How long are permits and discs valid?
Indefinitely. However, permits may be taken away or any conditions attached to them may be varied at any time by the body that issued it or by the Traffic Commissioner – although before doing so the Traffic Commissioner would have to tell the issuing body what he proposed to do. Permits cease to be valid if the body which issued them stopped operating or had their right to issue permits revoked. If a permit is revoked or no longer valid it must be returned to the body which issued it or, in the case of a body which is no longer authorised to issue permits, to the Traffic Commissioner.
