Winter in Italy: chains, Alpine passes and the bora

Italian winter is two countries. On the plains it is fog and rain; in the mountains and on the eastern border it is genuinely serious weather, and the equipment rules exist because of it.

Winter equipment

Between mid-November and mid-April, winter tyres or chains on board are required on many Italian roads, with the exact rule set locally and signposted. On Alpine roads and the passes it is enforced, and the sanction is not the main risk — a vehicle without grip on a gradient is.

Damage from sliding on a gradient concentrates in the underbody, the suspension and the steering geometry rather than the panels. It is routinely underestimated at the roadside precisely because the bodywork can look almost untouched.

The bora on the eastern border

The A4 between Venice and Trieste has a hazard that exists almost nowhere else: a katabatic wind that reaches speeds capable of overturning high-sided vehicles. Caravans, campers, box vans and cars with roof loads are at risk, and the exposed viaducts near Trieste are where it happens.

If a wind warning or a restriction for high-sided vehicles is in force, treat it as a hard limit. Where wind caused the damage, record the conditions at the scene — the meteorological facts are part of the evidence and they are unavailable later.

Mountains, tunnels and short days

Passes and mountain tunnels combine ice at the entrance, dry road inside and ice again at the exit. Add ski traffic at weekends and loaded roof boxes, and the winter accident profile writes itself.

One practical note for anyone travelling to ski: a roof box torn off or a bike rack damaged in an accident is part of the loss and needs documenting in place. It is also the item most often cleared away before anyone photographs it.

Frequently asked questions

I had an accident without winter tyres. Does that end my claim?

It is a question of liability and of your policy terms, not of the technical assessment. The damage is documented on its own merits; how the equipment question affects the settlement is a legal matter, and there we recommend a lawyer specialising in traffic law.

The wind pushed my caravan into the barrier.

Photograph the scene, the barrier and the vehicle, and record the time and any warning in force. Wind damage without documentation of the conditions is very hard to characterise afterwards.

The car slid and hit a kerb. Nothing looks damaged.

Have the underbody and the steering geometry checked before a long drive home. Kerb impacts on ice concentrate exactly there, and the symptoms appear as uneven tyre wear a month later.
