Convex mirrors are designed to give a wider field of view; however, they do distort the size and distance of objects. The primary function of these mirrors is to allow drivers to see more area than they would with a flat or concave mirror. This means that while they provide a larger perspective, they do not accurately reflect the true size of people or objects nor their distance from the bus. Items appear smaller than they actually are, and their distances can be misleading, which is critical for a bus driver to understand for safety reasons.

This distortion makes it necessary for drivers to rely on other methods, such as direct observation or using additional mirrors, to accurately gauge the proximity and size of objects in their vicinity. Therefore, stating that convex mirrors provide an accurate representation of size and distance is incorrect.
