Preparing for the North Carolina Knowledge, Sign and Vision Tests

Before you study: three tests, not one

According to the handbook, you clear each exam on its own merits. The permit involves three: eyes, signs and the written rules test. Driving comes much later, once the permit has been held long enough.

A strong knowledge score will not rescue a weak sign test, and the reverse is also true. Study both, and bring your glasses or contacts, because needing them to pass the vision check adds a corrective lens restriction to the permit.

Before you study: how the knowledge test is scored

NCDMV's sample test page describes the official Driver Knowledge Test as 25 questions drawn from 100, with 20 correct needed. Eighty percent is a higher bar than many states set, leaving room for only five misses.

Questions cover traffic laws and safe driving. Since they come from a bank of 100, two applicants on the same day can see different questions, which is why learning the handbook beats memorizing one practice set. NCDMV publishes no time limit.

While studying: the wordless sign test

This is the part that catches people out. You are shown regulatory and warning signs by color and shape and asked what each means: an octagon, a pennant, a pentagon, a diamond, with nothing written on them.

For practice, NCDMV publishes a sheet of regulatory signs and a sheet of warning signs, and the handbook promises that nothing on the sign test falls outside its pages. Start with the anchors it gives: only stop signs are octagons, a yellow pennant warns of a no passing zone, diamonds mean caution or warning, and a pentagon marks a school zone or crossing.

While studying: which chapters carry the questions

The current handbook is 108 pages in seven chapters, and the PDF on NCDMV's site was updated in September 2026. Chapter 1 is about licenses and documents, useful for your visit but rarely tested.

Most knowledge questions come from three places: Chapter 2 (alcohol and the law), Chapter 4 (your driving, which fills roughly 40 of the 108 pages) and Chapter 6 (how to share space with people on foot, bikes, motorbikes and mopeds, plus big trucks and school buses). Chapter 5, on signals, signs and markings, feeds both tests.

• Ch. 1, the license itself: rarely tested
• Ch. 2, alcohol and the law: tested
• Ch. 3, points and suspensions: background
• Ch. 4, how to drive: the biggest source of questions
• Ch. 5, signals, signs and markings: both tests
• Ch. 6, sharing the road: tested
• Ch. 7, DMV services: background

While studying: NCDMV's practice set

On NCDMV's website there is a brief quiz in the real test's style that scores you at the end. Every question must be answered before it will grade.

The set is short, so treat it as a format check, not a full rehearsal. After each try, look up the rule behind each miss in Chapter 4 or 5, and drill the sign sheets until every shape is instant.

On test day: language help and interpreters

NCDMV says the written test comes in different languages and oral tests are available on request, and the handbook notes audio tests for people who struggle with reading. Ask your office which languages it offers before you go.

NCDMV provides interpreters, both ASL and spoken language, for customers who are deaf or hard of hearing, have a speech disability, or are still learning English. Ask through the request form on NCDMV's site, or phone (919) 715-7000 on a weekday between 8 and 5. Have ready your name and how to reach you, your county, which office you plan to use, and what kind of interpreter you need.

If you fail, and how teens and adults differ

The exams do not change with age; the entry requirements do. A 15 to 17 year old needs the driver ed certificate and a parent or guardian in tow for Level 1, while someone 18 or over simply applies for an ordinary permit.

Fail the written test, or later the driving test, for a regular Class C, and NCDMV makes you wait a full week (seven calendar days) before trying again. Use that week on the sections you missed. New to North Carolina with a valid out-of-state license? Ask the office which of the three tests you still need before booking.
