Which document do you have to carry with you for a bus in cross-border traffic within the EU states?

In cross-border traffic within EU states, it is essential for bus operators to carry proper documentation to ensure compliance with regulations and to ease the smooth operation of services. The correct combination of documents includes:

1. A certified copy of the valid licence for commercial cross-border passenger traffic with coaches and buses - This document verifies that the operator is authorized to conduct cross-border transport and is critical for legal operation across borders.

2. An approved timetable - This ensures that the bus operators can provide evidence of planned schedules, which is important for passenger reliability and transparency.

3. A valid description of the location - While less critical than the first two, having a clear location description helps in navigation and identification of routes.

Carrying all these documents not only complies with German traffic laws but also helps in avoiding penalties and ensures safety and legitimacy in operations.
