Snow codes and information on variable message signs 

Snow codes (white to black) indicate the stages of evolution of the snow event associated with both the intensity of snowfall and the state of the road to activate the planned prevention and management activities.
 

Codice bianco
High-impact weather alert issued
Prevista neve
Roads salting

Codice verde
Structures ready to operate before rainfalls
Prevista neve
Roads salting
Veicoli antineve
Codice giallo
Non-critical snowfall with no impact on traffic flow.
Nevischio
Non-critical snowfall on challenging sections and/or with increasing traffic
Neve
Codice rosso
Intense snowfall managed stretching the potential/possibility limit
Neve forte
Codice nero
First vehicles placed sideways on the carriageway
Blocco per neve
Vehicles placed sideways in several places or estimation of no time to solve the first blockage

Traffic regulation measures during snowfall 

In order to enable the operating vehicles to work effectively, specific measures are taken, in cooperation with the traffic police, to prevent possible traffic congestion. These measures, which make it possible to optimise traffic intensity, are:

  • CARRIAGEWAY REDUCTIONS referred to as filters
    Pannello riduzioni di carreggiata
     
  • THE TEMPORARY BAN on heavy goods vehicles

     
  • THE DYNAMIC HGV BLOCK
TEMPORARY BAN AND DYNAMIC BLOCKING OF HEAVY GOODS VEHICLES

The purpose of dynamic filtering is to prevent operating vehicles from being obstructed or slowed down by the presence of heavy vehicles, especially if they are not adequately equipped for adverse weather conditions.

The dynamic filtering protocol for HGVs over 7.5t can be ordered and immediately enforced by the licensing bodies, in agreement with the Traffic Police, in the event of a 'red' or 'yellow' code, with a tendency to intensify.

Generally, dynamic filtering is implemented using the appropriately identified lanes upstream and in the section affected by snowfall.

 

Practical driving tips in snowy conditions 

  • Adapt your driving style to the environmental conditions.
  • In the event of delays: keep to the right and give way to snow-clearing vehicles. Travel in a queue at low speed.
  • In a bad weather forecast, always leave with a full tank of fuel and relief supplies.
  • Avoid sudden movements, hard acceleration, hard braking and excessive speed.
  • Increase the distance between your car and the car in front of you.
  • It is essential to anticipate braking in order to have the necessary space to stop. Use the engine brake and the brake pedal alternately to avoid skidding and losing control of the vehicle.
  • When going uphill use a higher gear than you would normally use in the dry and when going downhill use a lower gear.
  • In the event of locking and skidding, release the brake pedal to regain grip, then brake again, progressively. When starting the vehicle on snow, accelerate gradually.
  • Before curves, reduce speed, making sure to slow down in a straight line. To handle the curve safely, the action on the steering wheel must be smooth and steady.
  • In curves, maintain a low and regular speed. If the front end no longer has directional stability, you must regain grip by reducing speed, thus taking your foot off the accelerator.
