Where can a bus or coach drive in France?

Buses and coaches are held to their own Crit'Air floor, and in at least one city it is stricter than the one for cars.

7 of the 11 French cities that record a rule for a bus or coach set a Crit'Air floor; 4 record the class but require no sticker.

Rules in force on 13 August 2026, read from each authority's own published zone rather than applied from the car table.
