Always have your punched/stamped ticket or season ticket with you on board buses and trams. You will be required to produce it when ticket are inspected. If you benefit from reductions or free travel, you may be required to produce proof that these privileges have been granted to you.
If you travel without a ticket, you run the risk of having to pay a fine of between € 28* (immidiate payment on board the vehicle) and € 123 (after a 5-day deadline)
If payment has not been made within 2 months, the file will be fowarded to the Police Court for a ruling.
