Leaving the car window 10 centimetres open when parking can cost €42 in Italy. Authorities consider it a provocation to theft and a security breach for the vehicle.
An infraction that many Italian drivers are unaware of is already leading to the first fines. Parking the car with the windows slightly down, a common practice on hot days to prevent the interior from becoming an oven, can result in at least €42 in fines.
The Italian police have begun enforcing this penalty based on Article 158 of the Highway Code, which requires the driver to take all necessary measures to ensure the security of the parked vehicle. Leaving a gap of about 10 centimetres in the window is interpreted as a provocation to theft, as it facilitates access to third parties.
This measure is not new, but it has gained prominence in recent weeks following several complaints from drivers caught off guard by the fine. Italian authorities believe that the owner is not properly securing the vehicle against potential unauthorised use, and therefore impose the penalty immediately.
The fine amounts to a minimum of €42, although it can increase if other circumstances apply, such as parking in a high-risk area or if the vehicle contains visible valuable items. In some cases, the penalty has reached €100.
This regulation contrasts with legislation in other European countries. In Spain, for example, there is no specific penalty for leaving the window open, although officers can issue fines if they believe the vehicle is not properly secured and poses a security risk. In France, this practice is also not classified as a standalone infraction.
The Italian police remind that the obligation to secure a parked car includes closing doors, windows, sunroofs, and the boot. Failing to do so is considered negligence that can facilitate theft, and the driver assumes responsibility.
Leaving the window down 10 centimetres is interpreted as a provocation to theft, according to Italian authorities.
Drivers travelling to Italy should keep this rule in mind to avoid surprises. The recommendation is to fully close the windows when parking, even if it is hot. Alternatively, one can use sunshades or park in shaded areas to mitigate the interior temperature.
The penalty applies to both tourists and residents, and does not accept claims based on the weather. Authorities are firm in their interpretation: vehicle security takes precedence over thermal comfort.
For those who have already received the fine, the voluntary payment period is 5 days, with a 30% discount on the amount. After this period, the penalty increases and may lead to the loss of points on the driving licence if similar infractions accumulate.
This regulation adds to other peculiarities of the Italian highway code, such as the obligation to carry a reflective vest in the car or the use of snow chains during certain periods. Knowing them can save Spanish drivers more than one unpleasant surprise when crossing the border.
