Environmental Awareness and Fuel-Efficient Driving
Why eco-driving is examined
Fuel-efficient driving reduces emissions, saves money and improves safety, because the techniques that save fuel also smooth out speed changes. The exam tests whether you understand how driving style, vehicle condition and planning affect consumption and pollution.
The main techniques
Start gently and change up early; drive in the highest practical gear at low revs. Anticipate traffic so you can lift off the accelerator instead of braking hard. Maintain a steady speed and use cruise control where appropriate. Switch off the engine when stationary for more than a short period, unless in traffic where restarting is unsafe. Remove roof racks and unnecessary loads, and keep tyres correctly inflated, because under-inflation increases rolling resistance. Use air conditioning sparingly, as it raises consumption noticeably.
Planning and pollution
Combine errands into one trip, car-share, and consider walking, cycling or public transport for short journeys, since cold engines pollute disproportionately. Avoid unnecessary idling. Keep the vehicle serviced: a poorly tuned engine burns more fuel and emits more pollutants. Never dump oil, batteries or tyres in the environment; use designated collection points.
Noise and the environment
Aggressive acceleration and unnecessary horn use create noise pollution, which is also regulated. Driving style affects both air and noise pollution.
Worked example
Two drivers cover the same 20 km. One accelerates hard between lights and brakes late; the other anticipates and coasts. The smooth driver uses noticeably less fuel. The rule of thumb: every harsh acceleration and late braking event wastes energy that was already paid for at the pump.
Traps to watch
Questions often suggest that idling saves fuel on short stops; it does not, and modern engines restart cheaply. Also remember that a warm engine is more efficient, so short cold trips are the least efficient of all.
