Environmental Awareness and Fuel-Efficient Driving
Fuel-efficient driving reduces cost and emissions at the same time. Smooth driving is the core principle: accelerate gently, maintain a steady speed, and anticipate stops so you can ease off the accelerator rather than brake hard. Use the highest safe gear for the speed; labouring in a low gear wastes fuel. Avoid unnecessary idling - switch off the engine if stationary for more than a short period. Remove roof racks and excess weight when not needed, and keep tyres correctly inflated, because under-inflation increases rolling resistance.
Plan journeys to avoid peak congestion and combine errands into one trip; a cold engine uses more fuel, so short repeated trips are inefficient. Use air conditioning sparingly at low speeds and prefer ventilation; at higher speeds, open windows increase drag. Regular servicing - clean air filters, correct oil, properly tuned engine - keeps consumption low. Avoid aggressive acceleration and late braking, which can raise fuel use substantially.
Question traps: candidates assume a lower gear always saves fuel, or that idling is harmless. Another trap is believing that fuel additives replace good driving habits. Environmental awareness also covers avoiding unnecessary horn use and not dumping oil or batteries, which pollute soil and water.
Worked example: A question asks how to reduce fuel use in city traffic. Answer: drive smoothly, avoid harsh acceleration and braking, use the correct gear, and switch off the engine during long waits.
