Validation of your ticket is mandatory throughout the Île-de-France Mobilités network.
- Adopting the validation reflex means helping to improve the transport offer by sharing your travel habits.
- It allows transport operators to know the traffic on bus lines and to know the needs of passenger customers.
- In the event of an inspection, the failure to validate is punished by a fine of €35. Even if, you have it in your bag or wallet!
