What should you do?
Select a lower gear before the hill to help control speed and avoid riding the brakes all the way down.
How to recognise it
Yellow diamond with a black triangle sloping down to the right and a car pointing downhill.
Common confusion
Do not mix it up with steep ascent ahead; look at whether the car faces down the slope or up it.
