North Carolina DMV Permit Test: Sign Shapes, Colors, and Regulatory Signs Concepts
Importance ★★★★★ · 45% (estimate)
Overview
North Carolina gives a separate road sign test, and you must identify each sign by its color and shape and say what it means. This chapter covers the signs that state rules you must obey and the shapes and colors that tell you what kind of sign you are looking at.
Shape comes first. The eight-sided sign is used only for STOP, and the triangle with its point at the bottom is used only for YIELD. Rectangles and squares, usually black on white or red on white, show speed limits and other rules, such as NO U-TURN or KEEP RIGHT EXCEPT TO PASS. A red circle with a slash over a picture means the action shown is not allowed.
At a STOP sign you must come to a full stop at the stop line. If there is no stop line or crosswalk, stop before entering the intersection at a point where you can see the cross street. At a YIELD sign, slow down and let traffic on the other road go first, and stop if you need to. On a steady red light you may turn right after a full stop unless a NO TURN ON RED sign is posted.
Key concepts
STOP sign
A red eight-sided sign with white letters. The eight-sided shape is used for no other sign. You must come to a full stop and not move again until the way is clear.
Memory tipEight sides: stop all the way, every time.
Where to stop
Stop at the marked stop line. If there is no stop line or marked crosswalk, stop before you enter the intersection, at a point where you can see the cross street.
Memory tipLine first, then crosswalk, then the edge where you can see.

YIELD sign
A red and white triangle with the point at the bottom. Slow down and give the right of way to traffic on the other road. Stop and wait if that traffic is close.
Memory tipPoint down: let the other traffic go first.
Rule signs
Rectangular or square signs, normally black and white or red and white, that show speed limits and other rules such as NO U-TURN or KEEP RIGHT EXCEPT TO PASS. Ignoring them breaks traffic law.
Memory tipWhite rectangle: a rule, not advice.
Red circle and slash
A red circle with a slash over a symbol means the action in the symbol is not allowed, such as a left turn or a U-turn.
Memory tipSlash through it: do not do it.
Right turn on red
On a steady red light you may turn right after a complete stop unless a NO TURN ON RED sign is posted. You must yield to traffic and to pedestrians in or near the crosswalk.
Memory tipFull stop, look, then turn, unless the sign says no.

3 sample questions
Verified practice questions from this unit.
Question 1. What must you do when you come to this sign?
- ① Slow down and let traffic on the other road go first, stopping only if needed
- ② Stop only if a police officer is present
- ③ Come to a full stop every time, even if no one is coming
- ④ Speed up to merge ahead of the other traffic
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① Slow down and let traffic on the other road go first, stopping only if needed
Key point: Yield sign: slow down, give way, stop only if needed
This red and white triangle with its point at the bottom is the YIELD sign. Slow down and give the right of way to traffic on the road you are entering. If that traffic is close, stop and wait for it to pass.
Wrong choices
- Come to a full stop every time, even if no one is coming: A full stop every time is required at a STOP sign, not a YIELD sign.
- Speed up to merge ahead of the other traffic: Speeding up to cut in front of traffic is the opposite of yielding.
- Stop only if a police officer is present: The sign applies at all times, whether or not an officer is there.
Question 2. Which sign shape is used only for STOP signs?
- ① Diamond
- ② Triangle
- ③ Octagon (eight sides)
- ④ Pentagon (five sides)
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ Octagon (eight sides)
Key point: Eight-sided octagon = STOP only
The octagon, a sign with eight sides, is used only for STOP signs. You can know it is a STOP sign from its shape even from behind or when it is covered with snow.
Wrong choices
- Triangle: The triangle with its point down is used for YIELD.
- Diamond: Diamonds are used for warning signs.
- Pentagon (five sides): The five-sided shape is used for school zone and school crossing signs.
Question 3. When you reach a STOP sign, what does the law require?
- ① Stop only at night
- ② Slow down and roll through if no one is coming
- ③ Come to a full stop and go only when the way is clear
- ④ Stop only if there are pedestrians
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ Come to a full stop and go only when the way is clear
Key point: STOP sign: full stop every time
At a STOP sign the law requires a full stop. Do not move again until you are sure the way is clear.
Wrong choices
- Slow down and roll through if no one is coming: Rolling through without stopping is illegal even if the road looks empty.
- Stop only if there are pedestrians: You must stop whether or not people are crossing.
- Stop only at night: The sign applies at every hour of the day.
