Abstract: A convex mirror has a frosted non-reflective elongated and horizontal line, approximately midway of the mirror and of a width less than the thickness of the mirror, and a light source is disposed adjacent the reflective surface with a colored filter positioned between the light source and the frosted line whereby a predetermined safe distance is indicated for changing lanes into a position in front of the immediately passed vehicle. In another mirror, safe turning distances are indicated by predetermined lines extending vertically of the convex mirror.
