Maybe it’s just the firm i work for,but to make all the numbers match up i had to exchange my driving licence,get a new tacho card and get the Fimo card registered with the same number;It all seemed a load of tosh,but it’s what they wanted.I drove for them for years on a uk licence ,cpc,etc and then they wanted to change it.Except my haz cert,which i kept until the validity ends.
3 monts for the Prefecture in Angers to exchange my plastic card for a pink paper one.They kept my uk licence,and tacho card for return to the uk.
