Hi everyone. For anyone who has driven to Italy from

We drove via the Frejus tunnel, not the Mont Blanc, but I would guess its the same - precisely nothing! Since there is no border (both Schengen) there are no controls. 

Government website says you need  a Passenger Locator Form and a Covid Test Certificate (less than 48 hours old).

Hi Alan - of course you are right, and we had all the necessary paperwork; the point of my post was simply that in fact no-one asked us to show anything (and I know at least 2 others who had the same experience). At the time we went we were also supposed to register with the local USL but despite strenuous efforts it proved impossible. Its different of course when you fly, but the only controls we experienced were at Folkestone before the train.
