Eco-safe driving
Eco-safe driving means driving smoothly and planning ahead so you use less fuel and produce fewer emissions. The same habits that save fuel, such as looking well ahead and avoiding harsh braking, also make you a safer driver.
Safety always comes first. A fuel-saving habit is never worth it if it means less control or poorer observation.
By the end of this topic you can
- You can plan ahead so you rarely need to brake hard.
- You can accelerate smoothly and change gear at sensible engine speeds.
- You can use the highest suitable gear without making the engine labour.
- You can reduce waste from idling, extra weight and poor tyre pressures.
- You can explain why coasting is not eco-safe driving.
What you need to know and understand
- Harsh acceleration and late braking waste fuel.
- Looking well ahead lets you ease off early and keep moving smoothly.
- Higher speeds use much more fuel, as well as increasing stopping distances.
- Under-inflated tyres waste fuel and reduce grip.
- Roof boxes, roof racks and extra weight increase fuel use.
- Coasting in neutral or with the clutch down reduces your control and is not good practice.
- Leaving the engine running while parked wastes fuel and adds pollution.
Plan ahead, brake less
Most fuel is wasted getting the car moving and then throwing that energy away by braking. If you spot a red light, a queue or a junction early, you can lift off the accelerator and let the car slow gently, often arriving as the traffic moves again. That saves fuel, saves brakes and gives you more time to deal with hazards.
Never creep up to a junction you cannot see into just to avoid stopping. Stopping and looking properly is always the right choice.
Smooth control habits
- Press the accelerator progressively. Smooth does not mean slow when joining faster traffic.
- Change up when the engine is comfortable at the new speed, without letting it labour.
- You do not always need every gear in order. Your instructor can show you when skipping a gear is safe.
- In a car with a gear shift indicator, use it as a guide, not a rule.
- Keep to a steady speed where you can, rather than speeding up and slowing down.
Before you even start
- Check tyre pressures regularly and keep them at the maker's recommended level.
- Remove roof boxes, bike racks and heavy items you do not need.
- Combine short trips, as a cold engine uses more fuel.
- Do not leave the engine running while you wait in a parked car.
- Use air conditioning sensibly. Demisting the windscreen for safety always comes first.
Common mistakes
- Accelerating hard away from lights, then braking hard at the next ones.
- Labouring the engine in too high a gear at low speed. Change down when needed.
- Coasting downhill in neutral to save fuel. It reduces control.
- Driving with under-inflated tyres. Check pressures monthly.
- Holding up traffic by being too slow. Make reasonable progress.
