driving licence

[Fred]

Hello , help needed please.
Does anyone know how you go about doing a change of address on a french driving licence.  We went a bit too fast through the speed trap at Montmorillon today and I realized that it is probably a hanging offence not to have told the relevant authority of our change of address in September.  Any ideas gratefully received.

My thread may help it's about changing from UK to French but may have some helpful info.

The Lady in the Montmorillon sous-préfecture is very helpful.
