Which glass on a vehicle is fixed and does not roll up and down?

• A. Door Glass
• B. Vent Glass
• C. Windshield
• D. Rear Window

Answer: (B)

Vent glass is the small, fixed window in the door that doesn’t move. It’s designed mainly for ventilation, so it stays in place rather than rolling up and down. The main side door glass is the one that slides, while the windshield and rear window are typically fixed to the vehicle’s structure and do not operate. So, the glass meant to remain stationary for ventilation purposes is vent glass.
