How to recognise the steep ascent sign
A triangle showing a steep uphill gradient.
Where you will see it
On roads where the road climbs steeply, especially in mountains.
What to do when you see it, step by step
- Select the right gear early and expect slow-moving traffic.
The common mistake
Do not cross a no-overtaking line on the climb to pass a slow vehicle.
Why this sign matters
A steep climb slows vehicles, and slow traffic bunches up behind them. The sign helps you choose the right gear and expect queues.
About warning signs
Warning signs tell you about a hazard ahead so you can slow down and prepare. They are red-bordered triangles. The K53 learner's test asks you to recognise signs like the steep ascent sign (W323) and choose the correct response, so learn both the picture and the action.
How to answer a test question about this sign

- Recall what the sign asks of you: select an appropriate gear and expect slower heavy vehicles.
- Remove the options that describe a different group of sign, then choose the response that matches the action.
