As a result of the outbreak of the Covid pandemic there was a suspension and interruption of notification period between 23 February 2020 and 15 May 2020 meaning that the 360-day notification period is extended by an additional 83 days.
The Italian authorities have 360 days from the traffic violation date and the identification of the owner of the vehicle to notify foreign drivers that a fine is payable.
Note that in case of rental vehicles, the car rental company (owner of the vehicle) is initially contacted by the Police. They inform the Police of the contact details of the person in charge of the vehicle at the time of the offence. It is only when the Police receives the offending driver’s data from the car rental company that the 360 day period starts to run.
