Winter driving in Haute-Savoie: what the road actually asks of you
By the VANTAGE editorial team ·
Between 1 November and 31 March, the roads around Megève are governed by the Loi Montagne. But regulation is the floor, not the standard — the mountain rewards preparation far beyond the legal minimum.
What the law requires
In the listed communes of Haute-Savoie, vehicles must carry either winter or all-season tyres marked 3PMSF, or have snow chains or socks on board for two drive wheels. Megève, Combloux, Saint-Gervais and Praz-sur-Arly are all concerned.
Winter tyres beat all-seasons above 1000 m
All-season tyres satisfy the law and suit the valley. Above 1000 metres, with repeated freeze-thaw and shaded hairpins, a true winter compound changes braking distances materially — which matters most on the descent, not the climb.
Where the road catches people out
The shaded curves between Sallanches and Demi-Quartier, the crest at Mont d'Arbois after dusk, and chalet driveways at first light. Black ice forms where the sun never reaches, long after the main roads look clear.
Habits that matter
Leave earlier than the map suggests, brake before the corner rather than in it, keep the fuel or charge above half in cold weather, and treat a snowfall departure as a different journey entirely.
Frequently asked
- Are snow chains mandatory in Megève?
- Either 3PMSF-marked tyres or chains/socks on board are mandatory from 1 November to 31 March in the concerned communes, which include Megève.
- Can I drive a rear-wheel-drive car in Megève?
- Yes, with proper winter tyres and care on the steeper approaches — though four-wheel drive with winter tyres remains far more comfortable during snowfall.
- Who is responsible for checking equipment?
- The driver. On chauffeur-driven journeys, that responsibility, along with the chains and their fitting, sits with us.
