Most states let you miss 6 to 8 questions out of 50, depending on where you take the test
The number of questions you can miss and still pass varies by state. Most states require a score of 80 percent, which means you can miss up to 10 questions on a 50-question test. Some states are stricter — they require 85 percent, which allows only 7 or 8 misses on a 50-question exam. A few states use 70 percent as their passing score, which would let you miss 15 questions, but these are less common.
Your state's Department of Motor Vehicles (DMV) or equivalent agency sets the exact passing score and test length. The written permit test — also called the knowledge test — covers road signs, traffic laws, safe driving practices, and vehicle handling. You take it at a DMV office or an approved testing center, and you get your score when ready after you finish.
The safest approach is to check your state's DMV website before you test. Search for "permit test passing score" plus your state name, or call your local DMV office. They will tell you the exact number of questions on your test and the minimum score you need.

- You receive your score when ready after finishing the test at the DMV or testing center.
How passing scores work across different test lengths
Test length varies by state. Most states use a 50-question test, but some use 40, 45, or even 60 questions. The passing percentage stays the same — usually 80 percent — but the number of questions you can miss changes with the test size.
| Test Length | 80% Passing Score | Questions You Can Miss | 85% Passing Score | Questions You Can Miss |
|---|---|---|---|---|
| 40 questions | 32 correct | 8 | 34 correct | 6 |
| 45 questions | 36 correct | 9 | 38 correct | 7 |
| 50 questions | 40 correct | 10 | 42 correct | 8 |
| 60 questions | 48 correct | 12 | 51 correct | 9 |
If you are unsure whether your state uses 80 or 85 percent, aim to get at least 85 percent correct. That way you pass regardless of which standard your state uses. Most people who study the official handbook and take practice tests score well above the minimum.
Which states have stricter passing requirements
A handful of states require 85 percent instead of 80 percent. These include Georgia, Illinois, Louisiana, and Ohio, though this can change. A few others — like South Carolina — use different passing scores for different age groups. Younger drivers sometimes face a higher bar.
Some states also have separate tests for different license classes. A commercial driver's license (CDL) test, for example, may have a different passing score than a regular permit test. If you are testing for a CDL or a motorcycle endorsement, check your state's specific rules for that license type.
The best way to know your state's exact requirement is to visit your DMV's official website or call the office where you plan to test. Do not rely on what you heard from a friend — rules change, and your state may differ from neighboring states.
What happens if you fail the permit test
If you score below the passing threshold, you fail and must retake the test. Most states let you retake it the same day or within a few days, though some require you to wait 24 hours or a week between attempts. You usually pay a retest fee — typically $5 to $15 — each time you take it again.
There is no limit to how many times you can retake the test in most states, but some cap retakes at a certain number per year or require you to wait longer between attempts after multiple failures. Check your state's rules if you do not pass on your first try.
If you fail, review the questions you missed and study those topics more carefully before your next attempt. Many DMV websites show you which questions you got wrong, or you can ask the testing staff which areas gave you trouble.
How to prepare so you do not miss too many questions
The official driver's manual for your state is the primary source for test content. Every question on the permit test comes from material in that manual. Read it cover to cover, paying special attention to sections on speed limits, right-of-way rules, parking, and what different road signs mean.
Practice tests are the second key step. Taking multiple practice tests under timed conditions shows you which topics you need to review more. Practice tests also get you used to the format and pacing of the real test, so you are less likely to run out of time or panic during the actual exam.
Study for at least one to two weeks before your test date. Most people who spend that much time with the manual and practice tests score well above the passing threshold. If you are struggling with certain topics, focus your study time there rather than reviewing material you already know well.
What to expect on test day
You will sit at a computer terminal or paper test station at the DMV or testing center. The test is usually multiple choice, with four answer options per question. You have a set amount of time — typically 30 to 60 minutes depending on your state — to complete all questions.
You cannot go back and change answers on most computerized tests, so read each question carefully before you select your answer. If you are unsure about a question, make your best guess and move on. Leaving a question blank counts as wrong, so always choose an answer.
After you finish, the testing system scores your test when ready. You will see your score before you leave the testing center. If you passed, you get your permit that day or within a few days. If you failed, you can usually schedule a retest right then.
Frequently Asked Questions
Can I retake the permit test the same day if I fail?
Most states allow you to retake it the same day, but some require a 24-hour or one-week waiting period. Call your local DMV office to find out your state's rule. If you fail, ask the testing staff when you can schedule your next attempt.
What if I run out of time before finishing all the questions?
Any question you do not answer counts as wrong. If you are running out of time, make quick guesses on the remaining questions rather than leaving them blank. Aim to answer every question, even if you are not certain of the answer.
Do I need to score 80 percent on every section, or just overall?
Most states require only an overall passing score — you do not need to pass each section separately. However, a few states do have section minimums. Check your state's DMV website to see if there are any section-specific requirements.
Will the practice tests on the DMV website have the same passing score as the real test?
Yes, official DMV practice tests use the same passing score as the real test. If you consistently score above the passing threshold on official practice tests, you are ready for the real exam.
What topics do most people miss questions on?
Right-of-way rules, speed limits in different zones, and road sign meanings are the most commonly missed topics. Spend extra study time on these areas if you struggle with them on practice tests.
