A vehicle door is a partition, typically hinged, but sometimes attached by other mechanisms such as tracks, in front of an opening which is used for entering and exiting a vehicle. A vehicle door can be opened to provide access to the opening, or closed to secure it. These doors are similar to doors used in buildings.

These doors can be opened manually, or powered electronically. Powered doors are usually found on minivans, high-end cars, or modified cars.

There are many different types of vehicle door. The following are the types:

A conventional door, also known as a regular door is a type of door that is hinged at the front-facing edge of the door, and so allows the door to swing outward from the body of the car. These doors are relatively safe, in that if they are opened during forward motion of the vehicle, the wind resistance will work against the opening door, and will effectively force its closure

Suicide doors are a type of door that is hinged on its trailing edge. The term 'suicide door' was coined due to the potential for the door to fly open should the latch be released during forward motion of the vehicle.
