Regulation 13 Issue of a duplicate licence or disc and prohibition on unauthorised alteration of a disc
If a licence or disc has been lost or destroyed, the holder shall forthwith notify the traffic commissioner who granted the licence or disc so that he may provide a duplicate, marked as such.
If a licence or disc has been notified as lost or destroyed in accordance with paragraph (1) and is subsequently recovered by the holder, then the holder shall use the duplicate licence or disc and return the original to the traffic commissioner.
At no time shall any person except the traffic commissioner, or a person authorised to do so on his behalf, write on or otherwise alter a disc, but in the event that a disc becomes illegible by ordinary wear and tear the holder shall forthwith return the illegible disc so that the traffic commissioner may provide a duplicate, marked as such.
