mot testing does not always include construction of use regulations.
i.e. a car can pass an mot with a "bad boy" bonnet partially covering the headlights providing that it still allows enough light through for a beam test etc. but construstion of use regulations supposedly say that your not allowed to cover your headlights with your bonnet at all unless the car was originally constructed that way and the headlight it shaped to suite. i thought it very stange aswell, just do a side exit and let us know if ya get caught! lol
