If you are riding in a vehicle equipped with a lap belt and a separate shoulder belt, you are:

1. Only required to use the lap belt.
2. Required to use both the lap and shoulder belts. ✓
3. Only required to use the shoulder belt.

Answer: B. Required to use both the lap and shoulder belts.

You are required to use both the lap belt and the shoulder belt when your vehicle has them as separate belts.

Why this is the answer

The California handbook tells drivers and passengers to wear seat belts and describes using the lap belt and shoulder harness together. It says to put the shoulder harness across your shoulder and chest, with little or no slack, and not tucked under the arm or behind the back. It also says to adjust the lap belt snug and low across your hips. Those instructions treat the two belts as parts of one properly worn seat belt, which supports the answer that both are required.

Why the other answers are wrong

• A. Only required to use the lap belt. — Using only the lap belt leaves out the shoulder harness that the handbook says to wear across your shoulder and chest.
• C. Only required to use the shoulder belt. — Using only the shoulder belt ignores the lap belt, which the handbook says should be snug and low across your hips.

Remember it

Think of the two belts as a team: shoulder across the chest, lap low on the hips.
