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

When driving a bus through narrow passageways, it's crucial to consider both the projection of the outside rear-view mirrors and the potential sway of the vehicle due to uneven roadway conditions.

1. The outside rear-view mirrors extending beyond the vehicle width means they can catch obstacles or pedestrians that would otherwise be outside the driver's line of sight. This is critical for safety, hence the regulation emphasizes awareness of this projection.

2. The body sway, especially on uneven roads, can lead to the vehicle's sideline moving significantly, which may not coincide with the driver's perception. This could result in collisions with obstacles adjacent to the road.

In summary, recognizing both factors ensures safe navigation through confined spaces, aligning with traffic rules designed to protect not only the driver but also pedestrians and other road users. Selecting both options is essential for full compliance and safety awareness.
