Change up a gear when the engine starts to sound busy and the car has gained enough speed for the next gear, and change down when you slow down and the engine starts to labour or you need more power, such as for a hill or overtaking. As a rough guide, many cars go into second at about 10 mph, third at 20, fourth at 30, fifth at 40 and sixth around 50, but every car is different.
Here's how to choose the right gear, change smoothly and avoid the classic beginner mistakes.
A rough gear and speed guide
This table is a starting point for a typical petrol or diesel car on level ground. Your car, its load and the road will change it.
| Gear | Typical use | Rough speed range |
|---|---|---|
| 1st | Moving off, very slow manoeuvres | 0–10 mph |
| 2nd | Slow traffic, tight turns, junctions | 10–20 mph |
| 3rd | Town roads, 20–30 mph zones, some bends | 20–30 mph |
| 4th | 30–40 mph roads | 30–40 mph |
| 5th | Faster roads | 40 mph and above |
| 6th (if fitted) | Cruising on faster roads | 50 mph and above |
Many modern cars show a gear-shift indicator on the dashboard suggesting when to change up or down, which is helpful while you're learning.
How to know when to change gear by sound and feel
- Change up when the engine sounds like it's working hard and getting louder, and the car is no longer gaining speed easily.
- Change down when the engine sounds strained, the car shudders or "labours", or it won't accelerate.
- Diesel engines usually want to change up at lower revs than petrol engines.
How to change gear smoothly
- Ease off the accelerator.
- Press the clutch fully down.
- Move the gear lever to the next gear with a light, open-palm touch, guiding rather than forcing it.
- Raise the clutch smoothly, while gently pressing the accelerator.
- Hands back on the wheel straight away.
Keep your eyes on the road. To learn the gear positions, practise with the engine off and the parking brake on.
When to change down
- Slowing for a junction or bend: brake first to the right speed, then select a gear that suits that speed.
- Going up a hill: change down before the engine labours.
- Overtaking or joining faster traffic: a lower gear gives you more acceleration.
- Going down a steep hill: a lower gear helps control speed with engine braking, so you don't overuse the brakes.
Brakes to slow, gears to go
A useful rule of thumb: use the brakes to slow down and the gears to go. You don't need to change down through every gear as you slow. Brake to the speed you want, then pick the right gear. This is called block changing: for example, fifth to third, or fourth to second.
Common gear changing mistakes
- Looking down at the gear lever instead of the road.
- Coasting with the clutch down or in neutral for long periods. You have less control, especially downhill.
- Riding the clutch (resting your foot on it).
- Staying in a low gear too long, which wastes fuel and makes the engine noisy.
- Being in too high a gear at low speed, causing the engine to labour or stall. See how to stop stalling.
- Changing gear mid-corner when you should have chosen the gear before the bend.
Gears and fuel economy
Changing up in good time and driving smoothly saves fuel. Avoid harsh acceleration and anticipate the road ahead so you can ease off early rather than brake hard. Good anticipation is also the heart of defensive driving.
Summary
There's no single correct speed for each gear, but the rough guide above plus listening to the engine will get you most of the way. Change up when the engine sounds busy, change down when it labours or you need power, block change when it makes sense, and keep your eyes on the road.

Frequently asked questions
What speed should I change gear at?
As a rough guide, many cars change from first to second at around 10 mph, second to third at 20, third to fourth at 30, fourth to fifth at 40 and fifth to sixth around 50. It varies by car, load and gradient, so listen to the engine and use the gear-shift indicator if your car has one.
Can I skip gears?
Yes. Block changing, such as going from fifth to third or fourth to second, is fine and often smoother, as long as your speed suits the gear you choose.
Should I look at the gear stick when changing gear?
No. Keep your eyes on the road. Practise with the engine off until you can find each gear by feel.
Do I need to change down before stopping?
Not necessarily. Many instructors teach braking to slow down and then pressing the clutch just before you stop, rather than working down through every gear.
