What you need to know about driver's licenses for adults
Once you turn 18, you can get a standard driver's license in most states without parental permission or supervision. The process is largely the same whether you're getting your first license or renewing an expired one — you'll visit your state's Department of Motor Vehicles (or equivalent agency), pass a written test and driving test, and provide proof of identity and residency. The main difference from getting a license as a minor is that you no longer need a parent or guardian to sign off, and you may have different restrictions removed (like nighttime driving limits or passenger limits, depending on your state).
Each state sets its own rules about testing, fees, and document requirements, so the exact process varies. However, the basic steps and documents you'll need are consistent across most states.
Key Takeaways
- You can get a driver's license at 18 without parental consent, but you must pass both a written knowledge test and a driving test at your state's DMV.
- You will need to bring proof of identity (such as a birth certificate or passport), proof of residency (such as a utility bill or lease), and your Social Security number or ITIN.
- Fees for a new license or renewal vary by state but typically range from $20 to $100, and licenses are usually valid for four to eight years depending on your state.
- If you already have a learner's permit or junior license, you may skip the written test and go straight to the driving test, though rules vary by state.
Documents you'll need to bring
Before you go to the DMV, gather the following documents. Bring originals or certified copies — photocopies are usually not accepted. If you don't have one of these documents, the DMV can tell you what alternatives they accept.
Proof of identity: A birth certificate, U.S. passport, passport card, or state ID card. Some states also accept a Consular Report of Birth Abroad or a Certificate of Naturalization.
Proof of residency: A utility bill, lease agreement, mortgage statement, bank statement, or government mail addressed to you at your current address. The document must be recent (usually within the last 60 days) and show your full name and address. A piece of mail from a school or employer may work in some states.
Social Security number or ITIN: Bring your Social Security card or a document showing your number. If you don't have a Social Security number, you'll need an Individual Taxpayer Identification Number (ITIN) from the IRS.
Proof of name change (if applicable): If your name has changed since your birth certificate was issued, bring a marriage certificate, divorce decree, or court order showing the change.
The written test and what it covers
The written test, also called the knowledge test, checks whether you understand traffic laws, road signs, and safe driving practices in your state. Most states offer the test on a computer at the DMV, though some still use paper. You typically have one hour to complete it, and you must pass with a score of 70 to 80 percent depending on your state.
The test covers road signs and their meanings, right-of-way rules, speed limits and when they explore, parking rules, what to do at traffic lights and stop signs, how to handle emergencies, and impaired driving laws. Many states publish a study guide or handbook online that lists the exact topics and sample questions. Reading this guide before you test is the most direct way to prepare — it's free and available on your state's DMV website.
If you fail the written test, you can usually retake it the same day or within a few days. There is typically a small fee for each retake attempt.
The driving test and how it's scored
The driving test is conducted by a DMV examiner who sits in the car with you while you drive a set route in your community. The test usually lasts 15 to 30 minutes and covers basic vehicle control, following traffic laws, and responding to road conditions. You must use your own vehicle or a vehicle belonging to someone else (the owner must be present), and the vehicle must be registered, insured, and in safe working condition.
The examiner watches for things like proper steering, smooth acceleration and braking, correct use of turn signals, safe lane changes, proper speed, and how you handle intersections and turns. Common reasons people fail include rolling through stop signs, improper lane changes, hitting the curb, speeding, and not checking mirrors and blind spots. If you fail, you can usually retake the test within a few days, though some states require you to wait a week.
Bring your learner's permit or junior license to the driving test if you have one. If you don't, bring your proof of identity documents. The examiner will also check that your vehicle's lights, wipers, horn, and brakes are working.
Fees and how long your license lasts
The cost of a new driver's license varies by state. A standard adult license typically costs between $20 and $100, with most states charging $30 to $60. Renewal fees are often lower than the cost of a new license. Some states charge extra for a REAL ID-compliant license, which is required for domestic air travel and entry to federal buildings.
Driver's licenses are valid for different lengths of time depending on your state. Most states issue licenses that last four, five, six, or eight years. Your license will show the expiration date on the front. Some states allow you to renew by mail or online if your license is not suspended and you have no major changes to report, though you may need to retake the written test every few renewal cycles.
If you already have a learner's permit or junior license
If you obtained a learner's permit or junior license before turning 18, you may not need to retake the written test when you turn 18. Many states let you skip straight to the driving test or straightforward exchange your junior license for a standard adult license without testing. However, some states still require the written test even if you hold a permit.
Contact your state's DMV or check their website to find out whether you need to test. If you do need to test, the process is the same as for someone getting a license for the first time. If you don't need to test, you can usually walk in to the DMV, pay the fee, and walk out with your new license in under an hour.
What to do if you don't have all your documents
If you're missing one of the required documents, the DMV can usually suggest alternatives. For example, if you don't have a birth certificate, you might be able to use a passport or passport card instead. If you don't have proof of residency, some states accept a letter from your school, employer, or a government agency on official letterhead.
If you don't have a Social Security number, you can obtain an ITIN from the IRS by filing Form W-7. This process takes several weeks, so plan ahead if you know you'll need one. Some states also allow you to use a tax return or other IRS document as proof of your number.
Call your state's DMV before you go in person to ask what documents they will accept in your specific situation. This saves you a wasted trip.
Frequently Asked Questions
Can I get a driver's license at 18 if I've never had a learner's permit?
Yes. You can take both the written test and the driving test as a new driver, even if you've never held a learner's permit. The process is the same — you'll need to pass both tests and bring the required documents. Some states may require you to hold a permit for a short period before taking the driving test, so check your state's rules first.
What happens if I fail the driving test?
You can retake it, usually within a few days or after a short waiting period (often one week). There is typically a small fee for each retake. Most people pass on their second or third attempt. You keep the same vehicle and examiner may test you on a similar route, so practicing the same roads can help.
Do I need to bring my Social Security card, or can I bring something else?
You need to bring proof of your Social Security number, but it doesn't have to be your card. A tax return, W-2, or other IRS document showing your number works in most states. If you don't have a Social Security number, you'll need an ITIN from the IRS instead.
How long does it take to get my license after I pass the test?
In most states, you receive your license the same day you pass the driving test. Some states mail it to you within one to two weeks. Ask the DMV before you leave whether your license will be issued on the spot or mailed.
Is a REAL ID license required, or can I get a regular license?
You can get a regular license, but a REAL ID-compliant license is required for domestic air travel and entry to federal buildings starting in 2025. A REAL ID license costs a bit more and requires additional proof of identity and residency, but it's valid for the same length of time as a regular license. Ask the DMV which option you want when you explore.
