What is the characteristic of curved (convex or spot) mirrors on buses?

The characteristic of curved (convex or spot) mirrors on buses is that they make things seem smaller and further away. This design allows drivers to see a wider field of view, which is crucial for safety, particularly when maneuvering larger vehicles. The convex shape of the mirror allows it to capture more surroundings, helping the driver become more aware of potential obstacles or pedestrians that may be in the vicinity, especially in blind spots.

While this reduced size can be a disadvantage in terms of accurately judging the distance to objects, it is essential for the increased visibility and awareness it provides. Drivers learn to adjust their perception when using these mirrors, understanding that although the objects appear smaller, they do allow for a more comprehensive view of the area around the bus, enhancing overall safety on the road.

Other options mention aspects that do not align with the primary function and characteristic of curved mirrors. For instance, mirrors that show objects at their actual size are typically flat mirrors, and while convex mirrors do enhance depth perception in a way, their main characteristic is the visual distortion caused by making objects appear smaller. The notion that they are not used for safety purposes is inaccurate, as their purpose is fundamentally linked to improving vehicular safety.
