Most states require 80 percent to pass the written permit test

The passing score for a driver's permit test is most commonly 80 percent, meaning you need to answer at least 8 out of every 10 questions correctly. However, this varies by state. Some states set the bar at 70 percent, while others require 85 percent or higher. A few states use a different system altogether — they allow a certain number of wrong answers rather than a percentage.

The test itself is usually 30 to 50 questions long, depending on your state. That means on an 80 percent passing score, you might be allowed to miss 6 questions on a 30-question test, or 10 questions on a 50-question test. Your state's Department of Motor Vehicles (DMV) or equivalent agency publishes the exact passing score and test length before you sit for the exam.

Key Takeaways

  • The most common passing score is 80 percent, but your state may require 70, 75, 85, or another threshold — check your state DMV website to find the exact number.
  • Test length varies from 30 to 50 questions depending on your state, so the number of questions you can miss changes even if the percentage stays the same.
  • Some states count wrong answers instead of percentages, so you might see "you can miss no more than 6 questions" rather than a percentage.
  • The passing score applies only to the written test; the road test (driving portion) is usually scored differently and has its own passing standard.

How passing scores differ by state

Each state sets its own passing score, and there is no single federal standard. The variation reflects different decisions about how much knowledge a new driver needs to demonstrate. A state that requires 85 percent is making a stricter judgment than one requiring 70 percent, though both are legal and both produce licensed drivers.

To find your state's exact passing score, visit your state DMV website and search for "permit test passing score" or "knowledge test requirements." The information is usually in the section about the written exam or in the permit test study guide. Some states post it clearly on the main page; others bury it in a PDF. Calling your local DMV office is faster if you cannot find it online.

What happens if you score below the passing percentage

If you score below your state's passing percentage, you do not pass the test. You will be told your score when ready or within a few days, depending on whether your test was computer-based or paper. Most states allow you to retake the test, but there is usually a waiting period — commonly 24 hours to 7 days — before you can try again.

Each retake may cost a fee, typically $5 to $15, though some states allow one or two free retakes within a certain window. You will study the same material and take a similar test, but the specific questions are usually different. There is no limit to how many times you can retake the test in most states, though a few cap it at a certain number per year.

The difference between the written test and the road test

The written permit test and the road test (also called the driving test or practical test) are scored separately, and they have different passing standards. The written test is scored as a percentage, as described above. The road test is usually scored on a points system or a pass/fail basis, where an examiner watches you drive and marks errors.

On the road test, you typically lose points for things like failing to signal, hitting a curb, or not checking mirrors. The number of points you can lose and still pass varies by state — some allow 15 points of deductions, others allow 20 or 30. You must pass both tests to get your license. Passing the written test does not may provide you will pass the road test, and vice versa.

How to prepare for the written test

Your state DMV provides a study guide or handbook that covers everything on the written test. This guide is free and is usually available online as a PDF or in print at your local DMV office. The questions on the actual test come directly from the material in this guide, so studying it is the most direct way to prepare.

Many states also offer practice tests online, either on the DMV website itself or through third-party sites. These practice tests use real questions from past exams or questions written in the same style. Taking practice tests helps you get used to the format and identify which topics you need to study more. Aim to score at or above the passing percentage on practice tests before you take the real exam.

What the permit test actually covers

The written permit test focuses on traffic laws, road signs, and safe driving practices specific to your state. You will be asked about speed limits, right-of-way rules, what different signs mean, how to handle emergencies, and what to do in bad weather. The test does not cover how to physically operate a car — that is what the road test checks.

Most questions are multiple choice with four options. Some states include true/false questions or ask you to identify a sign from an image. The test is designed to measure whether you know the rules well enough to drive safely on public roads. Memorizing the study guide is usually enough to pass; you do not need to have driven a car before taking the test.

Frequently Asked Questions

Can I retake the permit test the same day I fail?

Most states require you to wait at least 24 hours before retaking the test, though some allow you to retake it the same day. A few states have longer waiting periods of 3 to 7 days. Check your state DMV website or call ahead to confirm the waiting period, as it affects when you can schedule your next attempt.

Do I need to score 80 percent on every section of the test, or just overall?

Almost all states require you to score at the passing percentage overall — meaning your total score across all questions. A few states also require a minimum score on specific sections, such as road signs or right-of-way rules. Your state study guide will note if there are section-specific requirements.

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

You keep your permit and can retake the road test. Your written test score does not expire just because you failed the driving portion. However, permits themselves do expire — usually after 6 months to 2 years depending on your state — so you will need to renew your permit if too much time passes before you pass the road test.

Is the passing score the same for a regular license and a commercial license?

No. Commercial driver's license (CDL) tests have different passing scores and cover different material. A CDL written test is usually longer and may require a higher percentage to pass. If you are preparing for a CDL, check your state DMV's CDL-specific study guide and requirements.
