Bison futé predicts very difficult traffic near the Alps for this cross-country weekend. It's Saturday that it's expected to be the busiest, with congestion in Auvergne-Rhône-Alpes to access the ski resorts.
To avoid hassle on the road, the best thing will be to get behind the wheel on Sunday, classified as green for both departures and returns, throughout the country. It should be less busy than we might have feared with this second weekend of SNCF strike - this time by the switchers - which will ultimately have little impact on train traffic.
