Shapes and colours to know
You can often tell what kind of sign it is before you can read it. That matters at the test — and even more on a snowy day when a sign is half covered.
| Sign | What it looks like |
|---|---|
| Stop | Eight-sided, red with white letters. Come to a complete stop. |
| Yield | Triangle pointing down, white with a red border. |
| School zone | Five-sided, fluorescent yellow-green with black symbols. |
| Railway crossing | X-shaped, white with a red outline. |
| Regulatory | Usually rectangular or square, white or black background. A green circle means you may or must do it; a red circle with a line through it means you can’t. |
| Warning | Usually diamond-shaped, yellow with black letters or symbols. |
| Temporary conditions | Usually diamond-shaped, orange with black letters or symbols — road work, detours, lane closures. |
| Information and direction | Usually rectangular, green with white letters — distances and destinations. |
| Slow-moving vehicle | Orange triangle with a red border, on vehicles that travel 40 km/h or less. |
