How to recognise the road narrows sign
A triangle showing the road narrowing symmetrically from both sides.
Where you will see it
On any road before a narrowed section.
What to do when you see it, step by step
- Slow down and move your position on the carriageway, because oncoming vehicles will pass close to you.
The common mistake
It narrows both ways, unlike W329 and W330 where one side only closes in.
Why this sign matters
When both sides of the road close in, vehicles pass closer together. The sign asks you to slow and give oncoming traffic room.
