Q #254 - Your vehicle is stationary. When may you use its horn?
When your vehicle is stationary, only sound the horn if you think there's a risk of danger from another road user. Don't use it just to attract someone's attention. This causes unnecessary noise and could be misleading.
| When another road user poses a danger | |
| When the road is blocked by queuing traffic | |
| When it's used only briefly | |
| When signalling that you've just arrived |
