Every year, Autostrade per l'Italia and the Italian Traffic Police jointly draw up and implement a complex snow emergency management plan to ensure suitable road conditions on highway stretches as well as motorist safety. The aim is that of:
- encoding the various snow emergency phases, indicating operational coordination and user information measures for each phase.
- taking appropriate action, including the temporary restriction of heavy vehicles, to ensure the best possible conditions and winter service vehicle performance.
In its Snow Plan, Autostrade per l'Italia envisages the involvement and the activation of:
- 9 radio rooms, a National Multimedia Centre and a National Traffic and Emergency Coordination Centre to monitor events and coordinate staff and winter service vehicles;
- 168 snow depots for the service vehicles and/or chloride deposits;
- 1024 snow ploughs;
- 183 salt gritters;
- 236 combination vehicles for spreading chlorides and clearing the snow;
- 149 calcium chlorides sprinklers;
- 156 mechanical shovels for loading the salt;
- 185 vehicles for clearing or removing snow from service areas, parking lots and toll booth areas;
- 26 Unimog vehicles equipped with ploughshares and rotors to remove snow build-ups in emergency lanes
- 61 heavy rescue vehicles to assist vehicles with gross vehicle weight of more than 7.5;
- 9 strategic sodium chloride deposits.
The Traffic Police also contributes to this with:
- 10 operational highway centres;
- 310 motor vehicles;
- 280 patrols per day;
- 1726 operators.
Autostrade per l'Italia and the Traffic Police keep the Prefecture and the competent local authorities continuously updated on all critical issues at every stage of the snow event. This allows the local authorities to take any necessary steps to restrict traffic throughout the area adjacent to the highway or to provide the necessary assistance in the event of blocked traffic.
Traffic and weather information
Information on weather and traffic conditions and, where applicable, and information on alternative routes, is passed on to motorists through the following channels:
- "My Way" news broadcast on the Sky Meteo24 television channel
- specific messages on variable message panels alerting motorists of road and weather conditions on the highway stretches affected by snow, of the steps taken by Autostrade per l'Italia and the Traffic Police to manage the snow event, and transmitting any type of information;
- RTL 102.5 and Isoradio 103.3 radio stations;
- Onda Verde news broadcast by CCISS Viaggiare Informati on Radio 1, Radio 2 and Radio 3;
- Traffic Call Centre on 840.04.21.21;

Winter Equipments (snow tyres or chains)
Legal requirements and no overtaking for trucks - Dates and Motorways
Autostrade per l'Italia asks motorists and road hauliers to ensure they are adequately equipped for the next winter season.
From November, motorists travelling on highway stretches at greater risk of snow or ice will be required to fit snow tyres or have snow chains on-board, in accordance with orders issued by Autostrade per l'Italia or by the authorities who own the highways (e.g. the State, regions, provinces or municipalities)
Motorists are alerted to the requirement to fit snow tyres or carry chains on-board by road signs that are placed along the highway stretches and entrance toll booths affected by the orders.
It should be borne in mind that suitable equipment translates as safety during bad weather, especially heavy snow.
Motorists not suitably equipped will incur financial penalties of between €80 and a maximum of €318 (art. 6, paragraph 14 of the Italian Highway Code).
A list of the highway stretches in which winter tyres or on-board chains are required between 15 November and 15 April¹, in accordance with orders issued by Autostrade per l'Italia, is set out below.
