How Arizona's written test works

Arizona's written knowledge test is a computer-based exam you take at an Arizona Department of Transportation (ADOT) office. The test has 50 multiple-choice questions, and you need to answer at least 40 correctly to pass — that's 80 percent. You get one attempt per visit, and if you don't pass, you can retake it the same day or come back another time.

The questions come from the Arizona Driver License Manual, which ADOT publishes free online and at every ADOT office. The test covers road signs, right-of-way rules, speed limits, parking, seat belt laws, and how to handle hazards. Arizona also tests on impaired driving laws and what to do if you're pulled over.

You'll sit at a computer terminal in a testing booth. The exam is untimed, so you can take as long as you need to read each question and choose your answer. Once you finish all 50 questions, the computer scores your test when ready and tells you whether you passed or failed.

What the test covers

The Arizona written test focuses on practical road knowledge you'll need to drive safely. Expect questions about traffic signs and what they mean — stop signs, yield signs, warning signs, and regulatory signs. You'll see questions about right-of-way rules: who goes first at a four-way stop, how to handle a left turn, and what to do when an emergency vehicle approaches.

Arizona tests heavily on speed limits and when they change. You need to know the default speed limit on residential streets (15 mph in some areas), on highways (65 mph unless posted otherwise), and how to adjust your speed in bad weather or heavy traffic. The test also covers parking rules, including where you cannot park and what the different parking signs mean.

Impaired driving is a major topic. Questions ask about the legal blood alcohol content (BAC) limit for drivers under 21 (zero tolerance in Arizona), for drivers 21 and older (0.08 percent), and for commercial drivers (0.04 percent). You'll answer questions about how alcohol affects your ability to drive and what happens if you refuse a breath or blood test.

The test includes questions about seat belts, child safety seats, and distracted driving. Arizona also tests your knowledge of what to do if you're pulled over — where to pull over, what documents to have ready, and your rights during a traffic stop.

How to study for the Arizona test

The Arizona Driver License Manual is your primary study resource. ADOT publishes it free on its website, and you can read it as a PDF or read it online. The manual is organized by topic, so you can study one section at a time. Every question on the test comes from information in this manual, so studying it thoroughly is the most direct path to passing.

Read the manual section by section and take notes on topics that are new to you or that you find confusing. Pay special attention to the sections on signs, right-of-way, speed limits, and impaired driving — these topics appear frequently on the test. After you've read through the manual once, go back and reread the sections you found hardest.

ADOT does not publish official practice tests, but many third-party websites offer Arizona-specific practice questions. These can help you get used to the computer format and the style of questions, but remember that only the official manual guarantees accuracy. If you find a practice question that contradicts the manual, trust the manual.

Study in short sessions over several days rather than cramming the night before. This helps information stick in your memory. If you have a friend or family member who has passed the Arizona test, ask them which topics they found trickiest — that's often where people lose points.

What to bring to your test appointment

Bring a valid form of identification. ADOT accepts a passport, a birth certificate with a photo ID, a military ID, or a tribal ID. If you're under 18, you may need additional documents — check with your local ADOT office about what counts as valid ID for your age.

You'll also need to show proof of your Social Security number. A Social Security card works, but so does a tax return, a W-2 form, or a 1099 form. If you don't have a Social Security number, bring a letter from the Social Security Administration explaining why.

Bring proof of your Arizona residency if you're explore for an Arizona license for the first time. A utility bill, a lease, or a bank statement with your name and current address works. You do not need to bring the Driver License Manual to your test — ADOT provides everything you need at the testing station.

What happens if you fail

If you score below 80 percent, you fail the test and do not move forward to the road test. You can retake the written test when ready — you don't have to wait days or weeks. Many people retake it the same day they failed, after spending an hour or two reviewing the manual sections they found hardest.

There is no limit to how many times you can retake the written test in Arizona. Each attempt costs the same fee, so budget for multiple test fees if you think you might need more than one try. Most people pass on their second attempt after focused study on their weak areas.

When you retake the test, you'll get a different set of 50 questions, but they'll cover the same topics and come from the same manual. Study the same way you did before, but this time focus on the specific areas where you lost points on your first attempt.

Testing in a language other than English

Arizona offers the written test in Spanish. If Spanish is your primary language, you can request a Spanish-language test when you schedule your appointment or when you arrive at the ADOT office. The Spanish version covers exactly the same material as the English version, and you need the same 80 percent score to pass.

ADOT also publishes the Driver License Manual in Spanish. You can read it from the ADOT website or pick up a printed copy at any ADOT office. Studying from the Spanish manual ensures that the language you study matches the language you'll see on the test.

After you pass the written test

Once you pass, you're cleared to schedule your road test with an ADOT examiner. The road test is the next step toward getting your Arizona driver license. You'll drive a vehicle (usually your own or a family member's) while an examiner watches and scores your driving skills.

Between passing the written test and taking the road test, keep studying the manual. The road test covers practical process of the rules you learned in writing — things like proper lane positioning, smooth braking, and correct turning technique. Many people study the manual again while waiting for their road test appointment.

Frequently Asked Questions

Can I take the Arizona written test online from home?

No. Arizona requires you to take the written test in person at an ADOT office on a computer provided by ADOT. This ensures the test is proctored and that your identity is verified. You cannot take it remotely or on your own device.

How long does the written test take?

The test itself is untimed, so it takes as long as you need to read and answer 50 questions. Most people finish in 30 to 45 minutes. The entire visit to the ADOT office, including check-in and waiting, usually takes 1 to 2 hours depending on how busy the office is.

What score do I need to pass the Arizona written test?

You need to answer at least 40 out of 50 questions correctly, which equals 80 percent. One wrong answer brings you to 98 percent, two wrong answers to 96 percent, and so on. You cannot pass with 39 correct answers.

Can I use the manual during the test?

No. The written test is closed-book. You cannot bring the manual, notes, or any other study materials into the testing booth. You must answer all questions from memory based on what you studied beforehand.

What if I don't pass on my first try?

You can retake the test the same day or schedule another appointment for a later date. There is no waiting period between attempts in Arizona. Each retake costs the same fee as your first attempt. Focus your next study session on the topics where you struggled.
