AtB has a dialogue with the school and the municipality ahead of ticket inspections on school lines. The inspection can take place at the school upon boarding or during the trip.
- Inspections at primary schools are carried out in civilian clothes.
- The students show their travel certificate to the inspector.
- If the student do not have a valid travel certificate, they will be asked for their name and personal details so that the inspector can check whether the student is entitled to free school transport.
