"Convex mirrors are used to provide a wider Field_of_viewthan a flat mirror, and are often used on vehicles, especially large trucks, to minimise Blind_spot_(automobile)."

Convex gives you the widest "field of view" (so someone does not have to be right behind you in order for you to see them).
It gives an erect image and as the image is dimished it would cover a wide range. Though the image is virtual it could be seen by human eyes. Because of all these we use convex mirror as a rear view mirror in vehicles.
The most common use of a convex mirror is as view finder in vehicles. It is used in supermarkets and stores for surveillance. For making sun glasses and telescopes also convex mirror is used.
As it shows a larger part of area in a smaller and nearer way.

Yes. In convex mirrors, the image is always erect and diminished, at whatever distance the object may be in front of the mirror. The convex mirror has a wide field of view and hence is used as a rear view( or driving) mirror in vehicles, to view the traffic behind.

This gives the driver a wider field of vision. Usually only the passenger side mirror is convex. The reflective surface of a convex mirror curves outward like the outer surface of a ball or globe. An object observed by looking at its reflection in a convex mirror appears to be smaller than actual size.

A convex mirror is used as the wing mirror on a vehicle, not as the internal rear view mirror. The advantage of the convex mirror is that it gives a wider field of view, but it must be used with caution, because it distorts distances, making it hard to judge how near another object is.
convex mirror provide erect small and virtual image of the object.these are used in side view mirrors of vehicles so that the driver can have a better view of traffic behind.

Both give diminished, virtual, erect image. Hence convex mirror is used as rear view glass in case of vehicles near by the drivers. Concave lens is used to correct short sightedness.
They use convex mirrors to give a wider view.
