When may red diesel be used?
- A For operators to reduce running costs
- B For authorised purposes only
- C For garages to test-drive repaired vehicles
- D For environmental purposes
Why this is the answer
Red diesel is subject to less excise duty than standard diesel, so it's considerably cheaper. It may only be used for authorised purposes. Any driver whose vehicle is found to be using this fuel illegally faces penalties.
Why the other answers don't fit
- A
- For operators to reduce running costs — Cutting costs is exactly the misuse the rebate exists to prevent.
- C
- For garages to test-drive repaired vehicles — A test drive on a public road is ordinary road use and needs ordinary fuel.
- D
- For environmental purposes — Red diesel is not cleaner. The colour marks the duty paid, not the emissions.
