Road signs chart: every shape and color.
U.S. road signs follow one federal standard, so this chart works for every state's permit test. Print it, stick it on the fridge, and quiz yourself with the free practice test linked below.
Prefer testing yourself first? Take the free road signs practice test — this chart is the answer key.
Sign shapes and what they mean
| Shape | Meaning | Example |
|---|---|---|
| Octagon (8 sides) | Stop. The only octagon on the road. | STOP |
| Triangle, point down | Yield right-of-way. Slow down and give traffic the go-ahead. | YIELD |
| Vertical rectangle | Regulatory notice — a law you must follow at that spot. | SPEED LIMIT 55 |
| Pennant, sideways | No-passing zone begins here — it marks the left side of the road. | DO NOT PASS |
| Diamond | Warning about conditions ahead. | MERGE / SIGNAL AHEAD |
| Pentagon, point up | School zone or school crossing. | SCHOOL |
| Round (circle) | Railroad crossing ahead. | RR CROSSING AHEAD |
| Crossbuck (X) | Railroad crossing at the tracks themselves — yield to trains. | RAIL ROAD CROSSING |
| Shield | Route marker — the highway number you are on. | INTERSTATE 40 |
Sign colors and what they mean
| Color | Used for |
|---|---|
| Red | Stop, yield, or prohibition: stop, yield, do not enter, wrong way. |
| White with black text | Regulatory laws such as speed limits and turn restrictions. |
| Yellow | General warning of a change in road conditions ahead. |
| Fluorescent yellow-green | School, pedestrian, and bicycle warnings — the highest-visibility warning color. |
| Orange | Construction and maintenance zones. Slow down; fines often double. |
| Green | Guidance: directions, distances, exits. |
| Blue | Motorist services: rest areas, hospitals, fuel, police. |
| Brown | Recreation and cultural-interest areas: parks, campgrounds, historic sites. |
Ten signs that show up on nearly every permit test
- StopFull stop at the line, crosswalk, or before entering the intersection — then proceed when clear.
- YieldGive the right-of-way; slow and be ready to stop for traffic already on the road you join.
- Do Not EnterYou may not drive past this sign — typically a one-way street or ramp in the wrong direction.
- Wrong WayYou are traveling against traffic. Pull over safely, then turn around.
- One WayTraffic flows only in the direction of the arrow.
- No Passing ZoneThe stretch ahead cannot be used for passing — stay in your lane until a passing zone returns.
- Signal AheadA traffic light is ahead; be prepared to stop.
- MergeTraffic joins from another road; adjust speed and share the lane.
- Slippery When WetReduce speed in rain — the surface loses traction when wet.
- Divided Highway BeginsThe road splits; keep right of the divider.
How to memorize the chart
Learn shapes and colors before individual signs: an octagon always means stop and a downward triangle always means yield, so you can guess correctly even on a sign you have never seen. Then drill retrieval — look away, redraw the table from memory, and check yourself.
