Road signs on your learner's permit test cover three main categories: warning signs (yellow diamonds), regulatory signs (red and white rectangles), and information signs (green rectangles)
Your permit test will ask you to identify signs and understand what they mean. The test focuses on signs you'll actually see while driving, not every sign that exists. Most questions show you a picture of a sign and ask what it means, or describe a situation and ask which sign applies. You need to know the shape, color, and message of each sign because that combination tells you whether it's a command, a warning, or just information.
The signs tested vary slightly by state, but the core ones are the same everywhere. This guide covers the signs that appear on most state permit tests. Your state's DMV handbook lists the exact signs your test will include — check that before you study, because some states add regional signs or skip ones others use.
Key Takeaways
- Warning signs are yellow diamonds and alert you to hazards ahead, like curves, pedestrians, or school zones.
- Regulatory signs are red or white rectangles and give commands you must follow, like speed limits and stop signs.
- Information signs are green rectangles and tell you where things are, like exits, hospitals, or rest areas.
- Shape and color matter as much as the words on the sign — a red octagon always means stop, regardless of what you're stopping for.
- Your state's DMV handbook shows the exact signs your test covers, so use that as your study list rather than a generic one.
Warning signs: yellow diamonds that tell you what's coming
Warning signs are always yellow with black text or symbols, and they're always diamond-shaped. They don't command you to do anything — they tell you to be ready for something. A curve ahead sign warns you the road will turn sharply. A pedestrian crossing sign warns you people may be in the street. A school zone sign warns you children may be present.
Common warning signs on permit tests include curves, hills, slippery road, pedestrian crossing, bicycle crossing, school zone, railroad crossing, and divided highway ending. When you see a yellow diamond on the test, the question is almost always "what should you do?" The answer is usually "slow down" or "be prepared to stop." You won't be commanded to stop by a warning sign — you're just told to expect something and adjust your speed or attention.
One warning sign that confuses test-takers is the divided highway ending sign. It shows two lanes merging into one and warns you that traffic from the opposite direction is about to appear. You need to slow down and be ready to see oncoming traffic, but you're not stopping — you're preparing.
Regulatory signs: red and white rectangles that give commands
Regulatory signs tell you what you must or must not do. They are red, white, or black, and they are rectangles or octagons. A stop sign is a red octagon. A yield sign is a red triangle. A speed limit sign is a white rectangle. A no-entry sign is a red rectangle with a white horizontal bar. These signs are laws — you break them at your own risk.
The most common regulatory signs on permit tests are stop, yield, speed limit, do not enter, no passing, no turn on red, and one-way. Stop means you must come to a complete stop. Yield means you must slow down and let other traffic go first, but you don't have to stop if the road is clear. Speed limit tells you the maximum speed for that road. Do not enter means the road is closed to you — usually because you're heading the wrong way on a one-way street.
A no passing sign means you cannot cross the center line to pass another vehicle. A no turn on red sign means you cannot turn right at a red light, even if the road is clear — you must wait for green. These signs are straightforward to spot on a test because they use the word "no" or show a red circle with a slash through a symbol.
Information signs: green rectangles that show locations and directions
Information signs are green with white text and are always rectangles. They tell you where things are: exits, hospitals, rest areas, gas stations, lodging, or scenic areas. They also show distance and direction. An exit sign tells you which highway exit is coming up. A hospital sign with an arrow tells you which way to go to reach one. These signs don't command you — they inform you.
On a permit test, information sign questions usually ask you to identify what the sign means or where it directs you. You won't be tested on every information sign, but you should know the common ones: exit, hospital, rest area, gas station, food, and lodging. The color green is the key — if you see green on the test, it's telling you where to go, not what to do.
How to study signs by category instead of memorizing a list
Instead of trying to memorize every sign, learn the system: shape and color tell you the category, and the category tells you what the sign does. Yellow diamond = warning = be ready. Red or white rectangle = regulation = follow the rule. Green rectangle = information = know where things are. This system works for almost every sign you'll see.
When you study, cover the words on the sign and look only at the shape and color. Ask yourself: "Is this telling me to do something, warning me about something, or showing me where something is?" Once you answer that, the specific meaning becomes easier to guess even if you don't remember the exact sign. On test day, this skill will help you answer questions about signs you've never seen before.
Practice tests are the best way to learn signs because they show you the actual pictures and the actual questions. Take a practice test, mark the signs you missed, then study only those. Your state's DMV website usually has a free practice test, and many have multiple versions so you can take them several times.

| Speed Limit | White rectangle | Do not drive faster than this speed |
| Do Not Enter | Red rectangle with white bar | You cannot go this way |
| Curve Ahead | Yellow diamond | Road will turn sharply; slow down |
| Pedestrian Crossing | Yellow diamond | People may be crossing; be ready to stop |
| School Zone | Yellow diamond or rectangle | Children present; obey reduced speed limit |
| Exit | Green rectangle | Highway exit ahead |
| Hospital | Green rectangle with H | Hospital in this direction |
| No Passing | White rectangle with red slash | Do not cross center line to pass |
Common mistakes test-takers make with road signs
The most common mistake is confusing stop and yield. Both are red, but stop is an octagon (eight sides) and yield is a triangle (three sides). Stop means you must stop completely. Yield means you must let traffic go first, but you can go if it's clear. On the test, if the question asks "what must you do?" and shows a red triangle, the answer is yield, not stop.
Another common mistake is not reading the words on regulatory signs carefully. A sign might say "no left turn" or "no right turn on red" — the word "no" and the specific direction matter. If you only remember "no turn," you'll get the question wrong. Read the full sign every time.
A third mistake is assuming all yellow signs are warnings. Most are, but some yellow signs are regulatory — like school zone signs in some states. Check the shape and read the words to be sure. If you're unsure, your state's DMV handbook will clarify.
Frequently Asked Questions
Will my permit test show me the actual sign or just describe it?
Most permit tests show you a picture of the actual sign. Some questions describe a situation and ask which sign applies. Either way, knowing the shape and color helps you answer even if you don't remember the exact wording. Practice tests on your state's DMV website will show you the exact format your test uses.
Do I need to memorize every sign, or just the main ones?
You need to know the main ones your state tests. Your DMV handbook lists them. Most states test 15 to 25 signs, not hundreds. Focus on those first, then learn others if you have time. A practice test will show you which ones your state emphasizes.
What if I see a sign on the test I've never studied?
Use the shape and color system. Yellow diamond = warning. Red octagon = stop. Green rectangle = information. If you know the category, you can often guess the meaning. Also, most permit tests only ask about signs in the official handbook, so this situation is rare if you study from your state's materials.
Are road signs the same in every state?
The main signs are the same everywhere — stop, yield, speed limit, and warnings look identical across the country. Some states add regional signs or use slightly different wording. Your state's DMV handbook shows exactly which signs your test covers, so use that as your study guide rather than a generic one.
How many questions about road signs will be on my permit test?
Most states include 5 to 10 road sign questions on the permit test, though this varies. Your state's DMV website usually says how many questions are on the test and how many you need to pass. A practice test will give you the exact breakdown for your state.
