The steep hill upwards sign warns drivers of a sharp ascending gradient ahead. Climbing steep hills requires selecting lower gears to maintain momentum.
This sign alerts drivers to potential slow-moving heavy goods vehicles ahead, as well as the risk of rolling backwards when stopping.
What this sign means
It warns that the road ascends sharply ahead, which can significantly affect vehicle speed and performance.
- Red warning triangle with upward slope symbol left-to-right
- May include gradient ratios or percentage values
- Alerts to potential slow traffic ahead
What to do when you see it
Select a lower gear early to maintain engine power and momentum as you climb. Leave extra space behind large vehicles ahead.
- Shift to a lower gear before losing momentum
- Anticipate slow-moving lorries or cyclists
- Be prepared to use the handbrake for hill starts if traffic stops
How this sign is tested
Theory questions test knowledge on engine performance, gear selection, and safe follow distances behind heavy vehicles on inclines.
Common mistakes
Remaining in too high a gear, causing the engine to labour or stall mid-climb.

Practise road sign questionsFrequently asked questions
Why should I drop back behind large lorries climbing hills?
Large vehicles lose speed rapidly on steep climbs and may roll back slightly when pulling away.
Does a steep hill upwards affect fuel consumption?
Yes, driving uphill in lower gears requires more engine power and consumes more fuel.
What should I do if I am forced to stop on a steep hill?
Apply the parking brake immediately to prevent rolling backward before pulling away smoothly.
