<p>An angularly adjustable side view mirror mounted upon a first vehicle is normally positioned to display to the driver reflections of the area at the side and rear of the vehicle. The mirror is temporarily angularly adjusted by a motor, out of its normal position into a temporary position which displays to the driver a following vehicle that is momentarily located in the first vehicle's side blind spot area. The motor angularly turns the mirror a predetermined amount from its pre-set normal position to its pre-determined temporary position and then back to its normal position in response to signals from a detector. The detector senses the presence of a following vehicle in the blind spot area and, consequently, activates the motor to move and hold the mirror in the temporary blind spot area viewing position while the vehicle is located therein.</p> |
