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

Your answer is correct. When driving a bus through narrow passageways, you need to remember that the outside rear-view mirrors typically extend beyond the official vehicle width stated in the vehicle documents, so they are at extra risk of hitting obstacles. Also, if the roadway is uneven, the body of the bus might sway, increasing the risk of contact with nearby objects. These factors require you to be extra cautious in narrow spaces. The statement that the mirrors are already included in the stated vehicle width is incorrect; usually, the vehicle width in the documents refers to just the body without the mirrors. Knowing this helps you better judge the actual space needed and avoid collisions in tight spots.
