| Period | Rule |
|---|---|
| 15 Oct – 14 Nov | Changeover window: winter tyres allowed |
| 15 Nov – 15 Apr | Obligation active on signed roads: M+S tyres or chains on board |
| 16 Apr – 15 May | Changeover window: remove lower-speed-code winters |
| 16 May – 14 Oct | Lower-speed-code winter tyres prohibited |
«Chains on board» satisfies the rule only if they fit your tyres and you mount them when conditions/signs demand. All-season tyres with M+S (better: the 3PMSF snowflake) satisfy the winter obligation and dodge the summer trap if their speed code matches the document.
Non-compliance on signed roads: fines from ~€42 in town to ~€87–345 outside, plus the possible order to stop until compliant. In actual snow, non-equipped vehicles blocking traffic collect both the fine and the tow. The summer speed-code violation runs into the hundreds with a possible revision order for the tyre mismatch. Mountain reality: carabinieri checkpoints at pass entrances on snow days are routine.
Renting in Italy in winter: confirm the car has winter/all-season tyres — most northern fleets do, but it's a contract line worth reading, and driving to ski areas without them can void assistance. Driving your own car from abroad: your home equipment must still satisfy the Italian signs on the roads you use. Alpine tunnel crossings pair naturally with this topic — see the tolls guide for the Mont Blanc/Fréjus context; and yes, winter-equipment signs are in the ministerial quizzes.
