Why do MOT tests include a strict exhaust emission test?*

A To help protect the environment against pollution
Emission tests are carried out to ensure your vehicle's engine is operating efficiently. This ensures the pollution produced by the engine is kept to a minimum. If your vehicle is not serviced regularly, it may fail the annual MOT test.
B To recover the cost of expensive garage equipment
C To discover which fuel supplier is used the most
D To make sure diesel and petrol engines emit the same fumes
