Vehicle fire — Arizona Permit Test

Vehicle fire on the Arizona permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

On the test

Why should you shut off the ignition when your car catches fire?

To cut the electrical power. Most car fires start in the wiring, so turning the key off stops feeding the flames. Then people come first, not the car. Arizona Driver License Manual and Customer Service Guide, p.68: “If you have a fire, pull quickly off the road, shut off the ignition to cut electrical power and get all passengers away from the car.”

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.
