Engage lower gear

Where you'll see it

On the left-hand side of the road

What it means

To warn that, because of a steep descent, it is necessary to engage a lower gear

What you must do

• If you are driving a heavy motor vehicle, engage a lower gear so that the vehicle will move down the descent more slowly.
• If the lower gear does not have the desired effect, engage an even lower gear to keep the speed constant and protect the brakes against overheating.
