What the Arizona DMV written test covers

Arizona's written knowledge test has 50 questions, and you need to answer at least 40 correctly to pass. The test covers Arizona traffic laws, road signs, safe driving practices, and what to do in emergencies. You take it on a computer at an Arizona Department of Transportation (ADOT) office, and you get your score when ready.

The questions come from the Arizona Driver License Manual, which ADOT publishes free online. Every question on the test is based on that manual — nothing is a trick or outside what's in there. You can read the manual before you test, and many people do.

The test is offered in English and Spanish. If you need the test in another language, contact your local ADOT office to ask what's available in your area.

Key Takeaways

  • Arizona's written test has 50 questions; you must answer 40 correctly to pass, and you get your score the same day.
  • Every question comes from the Arizona Driver License Manual, which you can read free on the ADOT website before you test.
  • You take the test on a computer at an ADOT office, and you can retake it the same day if you fail.
  • Road signs, Arizona traffic laws, and safe driving practices make up the bulk of the test content.

What documents you need to bring

Bring a valid form of ID — a passport, tribal ID, military ID, or an out-of-state driver license all work. You also need proof of residency, which can be a utility bill, lease, mortgage statement, or bank statement with your name and Arizona address on it. The document must be dated within the last 60 days.

If you are under 18, bring your birth certificate or passport and a parent or guardian's ID. You also need a completed process for Arizona Driver License or Instruction Permit (Form 40-0001), which you can fill out at the ADOT office or read and bring completed.

Bring your Social Security number or a document that shows it. If you don't have a Social Security number, bring a letter from the Social Security Administration saying you are not may be able to access.

How to prepare for the test

read or request the Arizona Driver License Manual from the ADOT website. Read the sections on traffic laws, right-of-way rules, speed limits, parking, and what different road signs mean. These topics appear on almost every test. Spend extra time on sections about intersections, pedestrians, and what to do when you see a school bus.

Take the practice test on the ADOT website. It has questions in the same format as the real test and covers the same topics. You can take it as many times as you want, and it's free. If you miss questions, go back to the manual and reread those sections.

Some people study for a few days; others study for a week or two. How long you need depends on how familiar you already are with Arizona roads and laws. If you learned to drive in another state, allow more time to learn Arizona's specific rules.

Where to take the test in Arizona

ADOT has offices in every county. Find the office nearest you on the ADOT website by entering your city or zip code. You do not need an appointment at most offices, but some locations ask you to book a time slot online. Check your local office's website before you go.

Hours vary by location. Most offices are open Monday through Friday during business hours, and some are open on Saturday mornings. A few offices have extended evening hours. Call ahead or check online if you are planning to go outside normal business hours.

The test takes about 15 to 20 minutes once you sit down at the computer. You may wait longer if the office is busy, so arrive early or go during a slower time of day if you can.

What happens if you fail the test

You can retake the test the same day at most ADOT offices, though some locations may ask you to come back another time. There is no waiting period between attempts in Arizona. You pay the test fee again each time you take it.

If you fail, ask the ADOT staff which topics you missed most. Go back to the manual, study those sections, and try again. Most people pass on the second or third attempt if they study between tests.

You have a limited time to pass the written test before your instruction permit expires. An instruction permit is usually valid for one year, so plan to pass the written test and then take the driving test before that year is up.

The difference between the written test and the driving test

The written test is only the first step. After you pass it, you get an instruction permit, which lets you drive with a licensed adult in the car. You then take a separate driving test with an ADOT examiner, who watches you drive and scores your ability to handle the car, follow traffic laws, and respond to road conditions.

The driving test is not based on the manual — it's based on how you actually drive. You need to show you can start the car, steer, brake, turn, park, and follow traffic laws without the examiner telling you what to do. The written test only checks that you know the rules; the driving test checks that you can follow them.

Frequently Asked Questions

Can I use my phone or notes during the test?

No. The test is proctored, meaning an ADOT staff member watches you while you take it. You cannot use your phone, notes, or any other materials. You can only use the computer in front of you.

What if I fail the written test multiple times?

You can retake it as many times as you need before your instruction permit expires. Each attempt costs the test fee. If your permit expires before you pass, you have to start over and pay for a new permit.

Is the test the same every time I take it?

No. The questions are different each time, but they all come from the same Arizona Driver License Manual. If you study the manual thoroughly, you will be ready for any version of the test.

What if I need the test in a language other than English or Spanish?

Call your local ADOT office and ask what languages are available. Some offices can arrange tests in other languages, but you may need to schedule in advance or travel to a different location.

How long is the instruction permit valid after I pass the written test?

An instruction permit is usually valid for one year from the date you get it. You must pass the driving test and get your full license before the permit expires, or you will have to retake the written test.
