Drivers must use their seat belt:

  1. Unless they are driving a vehicle built before 1978.
  2. Unless they are driving a limousine.
  3. And failure to do so will result in a traffic ticket. ✓

Answer: C. And failure to do so will result in a traffic ticket.

Drivers must use their seat belt, and failing to do so can result in a traffic ticket.

Why this is the answer

The handbook says you and your passengers must wear seat belts, and it says you can get a ticket if you do not. It also says a ticket is possible when a passenger under 16 is unbuckled. That wording makes the seat belt requirement something enforced by citation, not just advice. The passages give no exception for older vehicles or limousines, so the choice about a traffic ticket is the one supported by the handbook.

Why the other answers are wrong

Remember it

Remember it as a simple deal: belts on, or you can be ticketed.
