Section 78: Prohibition on holding or obtaining Great Britain and Northern Ireland licences
137.Subsection (2) prevents a Northern Ireland licence holder who obtains a Great Britain licence from continuing to be able to drive in Great Britain by virtue of the Northern Ireland licence. It provides that, on surrender of the Northern Ireland licence when a Great Britain licence is granted, the authorisation to drive a vehicle in Great Britain by virtue of the Northern Ireland licence ceases, and that the Secretary of State must send the Northern Ireland licence and its counterpart back to the Northern Ireland authorities.
138.Subsection (3) is in respect of reciprocal provisions intended in Northern Ireland law. It requires the Secretary of State, where he is satisfied that a Northern Ireland licence has been granted to the holder of a Great Britain licence and he has received the Great Britain licence, to serve written notice on the person concerned that the Great Britain licence is revoked.
139.Subsection (4) provides, in order to prevent duplication of licences, that a person holding a Northern Ireland licence to drive a particular class or classes of vehicle is disqualified from holding or obtaining a Great Britain licence to drive a motor vehicle of that class or classes, if he does not surrender the Northern Ireland licence to the Secretary of State and remains authorised to drive in Great Britain as a holder of that licence.
