A seat belt should be adjusted so that it:
- Is loose.
- Is buckled snugly across your hip bones and lower abdomen. ✓
- Is hidden beneath the seat.
- Keeps the seat belt buzzer or light from operating.
Answer: B. Is buckled snugly across your hip bones and lower abdomen.
A seat belt should be buckled snugly so the lap belt sits around your hips, which is what the choice describing a snug fit across your hip bones and lower abdomen means.
Why this is the answer
The handbook tells you to wear both the lap belt and the shoulder belt, and to put the lap belt around your hips with the shoulder belt across your chest. It also warns that a belt tucked behind you will not work. A snug lap belt across the hips keeps you from being ejected, from being thrown into other passengers, the steering wheel or windshield, and keeps you behind the wheel where you can control the car.
Why the other answers are wrong
- A. Is loose. — A loose belt is not what the handbook describes; it says to wear the lap belt around your hips and the shoulder belt across your chest so the belt can do its job.
- C. Is hidden beneath the seat. — Hiding the belt under the seat is not a fit adjustment at all, and the handbook says a belt tucked behind you will not work.
- D. Keeps the seat belt buzzer or light from operating. — The handbook never mentions silencing a buzzer or light; it frames the belt as protection in a crash, not as a way to stop a warning.
Remember it
Picture the lap belt low and firm across your hip bones, with the shoulder strap over your chest, not behind you.
