NC DMV Knowledge Test: What to Expect on Test Day

Walking into the DMV for the first time is easier when you know the order of things. At a North Carolina driver license office you go through check-in, a vision test, a road sign test and a 25-question knowledge test. You need 20 correct answers on the knowledge test and 9 of 12 on the signs. This page walks you through the visit from the door to the result, and tells you what to bring and how to prepare.

The visit, step by step

1. Check-in. A clerk reviews your documents and starts your application.
2. Vision test. A quick check of your eyesight.
3. Road sign test. 12 signs, 9 must be correct.
4. Knowledge test. 25 multiple-choice questions on a computer, 20 must be correct.
5. Result and payment. If you pass, you pay and you get your permit.

The NCDMV lets you book an appointment up to seven days ahead at skiptheline.ncdot.gov. Driver license offices also take walk-ins all day, from open to close, until the office reaches capacity. Most offices are open from 8:00 a.m. to 5:00 p.m., and hours can vary by location. In the Charlotte area, see the offices and how to book.

Check-in: what the clerk looks at

Before any test, the clerk checks that your paperwork is complete. A missing document is the most common reason for a wasted trip, and no amount of studying fixes it. See "What to bring" below, and the full list on our page of NC driver's license requirements.

The vision test

You need 20/40 vision or better in at least one eye, or in both eyes together. Glasses and contacts are allowed. If you need them to see, that is noted as a restriction on your license. If your vision is below 20/40, you may need a Vision Specialist form (DL-77) to apply for a restricted license.

The road sign test

This is a separate test from the 25 questions. You are shown 12 signs and must say what each one means. The signs are recognized by shape and color. For a regular Class C license, you need 9 of the 12 correct, so you can miss 3 (19A NCAC 03B .0201).

The practical lesson is that you need to know a sign by its outline, not only by the words printed on it. An octagon is a STOP sign. A downward-pointing triangle is YIELD. A diamond is a warning. Red means stop or prohibition, yellow warns, orange means a work zone, and green guides. Practice with our road sign test page.

The knowledge test

• 25 multiple-choice questions about traffic laws and safe driving practices.
• 20 correct answers to pass (80%). You can miss 5.
• On a computer at the office.
• No strict time limit. Read each question calmly.

The NCDMV says the knowledge test is offered in different languages and that oral tests are available on request. Audio tests are also available on request for people who have difficulty reading. Ask when you book or when you check in.

The questions come from the rules in the official NC Driver Handbook. No DMV publishes its real question bank, so be wary of any site that claims to sell the questions from the live test. For the full breakdown, see how many questions are on the NC DMV test.

What if you fail

You can try again. The rules:

• Wait 7 calendar days before you retake the test. These are consecutive days, not business days.
• Offices commonly allow up to 3 attempts within 90 days of your application. Confirm the details at your office, because practice can vary.
• After 3 failures, or when the 90 days are up, the application closes and you start the process over, with documents and payment.

The permit fee, $25.50, is paid after you pass. The current amount is on ncdot.gov. Details are in how much the NC permit costs. For a plan to use the week of waiting, read what to do if you failed the NC DMV test.

What to bring

For an adult applicant, the NCDMV asks for:

• Proof of identity and age: for example a certified birth certificate, a valid U.S. passport, a Permanent Resident Card, an Employment Authorization Document or a naturalization certificate.
• Proof of your Social Security number: the original card, or a W-2, a 1099 or a pay stub showing the full number. If you are not eligible for an SSN, bring U.S. government documents that prove your legal presence.
• Two proofs of North Carolina residency: two different documents with your name and NC address, such as a utility bill, a bank statement or a lease. Recent ones are best, ideally from the last 60 to 90 days.
• Proof of liability insurance for a new license. You can bring it printed or upload a digital copy at the office.

Bring originals. Requirements can change, so check ncdot.gov before you go.

How to prepare

1. Read the official NC Driver Handbook. It is free, and a summary is on our handbook page.
2. Take the free 25-question practice test to see the format.
3. Practice the signs by shape and color, with no words, until you can name them quickly.
4. Go through the 400 practice questions with explanations, and read the 10 most common mistakes on the NC DMV test.
5. Sleep well the night before. Cramming at the last minute does not help.

Our questions are practice questions based on the official handbook. They are not the questions on the real test, and no study material can guarantee you will pass. Driver-Prep is an independent educational project and is not affiliated with the NCDMV.
