Driver behavior in obtaining information through rearview mirrors and head turns was analyzed for novice, young experienced, and mature drivers during daytime driving on a freeway route. No significantly different mirror sampling pattems were observed when the horizontal fields of view of the plane left side mirror and inside mirrors were increased by 25 percent. In a system with a convex mirror mounted on the right side, the mature driver utilized the convex mirror more frequently than the young experienced and novice drivers.

An analysis of recent data on the effect of training with a convex mirror on the right side by drivers who are uninitiated and by those who are experienced with convex mirrors will also be discussed.
