Safety belt crash forces — Alaska Permit Test
Safety belt crash forces on the Alaska permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A loose belt does not mean the belt is inoperative: belts made after 1974 use an inertia reel that locks when the car slows down too quickly.
Drivers who think a slack belt is broken may stop wearing it, when it is built to lock the instant a crash begins.
Loose belts do not indicate that the belts are inoperative.
In a 30-mph head-on collision, objects including passengers can be thrown forward with a force equal to 30 times their own weight.
Even a slow crash turns anything loose in the car, and anyone unbelted, into something heavy flying forward.
Under these conditions, objects (including passengers) can be thrown forward with a force equal to 30 times their own weight.
On the test
A safety belt in a car built after 1974 feels loose. What does that mean?
It still locks if the car slows fast. Drivers who think a slack belt is broken may stop wearing it, when it is built to lock the instant a crash begins. Alaska Driver Manual, p.26: “Loose belts do not indicate that the belts are inoperative.”
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.
What it costs
- One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
- Free to start: a 10-question test and the first section of cards. No sign-up and no account.
- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
