The car door is a type of door, usually hinged, but sometimes attached by other mechanisms such as tracks, in front of openings used for in and out of vehicles. The vehicle door can be opened to provide access to the opening, or closed to secure it. These doors can be opened manually, or supported electronically. Powered doors are usually found in minivans, high-end cars, or modified cars.

General design
Unlike other types of doors, the outside of the door contrasts in the design and finish of the interior (the interior is usually equipped with door cards or door panels ( in American English) that has decorative and functional features.
The outer side of the door is designed from steel or other materials such as the rest of the vehicle's exterior. In addition, the decorative appearance, which is usually colored with a design, is meant to match the outside of the other vehicle, the ultimate goal being to increase the overall aesthetic appeal of the vehicle.
A vehicle usually has two types of doors: the front door and the back door. The loose relation is: vehicle hood and vehicle trunk cover. There is also a door known as "hold" (see "door categorization" below)
The main security issue with the open vehicle door is the assumption on the night vehicle door can give warning to other vehicle drivers. Unfortunately it is estimated that more than 50 percent of all vehicle doors are not applied to vehicle door interiors such as light and/or reflectors. Unfortunately, this device does not need to comply with the Federal Federal Vehicle Safety Standard because there are no applicable standards. To make matters worse it is reported by the Fatal Accident Reporting System that by 2014 not one death is reported with someone outside the door of an open vehicle at night across the United States. New safety technologies such as delivering to the lower lower part of the vehicle door, highly reflective bands provide the ability of other vehicle drivers to see the doors of vehicles open at night (see US Patent No. 9308,859 for details including diagrams of typical applications )

Door lock and hook
Most vehicle doors are secured closed to the vehicle body with hooks that may be locked to prevent unauthorized access from outside. There are various car door locking systems. Door locks can be manual, or operated automatically, and can be operated centrally or individually. Also, they can be operated by remote control, with transmitters often integrated into the main access key/vehicle ignition keys.
In addition, the rear passenger door is often equipped with a child's safety lock to prevent children from leaving the vehicle unless the door is opened from the outside. It is also often used on police cars, to prevent suspected criminals from fleeing while in police custody.
Vehicle doors lock most of the current vehicles are usually operated using a handle that requires the user to draw , lift , or drag - with some power against the self themselves rather than push . There is a reason for this. In the late 1970s, some vehicles used an open push button to operate the door latch, such as certain Opel models. The unfortunate side effect of this design is that external objects touching the vehicle during a spinout can trigger a hook; the door will open and remove the passenger vehicle. Deaths that occur just like that lead to a landmark legal case Daly v. General Motors Corp. , 20 Cal. 3d 725 (1978), in which the California Supreme Court incorporates a strict product responsibility with a comparative error, and thus affirms the right of General Motors to introduce evidence that the late Kirk Daly flew out of his Opel not only because the door appeared open but because he was drunk and not wearing a seat belt.
The door switch
The door switch is a simple on/off mechanism connected to interior light (dome light), and may also be connected to warning lights, speakers or other devices, to notify the driver when the door is not closed. The door lamp is standard equipment on all cars. In American cars from the 1950s to the 1990s, they had bells or door dingers, along with check lights, whenever a door opened.
Windows
Most vehicle doors have windows, and most can be opened for many levels. Most car door windows are pulled down into the door body, and opened either by manual crank, or replaceable electric motor (electric car windows other than the driver's window can usually be controlled at both the door itself and centrally with additional control on the driver's position). In the past, certain retractable windows were operated by direct pressure (up or down), and held at the top by friction rather than by an internal lifting mechanism.
Other cars, especially older US-made vans, have installed windows with a folded lever mechanism to push and hold the window from its closed position.
Door brakes or fixed
Vehicle doors often include brakes, or 'fixed' ones, which slow down doors before closing, and also prevent doors from opening further than the design specifications. The current trend is to have a three-level door brake.
The door brake is because the doors in the first vehicle are heavy, so they have to be pushed hard to close them. Soon after, the automotive manufacturer managed to build a lighter door, but the user used to close the door by force so the door quickly became damaged. The door brake was then introduced to slow the door just before the door closed to prevent damage; this soon became the standard.
Categorization of doors
Hatchback and estate agencies or station wagons are sold as 'three-door' or 'five-door' models. In this case, the back door is classified as a door; this is due to enter the passenger compartment. With other vehicles such as saloons or sedans and coupà ©, trunk/luggage cover is not counted as a door with a definition because for separate storage compartments - the car is sold as 'two doors' or 'four doors'. This system is mainly used in Europe, and is less common in North America. In Europe, American-style labeling is sometimes used.
Usually in North America, cars are only sold as "two-door" or "four-door" models. This American-style labeling only covers passenger and driver doors, and does not hatch in hatchbacks and station wagons. This causes many who do not understand that hatching is counted as a door in Europe, whereas a cover for a closed bar is not.
Being locked
Some cyclists call colliding with open car doors as "checked doors". This usually happens when cyclists are riding alongside rows of parallel parked cars, and a driver suddenly opens his door in front of a cyclist without first finding out whether it is safe to do so. Major advances have been made to allow visual recognition of partially open vehicle doors to provide warning levels to cyclists and motor vehicle drivers especially at night. See US Pat. 9.469.246.
Vehicle door type
There are many types of vehicle doors, including the following:
Conventional door
The conventional door , also known as ordinary door is the type of door that hinges on the front edge of the door, allowing the door to swing out of the car's body. These doors are relatively safe, that if they are opened during a forward movement of the vehicle, the wind resistance will work against the opening door, and will effectively force its closure. Operation of a vehicle entrance, exit, or stand outside an open vehicle door is very dangerous especially at night even when looking in both directions. The problem is the door of the vehicle in most cases does not provide a visual warning to other vehicle drivers to allow avoiding the accident of other vehicle drivers to have time to take avoidance measures. New advancements have been made to enable viewing of open vehicle doors at night with the addition of highly reflective bands applied to the bottom of the bottom of the door of the vehicle (see US Patent No. 9308859). This new advancement allows the vehicle door to open even with those who block previous art systems such as reflectors or light by giving reflex reflectivity exceeding fifty percent of the vehicle door at the foot of a person blocking the door of an open vehicle at night.
Suicide door
Suicide door is the kind of door that depends on its trailing edge. The term "suicide door" is created because of the potential of the door to fly open when the latch is removed while the car is in motion. They are also called "kidnapper doors" for obvious reasons.
Scissor doors
Scissor doors are doors that rotate vertically upward, and rely on or near the edge of the windshield.
Butterfly door
The butterfly door is a kind of door that resembles a scissor door, but when the scissor door moves upward, the butterfly door also moves out, which makes it easy to enter/exit, and save space.
gull-wing door
Gull-wing doors are the type of doors that depend on their top edge, on the roof rather than the sides. They are named so because when it is opened, the doors evoke seagulls that open their wings.
Sliding door
The sliding door is a type of open door with horizontal or vertical shifts, where the door is mounted above, or suspended from the track. They are commonly used on the side of minivans, recreational activity vehicles, light commercial vehicles, minibuses and some buses as this allows a large opening for equipment to be loaded and unloaded without blocking access.
Canopy door
The canopy door is a type of door that is on top of the car and raised in a certain way, to provide access for passengers. This is similar to a plane canopy. There is no standard set for the canopy, so they can be hinged in front, side or back - although the hinges on the front are the most common. Canopy doors are rarely used in production cars, but are often used in 'closed' variants of Le Mans Prototype endurance racecar. They are also sometimes used on concept cars.
The door disappears
The missing door is a kind of slide below and below the vehicle. This type keeps all sides of the passenger compartment open, leaving only the threshold to step in and out. Also called jatech rotary drop door, or missing car door. One example of a car with a missing door is the Lincoln Mark VIII concept car.
