The sign test is a separate part of North Carolina's written knowledge exam

North Carolina splits its written test into two parts: the general knowledge test and the road sign test. You take both on the same day at the DMV, but they measure different things. The general knowledge test covers rules of the road — speed limits, right-of-way, parking. The sign test shows whether you can recognize and understand the actual signs you'll see while driving.

The sign test comes second, after you finish the general knowledge portion. You'll answer questions about real road signs: what they mean, what color they are, and what you should do when you see them. The test uses images of actual signs you encounter in North Carolina.

You need to pass both parts to pass the overall written exam. If you fail one part, you can retake the entire test, but you don't retake just the section you missed.

Key Takeaways

  • North Carolina's sign test shows images of real road signs and asks what they mean, what action to take, or what color they are.
  • You answer between 15 and 20 questions about signs on a computer screen at the DMV testing station.
  • Common signs on the test include stop signs, yield signs, speed limit signs, warning signs (like curves ahead or pedestrian crossing), and regulatory signs (like no parking or one-way).
  • You must score at least 80 percent on the sign test to pass; missing more than 4 questions out of 20 means you fail that section.
  • The sign test is included in your one written exam appointment — you do not schedule it separately.

How many questions and what score you need

The sign test contains between 15 and 20 questions. Each question shows you a sign image and asks one of three things: what the sign means, what you should do when you see it, or what color it is. The questions are multiple choice with four answer options.

You must score at least 80 percent to pass. That means if there are 20 questions, you can miss no more than 4. If there are 15 questions, you can miss no more than 3. The exact number of questions varies, but the 80 percent threshold stays the same.

What signs appear on the North Carolina sign test

The test focuses on signs you will actually encounter while driving in North Carolina. These fall into a few categories: regulatory signs (red and white, or black and white), warning signs (yellow and black), and informational signs (green and white, or blue and white).

Regulatory signs tell you what you must or must not do. Stop signs, yield signs, speed limit signs, no parking signs, one-way signs, and do-not-enter signs all appear on the test. You need to know what action each one requires.

Warning signs alert you to hazards or changes ahead. Curve ahead, pedestrian crossing, school zone, slippery when wet, hill or steep grade, and railroad crossing signs are common. The test asks what danger or condition the sign warns about.

Informational signs provide directions or services. Highway route signs, exit signs, rest area signs, and hospital signs may appear. You should know what information they give you.

How the test is delivered at the DMV

You take the sign test on a computer at the DMV testing station, the same way you take the general knowledge test. The questions appear one at a time on the screen. Each question shows a color image of a sign and four answer choices below it.

You use the keyboard or mouse to select your answer and move to the next question. You cannot go back to change an answer once you move forward. The test does not show you a countdown timer, but you have a reasonable amount of time per question — there is no speed pressure.

After you finish the sign test, the computer when ready scores both parts of your written exam and tells you whether you passed or failed. If you pass, you move on to scheduling your road test. If you fail either section, you must retake the entire written exam.

How to study for the sign test

The North Carolina DMV publishes a free Driver's Handbook that includes a section on road signs with images and meanings. This handbook is available on the DMV website and covers every sign type that appears on the test. Reading through the sign section once or twice before your test is the most direct way to prepare.

You can also study using online practice tests. Many third-party websites offer free North Carolina sign practice questions with images. These are not official DMV tests, but they use real sign images and similar question formats. Taking a few practice tests helps you get comfortable with the computer interface and the types of questions asked.

Focus your study on the sign categories listed above: regulatory, warning, and informational. Learn what each sign looks like, what color it is, and what action or information it conveys. Most people who study the handbook and take one or two practice tests pass the sign section without trouble.

What happens if you fail the sign test

If you fail the sign test (or the general knowledge test), you must retake the entire written exam. You cannot retake just the sign portion. You will need to schedule a new appointment at the DMV and pay the test fee again.

North Carolina allows you to retake the written test as many times as you need, but you must wait at least one day between attempts. Most people pass on the second try after studying the areas where they struggled. There is no limit to how many times you can test.

If you fail, ask the DMV staff which types of signs gave you trouble. Then focus your next study session on those categories. The handbook breaks signs down by type, so you can drill the ones you missed.

Frequently Asked Questions

Can I use the DMV handbook to study for the sign test?

Yes. The North Carolina DMV Driver's Handbook includes a full section on road signs with color images and explanations. It is free and available on the DMV website. This handbook covers all signs that appear on the test.

Do I have to memorize the exact color of every sign?

You should know the general color scheme of sign categories — stop signs are red and white, warning signs are yellow and black, informational signs are green or blue and white. The test does ask about sign colors, but usually as part of a question about what the sign means, not as a standalone question.

What if I fail the sign test but pass the general knowledge test?

You must retake both parts together. North Carolina does not let you retake just one section. Schedule a new appointment, pay the test fee again, and take the full written exam. You can retake it the next day if you want to.

How long does the sign test take?

The sign test usually takes 5 to 10 minutes, depending on how many questions appear and how quickly you answer. The general knowledge test takes longer — usually 20 to 30 minutes. Both are part of one appointment.

Are the signs on the test the same as the ones in the handbook?

Yes. The test uses real sign images, and the handbook shows the same signs. Studying the handbook directly prepares you for the images and questions you will see on test day.
