Seat belts — California Permit Test
Seat belts on the California permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You and your passengers must wear seat belts, and you can get a ticket if you do not.
The belt is what keeps you behind the wheel, where the steering and the brakes are.
You and your passengers must wear seat belts.
If your passenger is under 16 years old, you can get a ticket if they are not wearing their seat belt.
The ticket is written to the driver, because the driver is who decides the car moves.
If your passenger is under 16 years old,
Wearing the lap belt and shoulder harness will increase your chance of survival in most types of collisions, and keeps you in a better position to control the vehicle.
Still being in the seat is the difference between steering out of it and going through the glass.
Wearing the lap belt and shoulder harness of a seat belt will increase your chance of survival in most types of collisions.
Wear the shoulder harness across your shoulder and chest with little or no slack, and never under your arm or behind your back.
Under the arm, the belt loads your ribs instead of the bone that can take it.
Wear the shoulder harness across your shoulder and chest. There should be little to no slack.
Adjust the lap belt so it is snug and lies low across your hips, or you might slide out of the belt in a crash.
Across the hips the belt holds bone. Across the stomach it holds nothing that can take the load.
Adjust the lap belt so that it is snug and lies low across your hips.
If you are pregnant, wear the lap belt as low as possible under your abdomen, with the shoulder strap between your breasts and to the side of the bulge.
Low and to the side keeps the load off the part of you that cannot take it.
If you are pregnant, wear the lap belt as low as possible under your abdomen.
On the test
Who must wear a seat belt in your vehicle?
You and every passenger. The belt is what keeps you behind the wheel, where the steering and the brakes are. California Driver’s Handbook, p.65: “You and your passengers must wear seat belts.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
