What should the outside convex mirrors be adjusted to see?

The correct choice is to adjust the outside convex mirrors to see the entire area to the rear of the mirror along the side of the bus. This is crucial for ensuring safety while driving large vehicles like a bus, which have significant blind spots. By positioning the mirrors to cover the area behind the bus, the driver can detect vehicles, pedestrians, and obstacles that may not be visible through standard mirrors or the rear view.

Convex mirrors provide a wider field of view compared to flat mirrors, which allows for better visibility of the surroundings. Adjusting them correctly helps reduce the risk of accidents when changing lanes or making turns. This procedure is an important part of pre-trip inspections, ensuring that the driver can maintain awareness of their environment and navigate safely.

The other options highlight either a limited field of view or specific distances that do not encompass the necessary areas for safe operation. It is essential for drivers to focus on a broad perspective rather than just specific points in front or behind the bus.
