regardless of the presence of airbags in the vehicle.
