Changing UK for French tacho card

I’ve been told that while exchanging my UK tacho card for a French one, I cannot drive. I need to send the card off then wait two to three weeks for the new one to come thru and in the interim I cannot drive. Anyone know if that’s right or not? Thanks.

I have just sent off for French card, they didn’t ask for my UK one which I still have and is in date.

Hiya, Thanks a lot for your reply. Amazingly I got the card back in a week. The quickest I’ve ever had any admin processed here!
