Most states let you miss 6 to 8 questions out of 50, depending on where you live
The number of wrong answers you can have and still pass varies by state. Most states use a passing score of 80 percent, which means you need to answer 40 out of 50 questions correctly — leaving room for about 10 wrong answers. However, some states set the bar at 70 percent (35 correct out of 50), while others require 85 percent or higher. A few states use different test lengths entirely, with 30 or 40 questions instead of 50.
Your state's Department of Motor Vehicles (DMV) or equivalent agency sets this threshold, and it does not change between test dates. The passing score is the same whether you take the test on a Tuesday or a Saturday, and whether it is your first attempt or your fifth.
You will see your score when ready after you finish the test at most testing locations. The screen will tell you whether you passed or failed, and in many cases will show you which questions you missed so you can study those topics before your next attempt.
Key Takeaways
- Most states require an 80 percent passing score, which means you can miss about 10 questions on a 50-question test.
- Some states have lower thresholds (70 percent) or higher ones (85 percent or above), so check your state's specific requirement before test day.
- Your state's DMV website lists the exact passing score and the number of questions on the test.
- You will know your score before you leave the testing location, and many sites show you which questions you missed.
How passing scores work across different states
States fall into a few categories based on their passing threshold. The most common is 80 percent: you need 40 correct answers out of 50 questions. This is the standard in California, Texas, Florida, New York, and many others. A few states are stricter and require 85 percent (42 or 43 correct out of 50), including some that use this threshold to reduce the number of retakes. A smaller group allows 70 percent (35 correct out of 50), which is more forgiving but less common.
Some states also vary the test length. Colorado, for example, uses 40 questions instead of 50, so the math changes: 80 percent there means 32 correct answers. A handful of states use 30-question tests. The key is that your state's threshold is fixed — it does not get easier or harder based on how many people pass that day or how you performed on previous attempts.
You can find your state's exact passing score and test length on the DMV website. Search "[your state] DMV permit test passing score" or look under the "Written Test" or "Knowledge Test" section of the site. Write down both numbers before you study, because knowing exactly how many you can miss helps you focus your preparation.
What happens if you fail and need to retake the test
If you score below the passing threshold, you fail that attempt. Most states let you retake the test the same day or within a few days, though a few require you to wait a week or longer between attempts. There is usually a fee for each retake — typically $10 to $25 — and you will need to schedule another appointment or show up during walk-in hours.
When you retake the test, the passing score does not change. You still need the same percentage correct as you did on your first attempt. The questions may be different (most states randomize the order or pull from a larger question bank), but the threshold stays the same.
Many testing sites show you which questions you missed after a failed attempt, either on screen or on a printed report. Use that information to study the weak areas before your next try. If you missed several questions about right-of-way rules, for example, spend extra time on that chapter in your state's driver's manual.
How to find your state's specific passing requirement
Go to your state's DMV or Department of Driver Services website and search for "written test" or "knowledge test." Look for a page titled something like "Permit Test Information" or "Written Exam Requirements." This page will list the number of questions, the passing score as a percentage, and sometimes the number of correct answers you need.
If the website does not clearly state the passing score, call your local DMV office or the state DMV phone line. They can tell you the exact threshold in under a minute. Write it down so you know your target before you start studying.
Some states also publish sample tests or practice questions on the DMV website. These are worth taking because they show you the question format and difficulty level. A practice test score that is close to your state's passing threshold tells you whether you are ready for the real test or need more study time.
Why the passing score matters for your study plan
Knowing how many you can miss changes how you approach studying. If your state requires 80 percent and you are scoring 75 percent on practice tests, you are close but not there yet — you need to focus on the topics where you are weakest. If you are scoring 90 percent on practice tests, you have a comfortable cushion and can test soon.
The passing score also tells you which questions matter most. On an 80 percent threshold, you can afford to miss a few questions even if you are not 100 percent sure about them. On an 85 percent threshold, you have less room for error and should study until you feel confident on nearly every topic.
Use practice tests that match your state's test format and length. If your state uses 50 questions, practice with 50-question tests. If it uses 40, find 40-question practice tests. This trains your brain for the actual test conditions and gives you an accurate sense of whether you will pass.
Common topics where people lose points
Right-of-way rules, speed limits in different zones, and parking regulations are the most common sources of missed questions across most states. These topics have many specific rules and exceptions, so they require careful study. Road signs and their meanings are also frequently missed, especially the less common ones like "Do Not Enter" versus "Wrong Way."
Impaired driving laws and seat belt requirements trip up many test-takers because the rules vary slightly by state and by age. Pedestrian and bicycle rules are another weak spot — many people do not study these thoroughly because they assume they are obvious, but the test often includes specific scenarios.
If you take a practice test and miss several questions in one category, go back to your state's driver's manual and read that section twice. Then take another practice test focused on that topic. Repeating this cycle for your weak areas is more effective than re-reading the entire manual.
Frequently Asked Questions
Can I pass if I get exactly the passing score, or do I need to score higher?
You pass if you meet or exceed the passing score. If your state requires 80 percent and you get exactly 80 percent, you pass. You do not need to score higher. However, scoring higher gives you a safety margin if you misread a question or second-guess yourself.
Do different DMV locations in my state have different passing scores?
No. The passing score is set by your state, not by individual DMV offices. Every location in your state uses the same threshold. The test questions may vary slightly between locations, but the passing percentage is identical.
What if I pass but barely — does that affect my license?
No. A pass is a pass. Whether you score 80 percent or 95 percent, you get the same permit. Your score does not appear on your license or affect your driving record. It only determines whether you move forward to the road test.
Are practice tests harder or easier than the real permit test?
It depends on the source. Official DMV practice tests are usually the same difficulty as the real test. Third-party apps and websites vary — some are easier, some are harder. Use your state's official practice test first to get an accurate baseline, then supplement with other sources if you need more material.
If I fail, do I have to retake the entire test or just the questions I missed?
You retake the entire test. There is no partial retake option. You will answer all the questions again, though they may be in a different order or pulled from a different section of the question bank.
