immatriculation

It doesn't matter what answers you get here, if your insurers say that you will not be insured you cannot drive - so ask your insurers.

We have been driving our new car for a week, with the assurance from our insurers that it's OK. I am filling in the pink form today.

Check with insurer -- In our case insurer gave us a photostated form they signed that confirmed ok to drive. Being the cynic I am -- I wouldn't trust anyone (even the insurer -- unless I have a piece of paper in my hand) -- very easy to say something over the phone or face to face -- then deny it if something happens
