The Iowa permit test has 35 questions
The Iowa written permit test contains 35 multiple-choice questions. You must answer at least 28 questions correctly to pass, which is a score of 80 percent. The test covers Iowa traffic laws, road signs, safe driving practices, and what to do in emergency situations on the road.
The Iowa Department of Transportation administers the test at your local driver's license station. You take it on a computer at the testing station — you cannot take it online from home. The test itself usually takes 20 to 30 minutes to complete, depending on how quickly you read and answer each question.

What the test covers
All 35 questions come directly from material in the Iowa Driver's Manual, which you can read online at the Iowa Department of Transportation website or pick up in print at any driver's license station. The questions test your knowledge of Iowa traffic laws, not your driving ability — that comes later during the road test.
The test includes questions about road signs and what they mean, right-of-way rules at intersections and roundabouts, speed limits and when they change, parking rules, what to do if you see emergency vehicles, how to handle bad weather or night driving, and the rules for sharing the road with pedestrians and cyclists. Some questions ask about the consequences of breaking traffic laws, like fines or license suspension.
Iowa also asks questions about alcohol and driving, seat belt use, and distracted driving. A few questions cover what to do if you are in a crash — whether to move your vehicle, when to call police, and what information to exchange with the other driver.
How the test is scored
The computer scores your test when ready after you finish. You see your score right away at the testing station. If you pass with 28 or more correct answers, you receive your permit on the spot — the station prints it for you before you leave.
If you do not pass, you can usually retake the test the same day at many stations, though some locations may ask you to come back another day. There is no waiting period between attempts in Iowa. Each time you retake the test, you pay the testing fee again.
How to prepare for the 35 questions
The Iowa Department of Transportation publishes the Driver's Manual free online, and that manual contains all the information you need to answer the 35 questions correctly. Read through the manual section by section — it is organized by topic, so you can focus on areas where you feel less confident.
Many people find it helpful to read the manual once all the way through, then go back and study the sections that seemed hardest. Pay special attention to road signs, because the test includes several questions that show you a sign and ask what it means. The manual has pictures of every sign you need to know.
Practice tests are available online through third-party websites, though these are not official Iowa tests. They can help you get used to the format and the types of questions, but remember that only the official Iowa Department of Transportation test counts toward your permit.
When you can take the test
You must be at least 14 years old to take the Iowa permit test. You also need to bring a valid form of identification — a birth certificate, passport, or state ID card all work. If you are under 18, you may need a parent or guardian to sign consent forms, depending on your age.
Driver's license stations are open during regular business hours, usually Monday through Friday during the day. Some stations have extended hours or Saturday hours, but this varies by location. Check the Iowa Department of Transportation website to find the station nearest you and see its hours before you go.
What happens after you pass
Once you pass the 35-question test, you receive your instruction permit (also called a learner's permit). This permit lets you practice driving with a licensed adult in the car. In Iowa, you must hold your instruction permit for at least 12 months before you can take the road test for your full license.
During those 12 months, you build up driving experience and practice the skills you will be tested on during the road test. The road test is different from the written test — it measures whether you can actually drive safely, not just whether you know the rules.
Frequently Asked Questions
Can I use my phone or notes during the test?
No. The test is proctored, meaning a staff member watches while you take it. You cannot use your phone, notes, or any other materials. You can only use the computer provided by the testing station to answer the questions.
What if I fail the test — how long do I have to wait to retake it?
In Iowa, there is no waiting period. You can retake the test the same day at most stations, though some locations may ask you to return another day. Each retake requires you to pay the testing fee again.
Are all 35 questions the same difficulty?
The questions vary in difficulty. Some are straightforward — for example, "What does a red octagon sign mean?" — while others require you to think through a scenario, like what to do if you hydroplane on wet pavement. The test is designed so that someone who has studied the manual can pass.
Can I take the test in a language other than English?
Iowa offers the written test in English and Spanish. Contact your local driver's license station to confirm that Spanish testing is available at your location, since not all stations may offer it.
Do I have a time limit to finish the 35 questions?
Iowa does not publish a strict time limit, but the test is designed to take 20 to 30 minutes. You have enough time to read each question carefully and think through your answer without rushing.
