On the test

When should you adjust your seat and mirrors?

Before you start driving. Reaching for a mirror while moving takes your eyes off the road and your hands off the wheel. Iowa Driver's License Manual, p.25: “Adjust the driver’s seat and mirrors before driving to ensure they’re set correctly for you.”

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.
