Air bags — District of Columbia Permit Test
Air bags on the District of Columbia permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Air bags work best when drivers and passengers are secured by lap and shoulder belts and sit as far back as possible; lap and shoulder belts should always be used, even in vehicles with air bags.
An air bag cushions you only from the front, and without a belt you can slide under it or be thrown sideways.
They work best when drivers and passengers are properly secured by lap and shoulder belts and are sitting as far back as possible.
Sit as far from the steering wheel as practical, trying to keep 10-12 inches from the steering wheel hub to your chest.
An air bag bursts out of the wheel very fast, and sitting too close lets it hit you hard before it has finished filling.
Sit as far away from the steering wheel as practical; try to maintain 10-12 inches from the steering wheel hub to chest
Pregnant women should place the lap portion of the safety belt under the abdomen, as low as possible on the hips and across the upper thighs.
A lap belt across the belly presses on the baby in a crash, while the hips and thighs can take the force.

Children age 12 and under should ride buckled up in a rear seat, in a child safety seat or seat belt appropriate for their age and size.
A front air bag opens with enough force to badly hurt a child, so the back seat is the safer place.

Infants should never ride in the front seat of a vehicle with a passenger side air bag.
A rear-facing infant seat puts the baby's head right where the air bag bursts open.

People who must transport infants in rear-facing infant seats in the front passenger seat, or drivers who cannot keep 10 inches between the center of the steering wheel and their breastbone, should consider an air bag on-off switch.
If you cannot keep clear of the air bag, the bag itself becomes the danger, and switching it off can be the safer choice.
People who fall into one of the following risk groups should consider installing an air bag on-off switch.
On the test
Should you wear a seat belt in a car that has air bags?
Yes, air bags work best with belts. An air bag cushions you only from the front, and without a belt you can slide under it or be thrown sideways. DC Driver Manual, p.83: “They work best when drivers and passengers are properly secured by lap and shoulder belts and are sitting as far back as possible.”
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.
