An apparatus and method in a tractor-trailer type vehicle for insuring the ability to change lanes without colliding with other vehicles traveling in lanes adjacent the lanes adjacent the lane in which the vehicle is traveling. The side rear view mirror is motorized to encompass fields of view that include both adjacent and non-adjacent lanes without attention on the part of the operator: The minor is rotated at a minimum rate of speed to prevent confusion on the part of the operator during travel of the mirror between the two positions. The normal home position setpoint and the outer or scanned position setpoint are adjustable. The activation switch may be on the gear shift lever, the turn signal, or the control box for the motor.
