Door Glass is defined as which of the following?

• A. The glass on the door of the vehicle. This piece typically goes up and down
• B. Windshield
• C. The glass on the roof
• D. The glass on the side door

Answer: (A)

Door glass is the window that sits in the door of the vehicle and moves up and down when you operate the window regulator. This definition focuses on the location (in the door) and the function (able to slide up and down). It’s distinct from the windshield, which is the large front window, and from roof glass, which would be a sunroof or glass panel on the roof. The phrasing that specifies the glass on the door and its up-down movement precisely captures what “door glass” refers to in auto glass terminology.
