(a)absolutely, or
(b)for one or more specified purposes, or
(c)except for one or more specified purposes.
(2) If on any inspection of a vehicle under any of the enactments mentioned in paragraph (1) it appears to an authorised constable that owing to any defects in the vehicle driving it (or driving it for any particular purpose or purposes or for any except one or more particular purposes) would involve a danger of injury to any person, he may prohibit the driving of the vehicle on a road—
(a)absolutely, or
(b)for one or more specified purposes, or
(c)except for one or more specified purposes.
(3) A prohibition under this Article shall come into force as soon as the notice under paragraph (6) has been given if—

(b)in the opinion of the vehicle examiner imposing it the defects in the vehicle in question are such that driving it, or driving it for any purpose within the prohibition, would involve a danger of injury to any person.
(4) Except where paragraph (3) applies, a prohibition under this Article shall (unless previously removed under Article 81) come into force at such time not later than 10 days from the date of the inspection as seems appropriate to the vehicle examiner imposing the prohibition, having regard to all the circumstances.
