Rear-hinged doors were common on cars manufactured in the first half of the 20th century, including the iconic Citroën Traction Avant. In the era before seat belts, the accidental opening of such doors meant that there was a greater risk of falling out of the vehicle compared to front-hinged doors, where airflow pushed the doors closed rather than opening them further.

Rear-hinged doors were especially popular with mobsters in the gangster era of the 1930s, supposedly owing to the ease of pushing passengers out of moving vehicles with the air around the moving car holding the door open, according to Dave Brownell, the former editor of Hemmings Motor News.

After World War II, rear-hinged doors were mostly limited to rear doors of four-door sedans. The best-known use of rear-hinged doors on post-World War II American automobiles was the Lincoln Continental 4-door convertibles and sedans (1961–1969), Cadillac Eldorado Brougham (1956–1959) four-door sedans, and Ford Thunderbird (1967–1971) four-door sedans. The British Rover P4 used rear-hinged doors at the rear. German Goggomobil saloons and coupes had two-door bodies with rear-hinged doors until 1964.Goggomobil The French, hand-made Facel Vega Excellence offered a four-door hardtop with a Chrysler-sourced Hemi V8 beginning in 1954.

In 2003, the new Rolls-Royce Phantom car reintroduced independent rear-hinged doors in luxury vehicle applications. Other luxury models with rear-hinged doors include the Spyker D8 and the Rolls-Royce Phantom Drophead Coupe four-seat convertible. The most recent mass-produced model with such doors may be the Opel Meriva,{{Cite web |url=https://jalopnik.com/opel-vauxhall-meriva-giant-jelly-bean-gets-suicide-doo-5440497 |title=Opel/Vauxhall Meriva: Giant Jelly Bean Gets Suicide Doors |first=Wes |last=Siler |date=January 5, 2010 |website=Jalopnik}} followed by the Rolls-Royce Cullinan in 2018, and a few Chinese electric vehicles including the Singulato iS6 in 2018 and HiPhi X in 2020.{{Cite web |url=https://www.motor1.com/news/240996/singulato-is6-revealed/ |title=Singulato iS6 Electric SUV Has Suicide Doors And Huge Touchscreen |date=May 3, 2018 |first=Adrian |last=Padeanu |website=Motor1.com}}{{Cite web |url=https://www.carscoops.com/2020/08/human-horizons-hiphi-x-6-seater-electric-suv-makes-the-tesla-model-xs-falcon-doors-look-normal/ |title=Human Horizons HiPhi X 6-Seater Electric SUV Makes The Tesla Model X's Falcon Doors Look Normal |first=Brad |last=Anderson |date=14 August 2020 |website=Carscoops.com}} Lincoln announced that 80 limited-edition 2019 Continentals would be made with "coach" doors, marking the Continental's 80th anniversary.{{cite news |last=Howard |first=Phoebe Wall |url=https://www.freep.com/story/money/cars/2018/12/17/lincoln-continental-makes-vintage-limited-edition/2311731002/ |title=Lincoln Continental: A limited-edition design of 80 new cars for $100,000 each |work=Detroit Free Press |publisher=USA Today |date=2018-12-17 |access-date=2018-12-17}} The 2020 Citroen Ami electric vehicle is unusual in having a suicide door for the driver but a conventional door for the passenger, as the doors are identical units that are not differentiated by side.

In the early 2000s, rear-hinged rear doors that are held closed by the front doors, and cannot be opened until released by opening the front door on the same side (hinged at the front), have appeared on a number of vehicles. Such doors may be referred to as clamshell doors. Examples include extended-cab pickup trucks, the Saturn SC, Saturn Ion Quad Coupe, Honda Element, Toyota FJ Cruiser, BMW i3, Mini Cooper Clubman, Mazda RX-8, Mazda MX-30 and Fiat 500 3+1.{{Cite web |title=Fiat 500 Electric 3+1 Debuts With Tiny Third Door |date=October 22, 2020 |first=Angel |last=Sergeev |url=https://www.motor1.com/news/450291/fiat-500-electric-3-plus-1-debut/ |access-date=2020-10-29 |website=Motor1.com |language=en}}

Rear passenger rear-hinged doors had long been used on Austin FX4 London taxis, discontinued on their successors the TX1, TXII and TX4, but reintroduced in the 2018 LEVC TX.

Several concept cars have featured rear-hinged doors, such as the Lincoln C, a hatchback with no B-pillar and rear-hinged doors at the rear, or the Carbon Motors Corporation E7, a police car with rear rear-hinged doors designed to aid officers getting handcuffed passengers in and out of the back seat. The Kia Naimo, an electric concept car, also has rear suicide doors.{{cite news |title=Kia Naimo concept EV debuts: 93mph, 124-mile range, and suicide doors |first=Michael |last=Gorman |url=https://www.engadget.com/2011/04/01/kia-naimo-concept-ev-debuts-93mph-124-mile-range-and-suicide/ |work=Engadget |date=1 April 2011 |access-date=6 January 2013}}

Other car manufacturers which have produced models with suicide doors include Citroën, Lancia, Opel, Panhard, Rover, Saab, Saturn, Škoda, Studebaker, Ferrari, Mazda and Volkswagen.

Rear-hinged doors make entering and exiting a vehicle easier, allowing a passenger to enter by turning to sit and exit by stepping forward and out. This is important for passengers who need to make a dignified entrance; the UK State Bentley has rear-opening passenger doors that are broader than usual and open very wide, allowing the monarch to exit the car in a dignified way.{{Cite news |title=Prince Philip: The State Bentley and five other features of the duke's funeral explained |last=Parkinson |first=Justin |website=BBC News |date=17 April 2021 |url= https://www.bbc.co.uk/news/uk-56762822}}

In combination with traditional front doors, rear-hinged doors allow chauffeurs easier access to the rear door. In Austin FX4 taxis, drivers were able to reach the rear exterior door handle through the driver's window without getting out of the vehicle.{{Cite web |title=Austin FX4 Black Cab – taxi! |last=Berridge |first=Declan |work=AROnline |date=16 May 2020 |url=https://www.aronline.co.uk/cars/austin/fx4/ado6-development-story/}}

Rear-hinged doors also allow a better position for a person installing a child seat into the back seat of a vehicle than conventional doors, while being simpler and cheaper to build than the sliding doors commonly used on minivans. The Opel Meriva B compact MPV introduced in 2010 had such doors.{{Citation needed|date=February 2016}}

The combination of front-hinged front doors and rear-hinged rear doors allows for a design without the B-pillar, creating a large opening for entering and exiting the vehicle.

When front doors are directly adjacent to rear suicide doors, exiting and entering the vehicle can be awkward if people try to use the front and back doors at the same time.

There are also a number of safety hazards:

• Aerodynamic factors forcing rear-hinged doors open at speed in older cars. In 1969, Consumer Reports reported this problem on a Subaru 360.{{cite web |url=http://www.mysubaru360.com/manuals_and_documents/Subaru_360_Consumer_Reports_April_69.pdf |title=The Subaru 360 (Not Acceptable) |work=Consumer Reports |pages=220–222 |date=April 1969 |access-date=24 January 2011}}
• If a person not wearing a seat belt falls out of a moving car with a coach door, the door can catch them and drag them along the road at speed, causing serious injuries.
• If a person exits a vehicle while parallel parked and a car hits the door from the rear, the person would be crushed instead of the door being ripped off.

Car manufacturers mitigate these hazards with such safety features as seat belts, and locks requiring front-hinged doors be open before permitting rear-hinged doors to open.
