Driving on Hills
Hills
Understanding how hills affect vehicle control is key to safe driving.
Uphill Driving
When driving uphill:
-
The engine works harder to overcome gravity.
-
You may need to change to a lower gear to maintain speed.
-
Always change gears promptly to avoid losing momentum.
-
Apply the parking brake when stopped to prevent rolling back.
Watch for gradient warning signs — the higher the percentage, the steeper the hill.
Anticipate slow-moving vehicles and plan overtakes with care.
Tip: Avoid turning and climbing at the same time — change down before the bend for better control.
Going Downhill
When descending:
-
Gravity increases your speed — braking becomes less effective.
-
Avoid coasting (clutch down or in neutral) as it removes engine braking.
-
Use a lower gear before starting downhill to maintain control.
-
Avoid braking on bends — brake early and smoothly.
-
Excessive braking can cause brake fade, reducing stopping power.
Look for ‘Low Gear’ signs and escape lanes for runaway vehicles.
Maintain a safe separation distance, as downhill stopping distances are longer.
Hills in Towns
On urban hills:
-
Keep extra space between vehicles.
-
Watch for pedestrians crossing near junctions or lights.
-
Use the parking brake when stopped.
-
Select the correct gear before moving off.
Traffic lights, crossings, and junctions are often placed on hills — be prepared for vehicles ahead to roll back or stop suddenly.
