(1)Where in pursuance of section 115(1) of this Act the licensing authority revokes a heavy goods vehicle driver's licence, the authority may—
(a)order the holder to be disqualified indefinitely or for such period as the authority thinks fit for holding or obtaining such a licence; or
(b)if the licence is a full licence and it appears to the authority that, owing to the conduct or physical disability of the holder of the licence, it is expedient to require him to comply with the prescribed conditions applicable to provisional licences under this Part of this Act until he passes the prescribed test of competence to drive heavy goods vehicles of any class, order him to be disqualified for holding or obtaining a full licence until he has, since the date of the order, passed such a test.
(2)Where the holder of a heavy goods vehicle driver's licence is disqualified under subsection (1)(a) above, the licensing authority for the traffic area where he resides may, in such circumstances as may be prescribed, remove the disqualification, but so long as the disqualification continues in force a heavy goods vehicle driver's licence shall not be granted to him and any such licence obtained by him shall be of no effect.
(3)Where the holder of a full licence is disqualified under subsection (1)(b) above, a licensing authority shall not thereafter grant him a full licence to drive a heavy goods vehicle of any class unless satisfied that he has since the disqualification passed the prescribed test of competence to drive vehicles of that class, and until he passes that test any full licence obtained by him shall be of no effect.
