Cultural Tip
In France, most public transport tickets must be validated by inserting them into a small green or orange machine (borne) before you board. Forgetting to do so can result in a fine if a ticket inspector checks your ticket. In some cities, like Paris, the validation is optional for certain passes, so it’s always good to ask the staff or look for signage.
