Control on Hills & Bends

Gravity works against you going downhill and tests your positioning on every bend. Learn to let the engine hold your speed on a descent, slow down before a bend rather than during it, and pull away on a hill start without rolling back.

Flat, straight roads rarely expose bad habits. Hills and bends do: ride the brakes downhill and they can fade just when you need them; brake mid-bend and the car's balance shifts right when grip matters most. Both problems have the same fix — sort your speed out before you're committed.

💡

The big idea: Going downhill, select a lower gear and let engine braking do the work instead of riding the brakes. Approaching a bend, slow to the right speed before you turn in, not while you're in it. And on a hill start, control the handbrake, clutch and accelerator together so the car doesn't roll back.

Road Surfaces, Skids & Coasting

Steep hills are signposted before you feel the gradient

Before a long descent or climb, a triangular warning sign showing the gradient gives you time to prepare — choose your gear, check your following distance, and decide your speed while the road is still flat enough to do it calmly.

Steep-hill signs show the direction of the gradient and often state it as a ratio or percentage — your cue to select your gear and speed early.

Downhill: let the engine hold you back

On a long or steep descent, select a lower gear before you start down, not halfway through it. A lower gear increases engine braking — the engine's own resistance to turning over — which helps hold your speed steady without needing constant, heavy use of the brake pedal.

Riding the brakes continuously on a long descent builds up heat faster than they can shed it, and hot brakes lose stopping power just when a steep hill demands the most from them — a problem often called brake fade. Using a lower gear for most of the descent, and applying the brakes in shorter, firmer presses rather than one long drag, keeps them working at full effect.

🔑 Brake fade: why continuous braking backfires

Brakes work by converting speed into heat through friction. Ride them continuously down a long hill and that heat has nowhere to go, so the brakes become progressively less effective — the opposite of what you want partway down a steep descent. Engine braking in a lower gear does most of the holding-back for you, leaving the brakes fresh for when you actually need them.

Bends: slow down before you turn in

The right moment to reduce speed for a bend is before you reach it, while the car is still travelling in a straight line and the tyres have their full grip available for braking. Braking while you're already turning asks the tyres to do two jobs — slow the car down and change its direction — at the same time, which uses up grip faster and can unsettle the car exactly when it's leaning into the corner.

Judge your speed on what you can actually see: a bend that curves away out of sight, a wet or leaf-covered surface, or an approaching vehicle taking up part of your lane all call for slowing down more before you commit to the turn.

✨ Slow in, then look through the bend

Get your speed sorted before the bend, then look as far around the curve as you can see — your steering tends to follow where your eyes are looking. If you find yourself needing to brake once you're already turning, that's the signal you entered a touch too fast; ease off and slow down earlier next time.

Hill starts: handbrake, clutch, and a smooth handover

Pulling away on an uphill gradient without rolling back means coordinating three things together: bring the clutch up to the point where you feel the engine start to take the car's weight (the biting point), add a little gas, and only then release the handbrake as the car begins to move forward. Releasing the handbrake too early, before the engine and clutch are ready to hold the car, is what causes a roll-back — a particular hazard with another vehicle stopped close behind you.

Many modern cars offer a hill-hold or auto-hold function that keeps the brakes applied for a moment after you release the pedal, giving you the same result with less coordination required — useful to know how to use if your car has it, but the handbrake method works in any car.

Check your understanding

1. What is the recommended way to control your speed on a long, steep descent?

A lower gear increases engine braking, holding your speed steady without relying on continuous heavy braking, which can overheat the brakes and cause brake fade.

2. When is the best time to slow down for a bend?

Slowing before the bend, while the car is still straight, means the tyres have their full grip available for cornering rather than sharing it with hard braking.

3. What mainly causes a car to roll back during a hill start?

If the handbrake comes off before the clutch has reached the biting point with enough gas to hold the car, there's nothing yet keeping it from rolling back.

4. What does continuously riding the brakes on a long downhill stretch risk?

Continuous heavy braking generates heat faster than the brakes can shed it, reducing their stopping power — brake fade — right when a steep hill needs it most.

✅ Key takeaways

Steep-hill warning signs give you time to choose your gear and speed before the gradient starts.
Downhill, use a lower gear for engine braking instead of riding the brakes, which can overheat and fade.
Slow down before a bend, while the car is still straight, rather than braking once you're already turning.
On a hill start, bring the clutch to the biting point with a little gas before releasing the handbrake, to avoid rolling back.

Frequently asked questions

Why should you use a lower gear going downhill instead of just braking?

A lower gear increases engine braking, which helps hold your speed steady without relying on continuous heavy brake use — riding the brakes on a long descent can overheat them and cause brake fade, reducing their stopping power.

When should you slow down for a bend?

Before you reach it, while the car is still travelling in a straight line. Braking while already turning shares the tyres' available grip between slowing down and cornering, which can unsettle the car.

How do you stop a car rolling back on a hill start?

Bring the clutch up to the biting point and add a little gas before releasing the handbrake, so the engine is ready to hold the car's weight the moment the handbrake comes off.
