Driving in France: licence, roads and tolls

Tolls at barriers on the autoroutes, a Crit'Air sticker for the cities, and priorite a droite where nothing says otherwise.

• Tolls are paid on exit by card or cash; the orange lanes marked with a "t" are for transponder holders only and blocking one is a fuss you do not want.
• A Crit'Air sticker is required in a growing list of low-emission zones - Paris, Lyon, Grenoble, Strasbourg and others. It is ordered online from the government site and takes days to arrive by post, so it is a before-you-go job.
• The alcohol limit is 0.5 g/l, and 0.2 g/l for drivers in their first three years.
• The rural limit is 80 km/h on undivided roads, except where a department restored 90 - the signs are the authority, and the cameras follow the signs.
• Priorite a droite still exists on unmarked junctions in villages, which is the one rule that catches British and American drivers.
