Motorists face tougher MOT tests on their vehicles from Sunday, as an updated test introduces new categories under which a vehicle can fail or pass.

The categories include "dangerous", "major" and "minor" which determine whether a car, van or motorcycle must be taken off the road or can be driven as long as repairs are carried out.

The MOT will also be tougher on diesel emissions.

Vehicles with a diesel particulate filter will now have to pass new tests.
