Eco-driving, often called sparsam körning or miljövänlig körning in Swedish, is a built-in part of category B driver education. Transportstyrelsen's rules for the driving test say you must be able to drive in a way that is both traffic-safe and environmentally friendly. In other words, eco-driving is not an optional extra. It is part of what "good driving" means in Sweden.

The good news is that eco-driving and safe driving use the same core skill: planning ahead.

The core habits

Look far ahead

Most fuel is wasted when you accelerate towards something you will soon have to brake for. If you see a red light, a queue or a roundabout far ahead, release the accelerator early and let the car roll. You arrive at almost the same time, use less fuel and have more margin if something happens.

Use engine braking

In most modern petrol and diesel cars, fuel injection is cut when you lift off the accelerator in gear. Rolling with engine braking uses close to no fuel. In an electric or hybrid car, lifting off lets the car regenerate energy into the battery. Hard braking turns that energy into heat.

Keep a steady speed

Constant speed changes cost energy. Keep a steady pace, and on longer roads use cruise control where it is safe. Remember that air resistance grows sharply with speed, so a few km/h less on a rural road or motorway makes a noticeable difference in consumption.

Choose the right gear

In a manual car, shift up early and drive at moderate engine speeds. Avoid labouring the engine at very low revs when accelerating. In an automatic car, smooth pressure on the accelerator lets the gearbox choose economical gears.

Avoid unnecessary idling

Idling uses fuel and pollutes without moving you anywhere. Many Swedish municipalities have local rules that limit how long you may leave the engine running while parked. Switch off when you are waiting, and do not warm up the engine by idling.

Eco-driving before you start the engine

  • Tyre pressure: low pressure increases rolling resistance and fuel consumption, and makes the car handle worse. Check it regularly, especially when temperatures drop.
  • Extra weight and drag: remove roof boxes, bike racks and heavy loads you do not need.
  • Cold starts in winter: a cold engine uses more fuel and releases more emissions. An engine heater (motorvärmare) is common in Sweden for this reason.
  • Trip planning: combine errands into one trip, avoid rush hour when you can, and consider whether the short trip needs a car at all.

How eco-driving appears on the tests

On the theory test, expect questions about fuel consumption, emissions, tyre pressure, roof loads, engine braking, cold starts and how speed affects energy use. Environmentally friendly driving is part of the category B curriculum.

On the driving test, eco-driving is not a separate exercise. It shows through how you drive: planning ahead, smooth speed changes, sensible gear choice and avoiding unnecessary stops and starts. A learner who races between traffic lights and brakes hard at every junction shows weak planning, which the examiner notices from a safety point of view as well.

Typical theory test traps

  • "Driving faster gets you there sooner, so it saves fuel." False. Higher speed increases air resistance and consumption much more than the time saved.
  • Coasting in neutral. Rolling in neutral keeps the engine running on fuel and reduces control. Rolling in gear is both cheaper and safer.
  • Warming up by idling. It wastes fuel and does not warm the engine efficiently. Start driving gently instead.
  • Underestimating small things. Questions often test whether you know that tyre pressure, roof boxes and extra weight raise consumption.
  • Treating eco-driving as slow driving. The right answer is usually about planning and smooth flow, not crawling below the speed of other traffic.

Practice idea for your next drive

Pick a familiar route with traffic lights. Drive it once normally and note how often you brake hard. Drive it again, looking further ahead and releasing the accelerator earlier. If your trip computer shows consumption, compare the two. Most learners see that the calmer drive was not slower.

FAQ

Is eco-driving part of the Swedish driving test?

Yes. The driving test must show that you can drive in a traffic-safe and environmentally friendly way. It is assessed through your overall driving, not as a separate task.

What is the easiest way to save fuel when driving?

Look far ahead and release the accelerator early, so you roll in gear instead of braking. Keeping a steady, moderate speed and correct tyre pressure also help.

Do eco-driving questions appear on the Swedish theory test?

Yes. Environment and fuel-efficient driving are part of the category B curriculum, so expect questions on speed, tyres, loads, engine braking and cold starts.
