If a law enforcement officer stops a vehicle for a traffic violation and finds a front-seat passenger 18 years of age or older not wearing a safety belt, a safety belt violation will be charged to:
The front-seat passenger
Neither the driver nor the front-seat passenger
Both the driver and the front-seat passenger
The driver

Safety belt violation would be charged to the front seat passenger.

Option A.

Explanation:

Essential safety belt laws permit law implementation officials to ticket a driver or traveler for not wearing a safety belt, with no other traffic offense occurring. 11 states incorporate back seats as auxiliary implementation. Five of these are states with essential safety belt laws for front seat tenants.

In 15 of the 50 expresses, the safety belt law is viewed as an optional offense, which implies that a cop can't stop and ticket a driver for the sole offense of not wearing a safety belt. (One special case to this is Colorado, where kids not appropriately limited is an essential offense and brings an a lot bigger fine.)
