Air bags and belts — Louisiana Permit Test
Air bags and belts on the Louisiana permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
An air bag inflates fast during a head-on or nearly head-on collision.
Air bags are built for front crashes, when your body is thrown toward the wheel and dash.
An airbag is a flexible membrane that inflates rapidly with air or another gas during a head on or nearly head on collision.
Air bags are a Supplementary Restraint System; your safety belt is your primary restraint.
To get the full help of an air bag, your belt must first hold you in the right spot.
Your safety belt is your primary restraint and, for you to get the best protection with your air bags, you need to use your safety belt properly.
Air bags do not deploy when you are rear-ended by another car.
In a crash from behind, only your belt and headrest keep you safe, since the bag stays packed away.
Air bags do not deploy when you are rear-ended by another car.
On the test
In what kind of crash does a front air bag inflate?
A head-on or nearly head-on crash. Air bags are built for front crashes, when your body is thrown toward the wheel and dash. Class D & E Driver's Guide, p.41: “An airbag is a flexible membrane that inflates rapidly with air or another gas during a head on or nearly head on collision.”
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.
