The passing score is usually 80 percent, but it varies by state

Most states require you to answer at least 80 percent of the questions correctly to pass your written permit test. That means if your test has 50 questions, you need to get 40 right. However, some states set the bar at 70 percent, and a few require 85 percent. Your state's Department of Motor Vehicles (DMV) or equivalent agency sets this threshold, so the exact number depends on where you are taking the test.

The passing score is separate from how many questions are on the test itself. A state might have 40 questions with an 80 percent passing score, or 50 questions with a 70 percent passing score — the math works out differently, but the difficulty level is meant to be similar. When you register for your test, your state's DMV website will tell you both the number of questions and the passing score you need.

Key Takeaways

  • Most states require 80 percent correct answers to pass, though some use 70 percent or 85 percent.
  • You can find your state's exact passing score and number of test questions on your DMV website before you take the test.
  • If you score below the passing threshold, you can usually retake the test after a waiting period, which ranges from the same day to several days depending on your state.
  • The passing score is the same for everyone taking the test in that state — there is no curve or adjustment based on how many people pass.

How states decide what the passing score should be

States choose their passing score based on what they believe demonstrates safe driving knowledge. The logic is that someone who knows 80 percent of the material knows enough to drive safely, while someone who knows only 70 percent might miss critical safety rules. Different states have different philosophies about this threshold, which is why you see variation across the country.

The test questions themselves are also designed with the passing score in mind. If a state uses 80 percent, the questions are written to be moderately difficult — not so straightforward that almost everyone passes, and not so hard that most people fail. The goal is to create a test where someone who studied the driver's manual thoroughly can pass, but someone who guessed or skimmed cannot.

What happens if you score below the passing threshold

If you do not reach the passing score, you will not get your permit. You will be told your score when ready after the test, usually on the computer screen or on a printed receipt. Your state's DMV will tell you how long you must wait before you can retake the test — this waiting period is typically between one day and one week, depending on your state.

You can take the test as many times as you need to pass. Each attempt costs the test fee again, which ranges from about $10 to $50 depending on your state. Most people pass on the second or third attempt after studying the material they missed. There is no limit to how many times you can retake it, though some states may require you to wait longer between attempts if you fail multiple times in a row.

How to find out your state's specific passing score

Go to your state's DMV website and search for "written permit test" or "knowledge test." The page will list the number of questions, the passing score, and often sample questions you can practice with. Many states also provide a free study guide or link to one. This is the most reliable place to find the exact number because it comes directly from the agency that administers the test.

If you cannot find it on the website, call your local DMV office. They can tell you the passing score in seconds and may also tell you whether the test is currently being offered at your location, since some offices have limited hours or require appointments.

Why the passing score matters for your studying

Knowing the passing score helps you set a realistic study goal. If your state requires 80 percent, you should aim to score higher than that when you practice — shooting for 90 percent gives you a safety margin for test-day nerves or questions you are unsure about. If you are consistently scoring 85 percent on practice tests, you are likely ready to take the real test.

The passing score also tells you how much of the driver's manual you truly need to know. You do not have to memorize every detail, but you do need to understand the core safety rules, road signs, and right-of-way situations that make up the bulk of the test. Focusing your study on these high-value topics is more efficient than trying to memorize every possible question.

Frequently Asked Questions

Can I see which questions I got wrong after I fail?

Most states show you your score but not the specific questions you missed. Some states provide a breakdown by topic (for example, "You scored 70 percent on road signs and 85 percent on right-of-way"), which helps you know what to study before your next attempt. Ask the test administrator or check your state's DMV website to see what feedback you will receive.

Is the passing score the same at every DMV office in my state?

Yes. The passing score is set by your state, not by individual offices. Every person taking the permit test in your state must reach the same score to pass, whether they test in a city office or a rural one.

Do I need to pass with a higher score to get a commercial permit?

Commercial driver's license (CDL) tests usually have a higher passing score than regular permit tests — often 80 percent for the general knowledge test and 80 percent for the air brakes test if your vehicle has them. Check your state's DMV website for CDL-specific requirements if that is what you are pursuing.

What if I pass the test but fail the road test later?

Your written permit score does not expire. Once you pass the written test, you have your permit and can practice driving. If you fail the road test, you can retake it without retaking the written test. The waiting period and retake rules for the road test are separate from the written test rules.
