Shapes and what they mean
| Shape | What it tells you |
|---|---|
| Eight-sided (red) | STOP. Come to a full stop at the limit line. No line? Stop before the crosswalk, or before the intersection if there’s no crosswalk either. |
| Upside-down triangle (red and white) | YIELD. Slow down and be ready to stop for vehicles, bikes or people walking. |
| Five-sided | There’s a school nearby. Drive slowly and stop for children in the crosswalk. |
| Diamond | A warning about the road or a hazard ahead. |
| Round (yellow and black) or X-shaped | A railroad crossing is coming. Look, listen, slow down and be ready to stop. |
| Red circle with a line through it | Whatever’s pictured inside isn’t allowed. |
| White rectangle | A rule you have to follow, like a speed limit or ONE WAY. |
What the colors tell you
Obey every warning sign, whatever its shape or color. The handbook is clear on that.
- Red and white: an order, such as STOP, YIELD, DO NOT ENTER or No U-Turn
- Black on white: a rule, such as NO PARKING ANY TIME or ONE WAY
- Yellow: a warning, such as a curve, a merge, a lane ending or a signal ahead
- Orange: road work and maintenance zones
- Green: guide signs that point you to places and routes
- Blue and white at a railroad crossing: what to do if your car stalls on the tracks or there’s an emergency
If you’ve gone the wrong way
DO NOT ENTER and WRONG WAY signs mean you’re driving against traffic. When it’s safe, back out or turn around. At night there’s another clue: road reflectors shine red in your headlights when you’re going the wrong way.
Signs on vehicles count too
An orange triangle with a red border on the back of a vehicle marks it as slow-moving, usually 25 mph or less. Give it room and expect to slow down behind it.
