Environmental Protection and Eco-Friendly Driving
What this domain tests
Eco-driving questions check whether you can reduce fuel use and emissions without compromising safety. The exam rewards smooth, planned driving and basic maintenance knowledge.
Core techniques
- Accelerate and brake smoothly; harsh inputs can raise fuel use sharply.
- Aim for the economy band of roughly 60–80 km/h, where most cars are most efficient.
- Anticipate lights and traffic so you coast or engine-brake instead of braking late.
- Avoid unnecessary idling; switch off the engine during long waits.
- Remove roof racks and heavy loads, and keep tyre pressures correct.
- Use air conditioning sparingly and use fresh-air ventilation at low speeds.
Vehicle and emissions
Diesel vehicles with filters need proper regeneration; ignoring the DPF warning can lead to costly damage. SCR systems use urea solution, and running out limits performance. Electric and hydrogen vehicles reduce tailpipe emissions but still reward smooth driving for range.
Worked example
You are waiting 10 minutes for a passenger. Idling burns fuel and emits pollutants; restarting uses only a small amount. Switching off is the correct eco-driving choice, provided you are parked legally and safely.
Traps that cost marks
Believing idling saves fuel, assuming lower speed is always greener, or thinking eco-driving is only about the car's technology. Tyre pressure and driving style often matter more.
