Sign Shapes โ Each Shape Has One Meaning
This is the most important thing to memorize. Even if you forget a specific sign, knowing the shape tells you what category it belongs to.

| Pennant (sideways triangle) | NO PASSING zone | Left side of road |
| Rectangle (horizontal) | Guide/information | Street names, distances |
| Rectangle (vertical) | Regulatory | Speed limit, one way |
| Crossbuck (X shape) | Railroad crossing HERE | At the tracks |
Sign Colors โ What Each Color Means
| Color | Meaning | Examples |
|---|---|---|
| Red | Stop, yield, prohibition | Stop, Yield, Do Not Enter, Wrong Way |
| White + Black | Regulatory (must obey) | Speed limit, One Way, No Turn |
| Yellow | Warning โ caution ahead | Curves, merges, signals ahead |
| Yellow-Green | Pedestrian/school warning | School zone, ped crossing |
| Orange | Construction/work zone | Road work, detour, flagger |
| Green | Guide โ direction/distance | Highway signs, exit info |
| Blue | Services | Hospital, gas, food, lodging |
| Brown | Recreation/parks | State parks, camping, hiking |
