Single or carnet tickets must be stamped at the stamping machine getting on board and must be kept intact and readable for all your journey long and shown if required.
Please, be advised that in case the stamping machine is not working, it is mandatory to inform the bus driver and validate your ticket on your own, by writing on it date and time you are getting on the bus. This rule is valid both for urban or suburban ticket.
Single and carnet paper ticket not stamped has no expiry date and can be used as long as they remain intact and readable. It is not transferable.
