What signs appear on the written permit test
Your permit test includes questions about road signs — usually between 5 and 10 questions out of 40 to 50 total, depending on your state. The test focuses on signs that affect how you drive right now: stop signs, yield signs, speed limits, and warnings about curves or pedestrians ahead. You will not be tested on every sign that exists, only the ones that give you an instruction or alert you to danger.
Each state's test draws from the same basic set of signs, though the exact number and which ones appear can vary. Your state's driver's manual lists every sign you need to know. Most people study from that manual, not from online lists, because the manual shows you the exact signs your state uses and explains what each one means in the context of your state's traffic laws.
Key Takeaways
- Stop, yield, speed limit, and warning signs (curves, pedestrians, railroad crossings) make up most of the sign questions on permit tests across all states.
- Your state's official driver's manual is the source document for what signs appear on your test — not generic online guides.
- Signs are tested by what they tell you to do, not by their shape or color alone, so you need to understand the action each sign requires.
- Regulatory signs (red, white, black) tell you what you must or must not do; warning signs (yellow) alert you to hazards ahead.
Regulatory signs: stop, yield, and speed limits
Regulatory signs are red, white, and black, and they tell you what you must do or must not do. A stop sign is octagonal (eight-sided) and red with white lettering — you must come to a complete stop, check for traffic, and only proceed when it is safe. A yield sign is a red and white triangle pointing downward — you must slow down or stop if necessary and let other traffic pass before you go.
Speed limit signs are rectangular and white with black lettering. They show the maximum speed you are allowed to drive on that road under normal conditions. You can drive slower if conditions require it — rain, fog, heavy traffic, or construction zones all mean you should reduce speed even if the sign says 55 mph. School zone speed limits are lower and are usually in effect during specific hours; the sign will tell you those hours.
Do not pass signs, no-turn signs, and one-way signs are also regulatory. A do not pass sign means the yellow center line is solid on your side — you cannot cross it to pass another vehicle. A no-turn sign with an arrow tells you that turn is forbidden at that location. A one-way sign with an arrow tells you traffic flows in only that direction.
Warning signs: hazards and what to expect
Warning signs are yellow with black lettering or symbols. They alert you to a hazard or change in road conditions ahead — they do not order you to do something, but they tell you to be ready. A curve sign warns you the road curves sharply ahead; slow down before you reach it. A pedestrian crossing sign warns you people may be crossing the road; be prepared to stop.
Railroad crossing signs are white with a red X and black lettering. They warn you a railroad track crosses the road ahead. You must look both ways, listen for a train, and never shift gears while crossing. If crossing gates are down or lights are flashing, you must stop at least 15 feet from the nearest rail and stay stopped until the gates rise and lights stop flashing.
Other common warning signs include slippery road (skidding car symbol), hill (steep downward slope), deer crossing, and construction zone signs. Each one tells you what hazard is coming so you can adjust your speed and attention before you reach it.
Information signs: directions and services
Information signs are usually green or blue and tell you where things are or what services are available. A green sign with white lettering shows directions to cities or highways. A blue sign shows where gas, food, lodging, or hospitals are located. These signs do not test your driving knowledge — they help you navigate — but some states include one or two on the permit test to make sure you can read them.
Rest area signs and hospital signs are also information signs. You do not have to memorize them the way you memorize stop and yield signs, but you should know what they look like and what they mean so you can find services when you need them.
How to study signs for your test
Open your state's official driver's manual and look at the signs section. Read the description of each sign and what action it requires. Do not just look at the picture — read the words. Many test questions ask what a sign means or what you must do when you see it, not what the sign looks like.
Use the practice tests in your manual or on your state's DMV website. These practice tests use the same signs and the same types of questions as your real permit test. If you get a question wrong, go back to the manual and read that section again. Repeat until you can answer the question correctly and explain why that answer is right.
Some states offer online practice tests through their DMV website at no cost. Others require you to use a third-party testing site, which may charge a fee. Check your state's DMV website to find out which practice resources are available to you.
Signs you might see but probably will not be tested on
There are hundreds of signs on the road, but your permit test covers only the ones that directly affect how you drive. You will not be tested on signs for specific businesses, parking lot signs, or signs that explore only in certain situations like toll roads or carpool lanes — unless your state specifically includes those in its manual.
Focus on the signs in your state's official driver's manual. That manual is written by the people who write the permit test, so anything in it is fair game. Anything not in the manual is not your responsibility to memorize for the test.
Frequently Asked Questions
How many sign questions are on the permit test?
Most states include 5 to 10 sign questions out of 40 to 50 total questions, though this varies by state. Check your state's DMV website or driver's manual to see how many sign questions your specific test will have and which signs are covered.
What is the difference between a solid yellow line and a dashed yellow line?
A solid yellow line on your side of the road means you cannot cross it to pass. A dashed yellow line means you can pass if it is safe and no traffic is coming. These are road markings, not signs, but they appear on permit tests because they affect when you can pass another vehicle.
Do I need to memorize every sign on the road?
No. You only need to know the signs in your state's official driver's manual. That manual lists every sign you are responsible for on the permit test. Anything outside that manual is not your responsibility for the test, though learning other signs makes you a safer driver.
What should I do if I see a sign I do not recognize while driving?
If you are unsure what a sign means, slow down and be cautious. Most signs follow a pattern: red means stop or do not do something, yellow means caution, green means go or information, and blue means services. After you pass the sign safely, look it up in your driver's manual so you know what it means next time.
Can I use online sign flashcards instead of the official manual?
Flashcards can help you study, but always check them against your state's official driver's manual. Some online flashcards include signs your state does not test on, or describe signs differently than your state does. Use the manual as your source of truth and flashcards as a study tool.
