Final answer:
The failure to wear a seatbelt is a primary offense, which enables law enforcement officers to issue citations solely for this violation.
Step-by-step explanation:
The failure of a driver, front seat passenger, and children under the age of 18 to wear a seatbelt is a primary offense in terms of traffic violations. This means that law enforcement officers can stop and cite individuals solely for not wearing their seatbelts, without any other traffic violation being present. It is important to wear seatbelts as they significantly reduce the risk of injury and death in the event of a car accident.
