You can usually fail about 6 to 8 questions and still pass, depending on your state
Most states let you miss between 6 and 8 questions on a 50-question permit test and still pass. That means you need a score of around 80% correct. However, the exact number varies by state — some allow you to miss as few as 5 questions, while others are slightly more lenient at 9 or 10. Your state's Department of Motor Vehicles (DMV) or equivalent agency sets the passing score, and it does not change based on how many times you take the test or what you scored before.
The passing score is the same whether you are taking your first permit test or retaking it after failing. There is no curve, no adjustment for difficulty, and no second chances built into a single test session. You either meet the threshold or you do not. If you fail, you can retake the test, but you will face the same standard the second time.
Key Takeaways
- Most states require an 80% passing score, which means you can miss 6 to 8 questions on a 50-question test.
- The exact number of questions you can miss varies by state, so check your state DMV's website for the precise passing score before you test.
- Passing scores do not change between attempts — you face the same standard on your first test and any retake.
- Some states use fewer than 50 questions or weight certain questions more heavily, so the number of allowable misses may not be exactly 6 to 8.
How passing scores work across different states
The passing score is set by law in your state, not by individual testing centers. Most states use an 80% threshold, but a few use 75% or 85%. On a 50-question test, 80% means 40 correct answers, so you can miss 10. On a 40-question test, 80% means 32 correct, so you can miss 8. The math changes with the test length, so you need to know both the number of questions and your state's passing percentage.
Some states also weight certain questions differently. For example, a question about right-of-way or impaired driving might count as two points instead of one. In those cases, the number of questions you can miss is not a straightforward calculation — you need to know the point value of each question you missed. Your state DMV website or the testing center should tell you how many points you earned and how many you needed to pass.
A few states use adaptive testing, where the difficulty of questions changes based on your answers. Even in those cases, the passing score remains fixed — you still need to reach a certain number of points to pass, regardless of which questions you saw.
What happens if you fail your permit test
If you score below the passing threshold, you fail the test. You will be told your score when ready or within a few minutes. Most states let you retake the test the same day or within a few days, though some require you to wait a week or longer before your next attempt. Each state sets its own waiting period, so check your DMV's rules before you schedule your first test.
You will pay the test fee again for each retake. That fee varies by state — it might be $10, $25, or more. There is usually no limit on how many times you can retake the test, but some states cap the number of attempts within a certain time period (for example, three attempts per month). If you keep failing, you may eventually need to wait longer between attempts or take a driver education course before trying again.
Your score on a failed test does not carry over or affect your score on the next attempt. Each test is separate. If you scored 75% on your first test and 78% on your second, you still failed both — the second score does not build on the first.
How to find your state's exact passing score
Your state DMV website lists the passing score in the permit test information section, usually under "Test Requirements" or "Scoring." Search for "[your state] DMV permit test passing score" or look for a link labeled "Permit Test Information" or "Knowledge Test." The page should tell you the total number of questions, the passing percentage, and how many correct answers you need.
If the website does not clearly state the passing score, call your local DMV office or visit in person. The staff can tell you the exact number of questions you can miss. You can also ask whether your state weights certain questions differently or uses any other scoring method that would change the calculation.
Do not rely on third-party test prep websites for the official passing score — they sometimes list outdated information or scores from other states. Always confirm with your state DMV directly before you test.
Common mistakes that cause people to fail
Most people who fail the permit test miss questions about right-of-way rules, speed limits in specific zones, and what to do at traffic signals or signs. These are the highest-stakes questions because they directly affect safety. Rushing through the test or not reading each question carefully is another common reason for failure — you might know the answer but select the wrong option because you misread the question.
Guessing on questions you are unsure about lowers your odds. If you do not know an answer, it is better to flag the question and come back to it if time allows, rather than guess and move on. Some testing centers let you review your answers before submitting, so use that time to reconsider any questions you were uncertain about.
Not studying the right material is also a major cause of failure. Your state DMV publishes a handbook or study guide that covers everything on the test. Using only a third-party app or website that does not match your state's rules can leave you unprepared for the actual test questions.
How to prepare so you do not miss too many questions
Start by reading your state's official driver handbook from beginning to end. It is free and covers every topic on the test. Take notes on sections about right-of-way, speed limits, parking, and what different road signs mean. These topics appear on almost every permit test and account for a large portion of the questions.
Use practice tests from your state DMV website or from reputable test prep sites that use your state's actual test questions. Take at least three full-length practice tests before your real test. If you score below 85% on a practice test, review the questions you missed and study that section of the handbook again before taking another practice test.
Study in short sessions over several days rather than cramming the night before. Your brain retains information better when you spread learning over time. Aim to study for 30 to 60 minutes per day for one to two weeks before your test date.
Frequently Asked Questions
Can I see which questions I missed after I fail?
Most states do not show you the specific questions you missed or your answer choices. You will see your overall score and sometimes the category of questions you struggled with (like "Road Signs" or "Right-of-Way"), but not the individual questions. This is by design — it prevents people from memorizing specific test questions and sharing them online. Ask the testing center what feedback they provide after a failed test.
Do I have to wait before retaking the test if I fail?
It depends on your state. Some states let you retake the test the same day or the next day. Others require a waiting period of one week or longer. Check your state DMV website or ask at the testing center when you schedule your first test so you know what to expect if you need to retake it.
What if I pass but barely — does that affect my permit?
No. A passing score is a passing score, whether you scored 80% or 95%. Your permit is valid either way, and your score does not appear on the permit itself or affect your driving record. The only thing that matters is whether you passed or failed.
Are the questions on the retake different from the first test?
Yes, the questions are different each time you take the test. The test bank contains hundreds of questions, and the testing computer selects a new random set for each attempt. However, the topics and difficulty level are the same, so studying the same material will prepare you for any version of the test.
What if I pass the permit test but fail the road test later?
Passing the permit test and passing the road test are separate requirements. Your permit test score does not affect your road test, and failing the road test does not invalidate your permit. You can retake the road test as many times as needed, and your permit remains valid during that time (as long as it has not expired).
