On the road in France this summer?
To avoid long waits and traffic jams, try in particular to avoid red Saturday 28th July (travelling from north to south) and 4th/11th August, which are both ‘black days’ (circulation extrêmement difficile). August 18th is also expected to be the worst day to travel back from south to north.
Most Saturdays throughout July and August are classed ‘red’ (circulation très difficile) starting from 6th July, with the weekend of 10th – 16th Augusty being particularly busy both ways.
