You can retake the test, but the rules change once you turn 18

At 18, you are no longer a minor, which means your state's learner's permit rules shift. Most states still let you retake the written test and the driving test as many times as you need, but the waiting periods between attempts may be different, and you may lose some of the supervised-driving protections that applied when you were under 18. Some states also charge a new fee for each retake, while others do not. The exact rules depend on your state's Department of Motor Vehicles (DMV) or equivalent agency.

The most important thing to know is that turning 18 does not automatically cancel your permit or make it harder to get one — it just means you are now treated as an adult applicant rather than a minor applicant. You still have the right to retake the test, and you still have time to get your license before you need to renew your permit.

Key Takeaways

  • You can retake your learner's permit test at 18, but check your state's DMV website to see if the waiting period or fee has changed now that you are an adult.
  • Some states charge a new process fee for each retake; others do not, so confirm the cost before you go to the DMV.
  • Your permit has an expiration date — usually two to eight years depending on your state — so check when yours expires and plan your retake before that date.
  • If you failed the written test, you can usually retake it within days or weeks; if you failed the driving test, the wait is often longer and may require a new appointment.

How the rules change at 18

When you were under 18, your state likely had a graduated licensing system that gave you a learner's permit first, then a restricted license, then a full license. Now that you are 18, most states let you skip some of those steps or move through them faster. However, this also means you lose some protections — for example, many states no longer require a supervising adult in the car with you once you turn 18, even if you still have only a learner's permit.

The waiting period between your failed test and your next attempt may also change. Some states have a shorter waiting period for adults (sometimes just a few days), while others keep the same waiting period regardless of age. A few states let you retake the written test when ready on the same day if you fail, but this is less common. Check your state's DMV website or call the local DMV office to find out the exact waiting period for your age and situation.

Your permit itself does not expire just because you turned 18, but it will expire on whatever date was printed on it when you first got it. If your permit expires before you pass your driving test and get your license, you will need to renew it — which usually means paying another fee and possibly retaking the written test.

What you need to retake the test

To retake your learner's permit test, bring the same documents you brought the first time: a valid photo ID (passport, state ID, or birth certificate with a photo ID), proof of your Social Security number, and proof of your current address. Some states also require proof that you completed a driver's education course, even if you already did one before your first attempt — check your state's requirements before you go.

You will also need to pay the retake fee. At 18, some states charge the same fee as they did when you were under 18, while others charge a new full process fee. A few states do not charge for retakes at all. Call your local DMV or check the website to find out what you owe before you arrive, so you bring the right amount of cash or know which payment methods they accept.

If you are retaking the driving test (not just the written test), you will also need to bring a vehicle that is registered, insured, and passes a safety inspection. The car must have working brakes, lights, wipers, and mirrors. Some states require the vehicle to be inspected by the DMV before the test; others just require you to certify that it is safe. Ask the DMV when you schedule your test.

Retaking the written test

The written test covers traffic laws, road signs, and safe driving practices specific to your state. It is usually multiple choice and taken on a computer at the DMV, though some states still use paper tests. You typically need to score 70 to 80 percent to pass, depending on your state. If you failed the first time, the test will be the same format and cover the same material, so studying the same study guide will help.

Most states let you retake the written test within a few days of failing, though some require a waiting period of one to two weeks. You can usually schedule your retake online through your state's DMV website, by phone, or by walking in to a local office. Walk-ins are often faster if you are willing to wait, but some DMV offices now require appointments only. Check your state's website to see which method is available in your area.

If you fail the written test a second time, do not panic — most states let you retake it as many times as you need. However, each retake may cost money, and you may hit a point where the DMV requires you to take a driver's education course or retake a behind-the-wheel lesson before trying again. This is less common at 18 than it was when you were younger, but it varies by state.

Retaking the driving test

The driving test is usually longer to schedule than the written test, and the waiting period between attempts is often longer too. Most states require you to wait at least one to two weeks between driving test attempts, though some allow you to retake it sooner if you cancel and reschedule. You will need to bring the same vehicle, the same documents, and proof that you have a valid learner's permit (or a valid license if you are retesting after getting your permit).

The test itself usually lasts 20 to 40 minutes and covers basic driving skills: starting the car, following traffic laws, parking, turning, and responding to road hazards. The examiner will be in the car with you and will give you directions. If you failed because of a specific mistake — like hitting a curb during parking or not checking your mirror — focus your practice on that skill before your next attempt.

At 18, you may have more flexibility in scheduling. Some states let adults book their driving test online or by phone weeks in advance, while others still require you to go in person to schedule. A few states have a backlog and may not have an opening for several weeks or months, especially in busy urban areas. Call ahead or check online to see how long the wait is in your area.

What happens if your permit expires before you pass

Your learner's permit has an expiration date printed on it — usually two to eight years from the date you received it, depending on your state. If that date passes before you pass your driving test and get your license, you will need to renew your permit. Renewing usually means paying a fee (often the same as the original process fee) and retaking the written test, though some states waive the written test if you renew within a certain time frame.

To avoid this, check the expiration date on your permit now and count backward. If your permit expires in less than a year, prioritize scheduling your driving test soon. If it expires in more than a year, you have time to study and retake the written test if you need to, then practice for the driving test. If you are running out of time, some states let you renew your permit early — check your state's DMV website to see if this is an option.

Moving forward if you are stuck

If you have failed the written test multiple times, consider taking a driver's education course or working with a professional driving instructor. At 18, you are not required to take a course the way you might have been under 18, but many people find that classroom instruction or one-on-one lessons help them understand the material better. Some driving schools also offer test-prep classes that focus specifically on the written test or the driving test in your state.

If you have failed the driving test multiple times, a professional instructor can identify specific skills you need to work on — like parallel parking, merging, or staying calm under pressure. A few lessons (usually three to five) can make a real difference, and many people pass on their next attempt after working with an instructor. The cost varies, but most instructors charge $50 to $150 per hour.

If cost is a barrier, some community colleges and nonprofits offer low-cost or free driver's education programs. Check with your local library, community center, or school district to see what is available in your area.

Frequently Asked Questions

Do I have to retake the written test if I only failed the driving test?

No. If you passed the written test the first time, you do not have to retake it. Your learner's permit is still valid, and you can use it to practice and retake the driving test whenever you are ready. Just make sure your permit has not expired.

Can I get a license without a learner's permit if I am 18?

This depends on your state. Some states let 18-year-olds skip the learner's permit stage and go straight to the driving test, while others require everyone to get a permit first. Check your state's DMV website or call to find out which applies to you. If your state does allow this, you would still need to pass the written test.

What if I move to a different state after failing my test?

Your learner's permit is only valid in the state that issued it. If you move, you will need to get a new permit from your new state, which usually means retaking the written test and paying a new fee. However, some states have reciprocal agreements and may waive the written test if you already passed it in another state — call your new state's DMV to ask.

How many times can I retake the test before the DMV stops letting me?

Most states do not have a limit on how many times you can retake the written test. For the driving test, some states have a limit (often three to five attempts per permit), after which you have to renew your permit and start over. Check your state's rules to see if there is a limit and what happens if you hit it.

Will failing my test affect my insurance or driving record?

No. A failed test does not go on your driving record or affect your insurance rates. Your driving record only includes tickets, accidents, and violations that happen after you have a license. Until then, the test results are just between you and the DMV.
