Update 2021-05-26: According to current information from the Federal Foreign Office on Wednesday (26 May), Italian hygiene regulations have changed: From now on, the occupants of vehicles no longer have to come from the same household. Accordingly, up to 5 persons from the same household (without mask obligation) are allowed in a vehicle, but only a maximum of 3 persons from several households (with mask obligation and 1 metre distance). The mask requirement does not apply if the car is equipped with a separating device (e.g. plexiglas) between the front and rear rows of the vehicle (e.g. taxis), according to the Federal Foreign Office.
