The written permit test for drivers 18 and older has 46 questions

If you are 18 or older and taking your written permit test, you will answer 46 questions. The test covers traffic laws, road signs, safe driving practices, and what to do in emergency situations. You need to answer at least 39 questions correctly to pass — that is about 85 percent.

The number of questions stays the same across all states, though the specific content and passing score can vary slightly depending on where you live. Some states set the passing score at 80 percent instead of 85 percent, which means you might need 37 correct answers rather than 39. Check your state's Department of Motor Vehicles website to confirm the exact passing score in your state.

Key Takeaways

  • The written permit test for adults 18 and older contains 46 questions total.
  • You must answer at least 39 questions correctly to pass in most states, though some states require 37 correct answers (80 percent).
  • Questions cover road signs, traffic laws, safe driving, and emergency procedures.
  • The test is the same whether you are 18, 25, or 65 — the age-based difference is only in the written test length for younger drivers.
  • You can retake the test if you do not pass, usually the same day or within a few days.

What the test covers

The 46 questions are drawn from your state's driver's manual and test your understanding of real driving situations. You will see questions about speed limits, right-of-way rules, parking, following distance, and how to handle weather or mechanical problems. Road sign recognition makes up a significant portion — you need to know what each sign means and when to follow its instruction.

Questions are multiple choice with four answer options. Some ask what you should do in a specific situation (for example, "You see a red octagon sign ahead. What should you do?"). Others ask you to identify a sign from a description or to recall a specific traffic law. The test does not include trick questions, but it does test whether you understand the reason behind the rule, not just the rule itself.

How the test is administered

You take the written test at your local Department of Motor Vehicles office or an authorized testing location. Most states now offer computer-based testing, where you sit at a terminal and answer questions on screen. Some locations still use paper tests, though these are becoming less common. The test usually takes 30 to 45 minutes to complete.

You will be asked to show a valid ID before you start. Bring any documents your state requires — usually a proof of residency, your Social Security number, and any paperwork you filled out when you scheduled the test. You cannot bring notes, phones, or other study materials into the testing room.

Passing and retaking the test

If you pass, you will receive your permit when ready or within a few days, depending on your state. If you do not pass, you can usually retake the test the same day or within a short window — often three to seven days. There is usually a fee for each attempt, so studying before you test saves money.

When you retake the test, you will get a different set of 46 questions from the same pool of material. The passing score remains the same. Most people pass on their second or third attempt if they study the driver's manual between tests and focus on the areas where they struggled the first time.

How this differs from the under-18 permit test

Drivers under 18 take a different written test with more questions — usually 50 questions instead of 46. The under-18 test also has a higher passing score in many states (often 90 percent instead of 85 percent). The content is similar, but the under-18 test may include more questions about graduated licensing restrictions and parental consent rules.

Once you turn 18, you do not have to retake the test. Your permit remains valid. The difference in test length is only for the initial written test you take when you first explore for a permit.

Preparing for the 46-question test

The best way to prepare is to read your state's driver's manual from start to finish. Most states publish this online for free on the DMV website. As you read, take notes on rules that surprise you or that you find confusing. Many people find it helpful to read the manual twice — once all the way through, and a second time focusing on sections where they felt less confident.

After reading the manual, use practice tests to see which topics need more study. Practice tests show you the format and style of the real test and help you get comfortable with the computer interface if your state uses computer-based testing. Take practice tests under timed conditions — give yourself the same 45 minutes you will have on test day.

What happens if you do not pass

Not passing does not affect your driving record or your ability to get a permit later. It straightforward means you need to study more and retake the test. There is no penalty beyond the retesting fee. Most states allow you to retake the test within days, so you can study the material you missed and try again quickly.

If you fail multiple times, ask the testing staff or your DMV office which sections of the manual are giving you the most trouble. Some DMVs offer study guides or videos focused on the hardest topics. You can also ask a friend or family member to quiz you on the material using the practice test questions.

Frequently Asked Questions

Can I use a calculator or notes during the test?

No. You cannot bring any materials into the testing room except your ID and required documents. The test does not require math — all questions are about traffic laws and road signs. You must answer from memory.

How long is the permit valid after I pass?

Permit validity varies by state, but most permits are valid for four to eight years. Check your state's DMV website for the exact length. Your permit will show the expiration date on the card itself.

Do I have to pass the written test before I take the driving test?

Yes. You must pass the written permit test first and hold a valid permit for a set period (usually at least 30 days) before you can schedule the driving test. Some states require you to hold the permit for longer, especially if you are under 18.

What if I fail the test by just one or two questions?

You still do not pass. The passing score is set — usually 39 out of 46 correct answers. There is no partial credit or rounding up. If you miss the passing score by one question, you will need to retake the test. Most people who fail by a small margin pass on their next attempt after reviewing the material they missed.

Is the test the same in every state?

No. Each state writes its own test based on that state's traffic laws and road signs. The format and number of questions (46 for adults 18 and older) are the same, but the specific questions and content reflect your state's rules. You must study your state's driver's manual, not another state's.
