  1. What is the most fuel-efficient way to drive?

    Answer: Use smooth acceleration, read the road ahead, and maintain a steady speed

    Smooth, progressive acceleration, anticipating the road ahead, and avoiding unnecessary braking are the keys to fuel-efficient driving. Planning ahead reduces the need for sudden speed changes.

  2. How does driving at higher speeds affect fuel consumption?

    Answer: Fuel consumption increases significantly — driving at 70 mph uses up to 30% more fuel than at 50 mph

    Fuel consumption increases rapidly at higher speeds due to greater air resistance. Driving at 70 mph can use up to 30% more fuel than driving at 50 mph.

  3. What is the purpose of a catalytic converter?

    Answer: To convert harmful exhaust gases into less harmful substances

    A catalytic converter converts toxic gases such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful carbon dioxide, water vapour, and nitrogen.

  4. Why should you avoid unnecessary engine idling?

    Answer: It wastes fuel, increases emissions, and is illegal in some areas with a fixed penalty notice

    Engine idling wastes fuel, produces unnecessary emissions, and contributes to poor air quality. Under the Road Traffic (Vehicle Emissions) Regulations, local authorities can issue fixed penalties for unnecessary idling.

  5. What is the benefit of keeping your tyres at the correct pressure for fuel economy?

    Answer: Correctly inflated tyres reduce rolling resistance, improving fuel efficiency by up to 2%

    Under-inflated tyres increase rolling resistance, meaning the engine works harder and uses more fuel. Keeping tyres at the correct pressure can improve fuel efficiency by up to 2% and extends tyre life.

  6. What is a ULEZ (Ultra Low Emission Zone)?

    Answer: An area where vehicles must meet minimum emission standards or pay a daily charge

    A ULEZ is an area where vehicles must meet minimum emission standards (typically Euro 4 for petrol, Euro 6 for diesel) or their drivers must pay a daily charge. London has the largest ULEZ in the UK.
