You take one written test and one driving test to get your permit
Most states require two separate tests to earn a learner's permit: a knowledge test (written) and a driving test (behind the wheel). The knowledge test comes first and covers traffic laws, road signs, and safe driving practices specific to your state. Once you pass that, you schedule the driving test with an examiner who watches you operate the vehicle and evaluates your ability to control it safely.
Some states call these by different names — the written test might be called the permit exam, written exam, or knowledge exam, and the driving test might be called the road test, practical test, or skills test — but the structure is the same across nearly all states. You cannot take the driving test until you have passed the written test first.
Key Takeaways
- The written test covers your state's traffic laws, road signs, and safe driving rules, and you must pass it before scheduling a driving test.
- The driving test is a behind-the-wheel evaluation where an examiner watches you operate the vehicle and assesses your control and judgment.
- Some states allow you to retake a failed test the same day or within a few days; others require you to wait a week or longer before trying again.
- A few states offer a third test — a vision screening — as part of the permit process, though most include vision checks during your appointment.
What the written test covers
The written test is usually 30 to 50 questions long and covers material from your state's driver's manual. Questions test your knowledge of speed limits, right-of-way rules, parking laws, what different road signs mean, how to handle bad weather or mechanical failure, and what to do at traffic lights and stop signs. The test is multiple choice, and you typically need to answer 70 to 80 percent of questions correctly to pass.
You take the test on a computer at your local DMV office, and it usually takes 20 to 30 minutes. Some states allow you to take the test in languages other than English — check your state DMV website for which languages are available in your area. If you fail, most states let you retake it within a few days or the same day, though a few require a waiting period of one to two weeks.
What the driving test covers
The driving test lasts 15 to 30 minutes and takes place on public roads or a closed course, depending on your state. An examiner sits in the passenger seat and watches you perform basic vehicle operations: starting the car, steering, braking, accelerating, turning, parking, and backing up. They also observe how you respond to traffic signals, pedestrians, and other vehicles, and whether you check your mirrors and blind spots.
You must bring your own vehicle (or use one provided by the testing facility in some states), proof of insurance, and your learner's permit. The examiner will ask you to perform specific maneuvers — such as parallel parking, a three-point turn, or merging into traffic — and will note any safety violations or control problems. If you fail, you can usually retake the test within one to two weeks, though some states allow same-day retesting.
Vision screening and other preliminary checks
Most states include a vision test as part of your permit appointment, though it is not always counted as a separate "test" you can pass or fail. The vision screening checks whether you can read an eye chart at a certain distance and whether you have adequate peripheral vision. If you fail the vision screening, you may be required to get a corrective lens restriction on your permit, or you may need to bring a vision correction certificate from an eye doctor before the DMV will issue your permit.
A few states also conduct a brief hearing test during the appointment, though this is less common. Some states require a medical form signed by a doctor if you have certain conditions (such as epilepsy or severe hearing loss), but this is not a test you take at the DMV — it is documentation you bring with you.
Retesting rules and waiting periods
If you fail the written test, most states allow you to retake it within three to seven days. A few states impose a longer waiting period — up to two weeks — or charge an additional fee for each retake. Check your state DMV website for the specific retesting policy, because it varies.
For the driving test, retesting windows are usually one to two weeks, though some states allow you to schedule a retest when ready if you fail. A small number of states charge a retest fee (usually $5 to $15) in addition to the original test fee. If you fail the driving test twice, some states require you to take a driver education course before you can test again, though this is uncommon for permit-level testing.
State-by-state differences in test structure
Most states follow the two-test model (written and driving), but a few have variations. Some states offer a third-party testing option, where you can take your driving test through a private testing facility instead of the DMV, though you still take the written test at the DMV. A handful of states allow you to take the written test online from home, while others require you to test in person at an office.
A few states have a graduated licensing system with multiple permit stages — for example, a learner's permit stage and then a restricted license stage — each with its own requirements. In those states, you may take additional tests when you move from one stage to the next. Check your state DMV website to see whether your state uses a graduated system and what that means for your testing timeline.
How to prepare for both tests
For the written test, study your state's driver's manual (available free on your state DMV website) and take practice tests online. Most state DMV websites offer free practice exams that mirror the real test in format and difficulty. Spend at least a week reviewing the manual and taking practice tests before your appointment.
For the driving test, practice with a licensed adult in your state for the number of hours required by your state's learner's permit rules — this is usually 20 to 50 hours of supervised driving. Practice in different weather and traffic conditions, and focus on the specific maneuvers the examiner will ask you to perform (parallel parking, three-point turns, merging). On test day, arrive early, bring all required documents, and get a good night's sleep beforehand.
Frequently Asked Questions
Can I take the written test and driving test on the same day?
In most states, no — you must pass the written test first, then schedule the driving test for a later date. A few states allow same-day testing if you pass the written exam in the morning and a driving test slot is available that afternoon, but this is rare. Contact your local DMV to ask whether same-day testing is an option in your area.
What happens if I fail both tests?
You can retake each test separately according to your state's retesting rules. Failing the written test does not prevent you from retaking it; failing the driving test does not prevent you from retaking it. However, if you fail the driving test multiple times (usually after two or three attempts), some states require you to complete a driver education course before testing again.
Do I have to take a vision test at the DMV?
Most states include a vision screening as part of your permit appointment. If you fail the vision screening, you may need to bring a corrective lens prescription or a letter from an eye doctor. A few states allow you to bring vision documentation in advance to avoid delays on test day.
Is there a written test for a motorcycle permit?
Yes. Most states require a separate written test for a motorcycle permit that covers motorcycle-specific rules, handling, and safety. You may also need to take a motorcycle-specific riding test, or you may be able to take a motorcycle safety course in place of the riding test — rules vary by state.
How long is each test?
The written test usually takes 20 to 30 minutes. The driving test usually takes 15 to 30 minutes, depending on the route and the number of maneuvers the examiner asks you to perform. Arrive at your appointment 15 minutes early to allow time for check-in and paperwork.
