What must you consider when driving your bus through narrow passageways?

The combination of answers you selected is correct because both considerations are crucial for safely navigating narrow passageways with a bus.

1. The outside rear-view mirrors project beyond the width of the vehicle as documented. This means that when maneuvering through tight spaces, you must account for the mirrors, as they can extend the overall space you need to clear.

2. The body of the bus may sway on uneven roadways, which can affect your ability to navigate through narrow areas safely. This swaying can cause the vehicle to require more space than what is indicated by its width on paper.

Both of these considerations highlight the importance of being aware of the vehicle's actual dimensions in real-world conditions, not just what is recorded in vehicle documents. Ignoring these factors can lead to accidents or collisions in tight spaces, which underlines the necessity of careful driving and awareness as mandated by German traffic laws.
