Quarter glass on automobiles may be a side window in the front door or located on each side of the car in the back. Only some cars have them in the front. In some cases the fixed quarter glass may set in the corner of the vehicle.Quarter glass is also sometimes called a valence window.

This window may be set on hinges and is then also known as a Quarter Panel Glass. Most often found on older vehicles on the quarter panel of the body, it is a small roughly triangular shaped glass in the back of the car separate from the main window that rolls down, or It has hinges and a latch, thus it can be opened for additional ventilation. Most vehicles since the 1960s have removed this feature for cleaner styling, known as "ventless" windows. Some vehicles also have glass that rolls down like a regular window or have hinged opening vent quarter windows for rear seat passengers. This may be a side window between the B-pillar and the C-pillar, and in the case of minivans between the C and D-pillars (examples include th Chrysler Town and Country.
They can also be non-movable and mounted in the door itself because that section of the rear side glass would not be able to slide down because of the cut out in the rear doors to clear the rear wheel housings. The fixed portion of the glass is separated from the main window that rolls down by a slim opaque vertical bar (see top left image of a close-up of rear door).

A quarter glass can be found set in the body ahead of the front door opening or back quarter panel (examples include the Chevrolet Lumina and eighth generation Honda Civic 2 doors Coupe).
In some automobiles the fixed quarter glass may set in the corner of the vehicle. There are also designs that incorporate two quarter windows (see bottom right image) one that is part of the door and the second mounted in the roof pillar. This arrangement may help to increase driver visibility
