The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.

tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.
The convex exterior mirrors provide a larger
field of vision.
