Who is required to wear a seat belt in a moving motor vehicle?

Under state law, the driver and all passengers of a passenger vehicle must wear a seat belt. The failure of a driver, front seat passenger, or child under age 18 to wear a seat belt is a primary offense. The driver is responsible for all passengers under age 18. Under a secondary law, all unbuckled back seat occupants 18 years of age and older may be issued a summons if the vehicle has been stopped for a different reason.
