As I indicated in the reply to which the Deputy refers, while I have no immediate plans to change our legislation in this regard, I will consider making it mandatory for drivers to advise the RSA of a change of address in the context of future road traffic legislation.
Should I decide at that point to legislate in that regard, I would of course take into account the question of return of the old licence if a replacement licence was issued. However, this may not be necessary as long as the person's updated address is captured on the National Vehicle and Driver File.
I would like to point out as well that, under EU and national law, a person may hold only one valid driving licence at a time. When a driving licence is replaced, the old licence ceases to be valid.
