The written test has 40 questions in most states

Most states give you a written test of 40 questions when you take your driver's license exam. You'll typically need to answer 30 or 32 correctly to pass — that's usually 75 to 80 percent. The exact number of questions and the passing score vary by state, so check your state's DMV website before you test.

The test covers traffic laws, road signs, right-of-way rules, and safe driving practices. Questions are multiple choice, with three or four answer options. You answer them on a computer at the DMV office, or on paper if your state still uses that format. Most states let you take the test in multiple languages.

You'll also take a separate road test — the driving portion where an examiner sits in the car with you. That's not a written test and doesn't have a set number of questions. Instead, the examiner watches how you handle the vehicle, follow instructions, and respond to traffic.

Key Takeaways

  • Most states use a 40-question written test, and you need to score 75 to 80 percent to pass.
  • The written test covers traffic laws, road signs, and safe driving rules in multiple-choice format.
  • Some states have fewer questions — check your state DMV website for the exact number before you test.
  • The road test (driving portion) is separate from the written test and doesn't have a fixed question count.
  • You can usually take the written test in languages other than English at your DMV office.

How the test is organized by topic

The 40 questions are divided into categories that reflect what you need to know to drive safely. Typically, you'll see questions on traffic signs and their meanings, right-of-way rules at intersections, speed limits and when they change, parking rules, and what to do in bad weather or emergencies.

Other common topics include following distance, how to handle a skid or blowout, the effects of alcohol and drugs on driving, and seat belt and child safety seat laws. Some states weight certain topics more heavily — for example, you might see more questions about right-of-way than about parking, because right-of-way mistakes cause more crashes.

The questions pull from your state's driver's manual, which is free and available online or in print at the DMV. Reading the manual before you test is the most direct way to prepare, since the test questions come straight from it.

Variations by state

Not every state uses 40 questions. Some states use 35, others use 50. A few states have different test lengths for different license classes — for example, a commercial driver's license (CDL) test is longer and more detailed than a regular passenger vehicle test.

Some states also offer a knowledge test waiver if you've completed an approved driver education course. In those cases, you skip the written test and go straight to the road test. Rules about this vary widely, so ask your DMV whether your state offers it.

A handful of states still allow you to take the test on paper instead of a computer, though most have moved to computer-based testing. The content is the same either way.

What happens if you fail

If you don't reach the passing score, you can retake the test. Most states let you retake it the same day or within a few days, though some require you to wait a week. Each state sets its own rules, and some charge a fee each time you retake the test.

When you retake it, you'll get a different set of 40 questions from the same pool. The topics stay the same, but the specific questions change. That's why studying the manual matters more than memorizing one particular test — you need to understand the material, not just memorize answers.

If you fail multiple times, some states require you to take a driver education course or meet with a DMV representative before you can test again. Check your state's rules after your first attempt so you know what to expect.

How to prepare for the written test

Start by reading your state's driver's manual from beginning to end. It's written in plain language and covers everything the test will ask about. Most manuals are 40 to 60 pages and take a few hours to read. You can read it from your state DMV website or pick up a printed copy at any DMV office.

After you've read the manual, use practice tests. Most state DMV websites offer free practice tests online that mirror the real test — same number of questions, same format, same topics. Taking a practice test tells you which areas you need to study more. If you score below 80 percent on a practice test, go back to the manual and review those topics.

Some people use study apps or third-party websites, which can help, but stick with materials based on your state's official manual. Questions and rules vary by state, so a practice test from another state might teach you the wrong answer for your state's test.

The road test is separate and has no fixed question count

After you pass the written test, you'll schedule a road test. An examiner sits in the car with you and watches you drive. They don't ask 40 questions — instead, they give you instructions ("Turn left at the next light," "Parallel park here") and watch how you handle the vehicle and follow traffic laws.

The road test usually lasts 15 to 30 minutes. You'll demonstrate basic skills like starting the car, steering, braking, turning, and parking. The examiner is looking for safe habits: checking mirrors, signaling before turns, maintaining safe speed, and responding correctly to traffic signs and signals.

You pass or fail the road test based on your overall performance, not on a point system. If you fail, you can retake it after a waiting period — usually a few days to a week, depending on your state.

Frequently Asked Questions

Can I use my phone or notes during the written test?

No. The DMV doesn't allow phones, notes, or any outside materials during the test. You'll be in a controlled testing area, and the examiner will collect any personal items before you start. Attempting to use outside materials can result in an automatic fail and may affect your ability to retake the test.

What if I don't speak English well?

Most states offer the written test in multiple languages, including Spanish, Chinese, Vietnamese, and others. Contact your DMV office to find out which languages are available in your area. You may need to request a translated test when you schedule your appointment, or it may be available on the day of your test.

Do I need to memorize the entire driver's manual?

No, but you should understand the main concepts. Focus on traffic laws, road signs, right-of-way rules, and safe driving practices. The practice tests will show you which topics appear most often. If you understand the reasoning behind the rules, you'll answer questions correctly even if you haven't seen that exact question before.

How long do I have to answer all 40 questions?

Most states give you 30 to 60 minutes to complete the test, which is plenty of time. You can spend as long as you need on each question. If you're unsure about an answer, you can skip it and come back to it before you submit the test.

What's the difference between a learner's permit test and a driver's license test?

Both are written tests with the same number of questions and similar content. The learner's permit test is usually slightly easier and covers the basics of safe driving. The driver's license test goes deeper into traffic laws and hazard awareness. Some states use the same test for both; others have different versions.
