A character is coming down the sidewalk. Maybe they're really moving because they're being chased by the cops. Maybe they're just strolling, but they aren't watching where they're going. Suddenly, the door to a car parked on the street swings open, and *THUD* -- they slam right into it. Also known as "getting doored" or a "door prize" by cyclists.

A common variant is to have the tripper on a bike and be sent head over heels. Bonus points if the door opener leans out and delivers a QuipToBlack. A cousin to the OffhandBackhand. Compare with LowClearance.

Not to be confused with a tripwire for use on cars. And no, [[IThoughtItMeant Toyota doesn't have a car called the Tripwire.]] SubTrope to TaeKwonDoor. Compare with CarFu. Contrast with PedestrianCrushesCar. See also TheDoorSlamsYou.

He runs away down the sidewalk... right into the suddenly-opened door of the car in which Lucas was hiding.
* ''Film/HotFuzz'' uses the bicycle version on a lady rolling down the street, GunsAkimbo.

* In ''Film/{{Inception}}'', Saito floors the Cobol Mercenaries with his car door to rescue Cobb.

* How does John Wick deal with a motorcycle pursuer in ''Film/JohnWickChapter2''? By opening the door and slamming the brakes of course! This is a rare moving-vehicle version of this trope.

* An EvilLawyerJoke has this as the punchline: A man picks up a hitchhiking priest on the highway. Several minutes later, he sees a hitchhiking lawyer, and immediately speeds up to run him over. At the last second, he remembers he has a priest in the back seat and swerves, narrowly missing the lawyer.
-->'''Man:''' ''[trying to play it off as an accident]'' Wow, that was close! I almost ran over that lawyer!\\
'''Priest:''' Do not worry, my son. I got him with my door.
* In an old Australian joke, a wealthy city-dweller in a shiny new Mercedes picks up a swagman who obviously hasn't been in a car since the Model T Ford. The swaggie asks what all of the bells and whistles do, and when he gets to the hood ornament, the city-dweller decides to have some fun with him and [[BlackComedy says it's a sight to make it easier to run over cyclists]]. Now, some cyclists are just up ahead, so the city-dweller moves as if to hit one, then swerves at the last second, only to hear a thump. He looks back to see the cyclist lying in the road, obviously in considerable pain. Then the swagman says, "Next time you get a service, you should get your sights checked - if I hadn't opened the door, you would have missed him!"

* ''Webcomic/TheAdventuresOfDrMcNinja'': Dr. [=McNinja=] [[http://drmcninja.com/page.php?pageNum=22&issue=4 knows how it's done.]]

[[folder:Video Games]]
* Can be pulled off in ''VideoGame/GrandTheftAutoIV'' by backing up while the car door is ajar, and used to knock over hapless pedestrians or annoying foes trying to kill you. Doubles as CarFu.
* In ''VideoGame/{{Carmageddon}} TDR 2000'', as long as the doors are still on the vehicle they can be opened to sweep zombie crowds. Depending on the active buff/debuff, it can be useful against other cars, but that's likely to remove the doors.
* You can open car doors in ''Videogame/StateOfDecay'' to smack zombies. It's far superior to trying to run them over, as it results in less damage to the vehicle. Fittingly, the achievement for doing so is Tallahassee's advice in ''Film/{{Zombieland}}'': "Gotta enjoy the little things."
* ''VideoGame/SleepingDogs'' lets you open your door while driving in order to perform drive-by shootings or prepare to leap onto an adjacent vehicle and hijack it from the roof. (It's every bit as awesome as it sounds.) Or you can take advantage of its functional collision physics and simply use it to knock people off their motorcycles.

[[folder:Web Original]]
* [[http://www.stickdeath.com Stick Death]] has a series of ads for SD Security Systems, which makes car theft prevention devices that kill the potential thief. One of these automatically opens the door hard enough to fling the would-be carjacker 50 feet.

* One ''WesternAnimation/RobotChicken'' sketch has a guy stuck in traffic do this to a motorcyclist cruising between lanes.

* Bob Roll, a UsefulNotes/TourDeFrance commentator for Versus and former cyclist, was at the medic car when he was in the tour. The doctor then accidentally opened the car door, sending Bob flying.
