What can you do to reduce environmental damage caused by your vehicle?
- A Avoid using the cruise control
- B Use the air conditioning whenever you drive
- C Use the gears to slow the vehicle
- D Avoid making a lot of short journeys
Why this is the answer
Avoid using your car for short journeys. On a short journey, the engine is unlikely to warm up fully and will therefore be running less efficiently. This will result in the car using more fuel and emitting higher levels of harmful emissions.
Why the other answers don't fit
- A
- Avoid using the cruise control — Cruise control usually helps efficiency on a steady road.
- B
- Use the air conditioning whenever you drive — Air conditioning costs fuel. Using it always is the wrong way round.
- C
- Use the gears to slow the vehicle — Good technique, but not what cuts a car's emissions overall.
