Driving in and exiting a roundabout — Arizona Permit Test

Driving in and exiting a roundabout on the Arizona permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

On the test

Once you are inside a roundabout, what should you not do?

Come to a stop. The cars behind you in the circle do not expect a stop and will run into you. Arizona Driver License Manual and Customer Service Guide, p.28: “Once inside, do not stop. Follow directions on signs or pavement markings about which lane to use.”

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.
