The knowledge test trips up many first-time applicants. Here's exactly what to study and how to walk in prepared.
The North Carolina NCDMV knowledge test has 25 questions. You must score at least 80% to pass — meaning you need at least 20 correct and can miss up to 5.
If you don't pass on your first try, you can usually retake the knowledge test the same day at many NCDMV offices, but you may be asked to come back another day depending on office policy. There is no fixed waiting period, but your $25.50 learner permit fee covers the application — you don't repay for retakes on the same application.
The test is given in person at any NCDMV driver license office. The best way to avoid long waits is to schedule an appointment online at skiptheline.ncdot.gov. Most offices don't set a time limit on the exam, and your traffic signs recognition test and vision test are given at the same visit.
All first-time applicants under 18 must complete North Carolina driver education (30 hours of classroom instruction plus 6 hours behind-the-wheel) and present a Driving Eligibility Certificate before taking the NCDMV knowledge test.
North Carolina uses DWI (Driving While Impaired). The BAC limit is 0.08% for drivers 21 and older, 0.04% for commercial drivers, and ANY measurable amount for drivers under 21 (Zero Tolerance). Know this cold — at least two questions on the test hit these numbers.
1st DWI conviction = mandatory 1-year license revocation. 2nd DWI within 3 years = 4-year revocation. 3rd DWI with one prior in the past 5 years = PERMANENT revocation. Refusing a chemical test = immediate 30-day civil revocation plus 12-month DMV revocation.
Level 1 Limited Learner Permit: age 15, driver's ed required, parent/guardian signature, held at least 9 months. First 6 months, supervised driving is 5am-9pm only. Level 2 Limited Provisional (age 16): only ONE non-household passenger under 21; unsupervised driving 5am-9pm only.
Use the two-second rule in normal conditions. Increase to four or more seconds in rain, snow, fog, behind a large truck, or when towing a trailer. Trailing too closely is a 4-point violation in North Carolina.
Default limits in North Carolina: 35 mph inside cities/towns, 55 mph outside cities/towns, 70 mph on interstates. School buses are limited to 45 mph; school activity buses 55 mph. Driving 15+ mph over a posted limit above 55 mph = 30-day revocation.
You must signal at least 100 feet before any turn or lane change — or 200 feet if the posted speed is 45 mph or more. Right turn on red is allowed after a complete stop unless a sign prohibits it; left on red is only permitted from a one-way onto a one-way.
On a 2-lane road, 2-lane with center turn lane, or 4-lane road WITHOUT a median, ALL traffic in BOTH directions must stop for a stopped school bus. On a divided highway with a physical median OR a 4-lane+ road with a center turn lane, only traffic following the bus must stop. Wait until red lights turn off AND the bus starts to move.
North Carolina law requires headlights from sunset to sunrise, when visibility is 400 feet or less, and whenever your wipers are on due to weather. High beams must illuminate a person at 200 feet; low beams at 75 feet.
No parking within 25 feet of the curb line of an intersecting street (15 feet of the right-of-way if no curb), 15 feet of a fire hydrant or fire station entrance, 100 feet of a stopped emergency vehicle, or within one block of a fire in a city (400 feet outside a city).
All occupants must wear a seat belt while the vehicle is in forward motion. Children under 8 AND under 80 lbs must be in a child passenger restraint system. Children under 5 AND under 40 lbs must ride in the rear seat if the vehicle has a rear seat and a front passenger airbag. Children under 16 may not ride in the open bed of a pickup truck.
You need 80% (20 out of 25) to pass the NCDMV knowledge test. Aim for 90%+ on every practice quiz before booking your appointment — that gives you a cushion for nerves on the real test.
Memorize BAC limits, distances, signal distance, following distances, and suspension periods. These specific numbers appear on virtually every North Carolina test.
The Weak Spots mode saves every question you got wrong. Replay it until you're hitting 90%+ before going to the NCDMV office.

The "55 outside towns, 35 inside towns" rule catches a lot of people — they expect 25 or 30 for city driving. Also note: 70 on interstates, 45 for school buses, and a 30-day revocation if you're caught going 15+ mph over a posted limit above 55 mph.
Sign questions are visual — shape, color, and meaning all matter. Use the Road Signs Quiz mode to practice all signs before test day.
