A wind deflector for use at the forward exterior of the side windows of a tractor or truck for diverting air currents away from the window and enabling the driver or passenger to travel in comfort with the window open comprises a transparent vertically elongated thick sheet or panel of plastic with the top and bottom ends bent in the same direction to form end flanges. A threaded stud extends outwardly through a reinforcing metal plate and the bent end flanges. Adjustably clamped along the projecting threaded stud is a clamp arm bracket, the outer end of which is provided with a tubular clamp which is adapted to encircle and clamp on a rear view mirror bracket arm or strut. The encircling portion of the bracket clamp is generally tangent to the clamp arm bracket. The bracket clamp may be adjusted radially along the stud, or inverted in order properly to engage the mirror arm or strut. Where the lower mirror arm or strut is inclined, the lower clamp arm bracket may be twisted properly to engage either the fore or aft inclined strut or mirror bracket arm. Alternatively, the lower end of each plastic sheet may be bent at an angle, with the attached clamp arm bracket remaining untwisted. The right and left hand side deflectors in such case may be a mirror image of each other. The deflectors may readily be adjusted to direct air flow away from the open window and across the reflective face of the rear view mirror, thus assisting in maintaining the mirror clean while also reducing drag. More importantly, the driver or passenger may travel in comfort with the window open.
