Air bags — California Permit Test
Air bags on the California permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Air bags can help keep you safer than a seat belt alone.
They work with the belt rather than instead of it, which is why both are fitted.
Air bags are a valuable safety feature on many vehicles. They can help keep you safer than a seat belt alone.
Ride at least 10 inches from the air bag cover, measured from the center of the steering wheel to your breastbone, as long as you can keep full control of the vehicle.
The bag opens with enormous force in the first few inches, and the distance is what keeps you out of it.
Ride at least 10 inches from the airbag cover, as long as you can maintain full control of your vehicle.
If you cannot safely sit 10 inches away from the air bag, contact your vehicle dealer or manufacturer, who may have advice about moving back from it.
Shorter drivers cannot simply slide the seat back, and the maker knows what else can be done.
Contact your vehicle dealer or manufacturer if you cannot safely sit 10 inches away from the air bag.
Passengers should also sit at least 10 inches away from the passenger-side air bag, and a child seated next to a side air bag may be at risk of serious or fatal injury.
The same force that saves an adult in the seat can injure a child sitting against the door.
should also sit at least 10 inches away from the passenger-side air bag.
On the test
How does an air bag compare with a seat belt?
It adds to what the belt does. They work with the belt rather than instead of it, which is why both are fitted. California Driver’s Handbook, p.67: “Air bags are a valuable safety feature on many vehicles. They can help keep you safer than a seat belt alone.”
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.
