Air bag safety — Tennessee Permit Test
Air bag safety on the Tennessee permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Air bags combined with safety belts are the best protection available; most air bag tragedies can be prevented by also wearing belts.
An unbelted person slides forward into the air bag as it bursts out, which is when it hurts the most.
Air bags combined with safety belts are the best protection currently available in a car, SUV, or truck.
If you have an adjustable steering wheel, keep it tilted down in a level or parallel position.
Tilted up, the wheel aims the air bag at your face and neck instead of your chest.
If you have an adjustable steering wheel, always try to keep it tilted down in a level or parallel position.
Children 12 and under are safer in the back seat of a vehicle.
An air bag is built for an adult and opens with enough force to badly hurt a child.
CHILDREN ages 12 and under are safer in the back seat of a vehicle.
Infants in rear-facing seats should ride in the rear seat, if available, of a vehicle with a passenger-side air bag.
A rear-facing seat puts the back of the baby's head right where the air bag hits.
Infants in rear-facing seats should be placed in the rear seat,
If a child must ride in the front seat with a passenger-side air bag, move the seat back as far as possible and buckle the child properly.
Every inch from the dashboard gives the air bag room to open before it reaches the child.

On the test
What gives the best protection currently available in a car?
Air bags combined with safety belts. An unbelted person slides forward into the air bag as it bursts out, which is when it hurts the most. Tennessee Comprehensive Driver License Manual, p.33: “Air bags combined with safety belts are the best protection currently available in a car, SUV, or truck.”
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.
