Child restraints — Washington Permit Test
Child restraints on the Washington permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Children up to age 2 must ride in a rear-facing car seat.
A small child's neck cannot hold their head in a crash, and facing backward is what spreads the force across the whole seat.
Children up to age 2 must ride in a rear-facing car seat.
Children aged 2 to 4 must ride in a car seat with a rear- or forward-facing harness.
A harness spreads the load over the shoulders and hips, which an adult belt cannot do on a body that size.
Ages 2 to 4 years must ride in a car seat with a rear- or forward-facing harness.
Children aged 4 and older must ride in a car seat or booster until the vehicle lap and shoulder belts fit properly, typically between ages 8 and 12.
Height rather than birthdays decides when the belt lands on bone, so the seat stays until it fits.
Ages 4 and older must ride in a car or booster seat until the vehicle lap and shoulder seat belts fit properly
A child is generally ready for the adult seat belt alone once they are over 4 feet 9 inches tall.
Below that height the shoulder belt crosses the neck, which is the one place it must not be.
Size: Over 4’9”
Children under the age of 13 should never ride in the front seat, because of the airbag.
The airbag is built for an adult's chest, and a child's head is where it arrives.
Airbags are also why children under the age of 13 should never ride in the front seat.
On the test
Until what age must a child ride in a rear-facing car seat?
Up to the age of 2. A small child's neck cannot hold their head in a crash, and facing backward is what spreads the force across the whole seat. Washington State Driver Guide, p.53: “Children up to age 2 must ride in a rear-facing car seat.”
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.
