Child passenger safety — Minnesota Permit Test
Child passenger safety on the Minnesota permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Do not use a child safety seat that has been in a crash.
The crash may have cracked the shell where nothing shows, and it only has to fail once.
Do not use a safety seat that has been in a crash.
Child restraint systems expire six years from the date of manufacture unless the seat gives its own date.
Plastic gets brittle and standards move on, so an old seat is not the seat it was.
Child restraint systems expire six years from the date of manufacture.
Never place a rear-facing infant seat in front of an active airbag.
The bag fires at the speed of an explosion into the back of the seat, which is where the baby’s head is.
Never place rear-facing infant seats in front of an active airbag.
Do not hold a child on a passenger’s lap while the vehicle is moving.

Children should not ride in the cargo area of a truck or station wagon.
There is no belt, no seat and nothing between them and the road if the tailgate opens.

On the test
What should be done with a car seat after a crash?
It should not be used again. The crash may have cracked the shell where nothing shows, and it only has to fail once. Minnesota Driver’s Manual, p.38: “Do not use a safety seat that has been in a crash.”
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.
