What is the procedure for a coach driver crossing international borders (e.g. from Switzerland into France or Italy) on an occasional tour?

1. Drive across the border at full speed without stopping
2. Before departure, verify the route-specific journey form or authorisation, operator and vehicle documents, insurance evidence, driver licence/qualification and tachograph records; passengers remain responsible for their own travel documents
3. Throw all documents away before the border
4. Customs documents are only required for cargo trucks, not passenger buses
