A "Passenger Door" is a door on a vehicle that provides access for passengers to enter and exit. Typically found on the sides of cars, it is designed to open outward, allowing easy access to the interior. Passenger doors are usually equipped with handles, locks, and sometimes windows that can be rolled down or opened. In most vehicles, there are usually two or four passenger doors, depending on the design. These doors are an essential part of the vehicle's structure and safety features, contributing to the overall functionality and comfort of the car for its occupants.
