The number of questions varies by state, and most states don't require a written test at all for renewal
If you're renewing your driver's license, you may not face a written test at all. Most states allow you to renew by mail, online, or at the DMV without taking any test — you straightforward verify that your information is current and pay the renewal fee. The written knowledge test is typically required only when you're getting your first license or when a state has specific reasons to require retesting, such as after a suspension or if you're upgrading to a commercial license.
When a written test is required during renewal, the number of questions depends entirely on your state's rules. Some states use 20 questions, others use 30 or more. A few states have moved to computerized testing that may include different question counts. The best way to know what you'll face is to check your state's DMV website directly, since the rules differ significantly from one state to another.

- Written tests during renewal are most common after a license suspension, when renewing a commercial license, or in states that periodically retest all drivers.
- If you do face a test, it covers the same road rules and safety topics as the original licensing test, and most states provide a study guide online.
Which states require a written test at renewal
A handful of states require all drivers to retake a written test when renewing, though this is uncommon. Most of these states space out the requirement — for example, requiring the test only every other renewal cycle or only for drivers over a certain age. Other states require a test only in specific situations: after a traffic violation, following a suspension, or when renewing a commercial driver's license.
Your state's DMV website will clearly state whether a written test is part of your renewal process. If you're unsure, you can call your local DMV office or check the renewal notice you received in the mail — it typically tells you what to expect and what documents to bring. Some states also send renewal reminders online that specify whether a test is required for your particular renewal.
Question counts and test formats by state
States that do require renewal tests typically use between 20 and 40 questions. A common format is 20 multiple-choice questions covering traffic laws, road signs, and safe driving practices. Some states have moved to computer-based testing that may shuffle questions or use different formats, such as showing a road sign image and asking you to identify it.
A few states use shorter tests — 15 to 20 questions — while others use longer ones with 30 to 40 questions. The passing score is usually 70 to 80 percent, meaning you typically need to answer 14 to 16 questions correctly on a 20-question test. Your state's DMV website or renewal materials will specify both the number of questions and the passing score you need.
What the renewal test covers
If your state requires a written test during renewal, it covers the same material as the original driver's license test: traffic laws, right-of-way rules, speed limits, parking regulations, and the meaning of road signs and signals. The test may also include questions about impaired driving, distracted driving, and seat belt laws. Some states include questions specific to their state's unique traffic laws or road conditions.
The test does not cover driving skills — that is, you won't be asked to demonstrate parallel parking or perform a road test. It is purely a written or computer-based knowledge test. Most states provide a free study guide or handbook on their DMV website that covers all the topics the test will include, so you can review before you take it.
How to prepare if you need to take the test
Start by downloading your state's driver's manual or study guide from the DMV website. These guides are free and cover every topic the test will include. Read through the sections on traffic laws, road signs, and safe driving practices. Many states also offer practice tests online — some on the official DMV site, others through third-party sites — that let you see the types of questions you'll face.
If you haven't driven much since you got your original license, or if you're renewing after a long time, spend extra time on road signs and right-of-way rules. These are the most common areas where people miss questions. Take the practice test more than once so you become familiar with the question format and can identify weak areas. Most people who use the official study guide and take a practice test pass on their first attempt.
What happens if you fail the test
If you fail the written test, you typically get a second chance to retake it the same day or within a short window — usually within a few days or weeks, depending on your state. You may have to pay a retest fee, which varies by state but is usually between $5 and $20. Some states allow you to retake the test when ready after failing; others require you to wait a day or two before your next attempt.
Your license renewal will be delayed until you pass the test. If your current license is about to expire, check your state's rules on whether you can continue driving on an expired license while your renewal is pending. Some states allow a grace period; others do not. Contact your DMV to understand the rules in your state if you're concerned about timing.
Renewal by mail or online versus in-person testing
If your state allows mail-in or online renewal and you don't have a reason to retake a test, that is almost always the faster and easier route. You won't need to visit the DMV, and you won't face any written test. Mail-in renewal typically takes two to four weeks; online renewal is often faster, sometimes producing a temporary license you can print when ready.
In-person renewal at the DMV is required only if your state mandates it, if you need to update your photo, or if you're renewing after a suspension or other issue. If an in-person visit is required and a test is part of the process, the DMV will tell you this when you schedule your appointment or when you receive your renewal notice. Bring the study materials with you if you're concerned — you can review them in the waiting area before you take the test.
