How could you save fuel?
- A By extending the vehicle's service times
- B By braking as late as you can
- C By planning routes to avoid congestion
- D By selecting lower gears
Why this is the answer
You should always plan your route. This will make sure you always drive on roads that are suitable for the size and weight of your vehicle. By planning to avoid peak travel times, you can also avoid congestion. This can save you fuel, as well as reducing your journey times.
Why the other answers don't fit
- A
- By extending the vehicle's service times — Stretching service intervals leaves the engine running less efficiently, so it uses more.
- B
- By braking as late as you can — Late braking throws away the speed you burnt fuel to reach.
- D
- By selecting lower gears — A lower gear means higher revs for the same speed, which costs fuel.
