• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

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" 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 Quip to Black. A cousin to the Offhand Backhand.

Not to be confused with a tripwire for use on cars. See also The Door Slams You.

Examples of Toyota Tripwire include:


  • An Australian car insurance ad has a guy trying to pick the lock on the car door. Suddenly, the door opens and knocks him out, before closing again. The hook was, "Unless your car can take care of itself, you should talk to us."


  • Empire Records uses this trope during the scene where Lucas is chasing Warren after the latter was caught shoplifting. After finding different escape routes blocked by Lucas more than once, Warren finally finds himself apparently in the clear. He runs away down the sidewalk... right into the suddenly-opened door of the car in which Lucas was hiding.
  • Hot Fuzz uses the bicycle version on a lady rolling down the street, Guns Akimbo.
  • Hammond (Eddie Murphy) did this to a criminal in 48 Hours. He then adds, "I bet that hurts. A lot."
  • The 2007 Transformers movie uses this with Barricade attacking Sam.
  • Played the motorbike variation straight in 2003's The Italian Job.
  • The Gumball Rally pulls this one on the accident prone Lapchik. On a motorcycle.
  • Happens to Gregor when he's running away in Arles in Ronin.
  • Happens twice in Children of Men, to the same guy. Once using the motorcycle gag (albeit, the car is reversing to accomplish this), and once chasing a car downhill. On foot.
    • Although the engine isn't on, a situation which Theo is frantically trying to rectify at the time.
      • Probably the only car chase where the car is in neutral.
  • Tallahassee of Zombieland loves doing this to any zombie he's driving by.
  • Happens in the movie Click. It's then repeated multiple times by the protagonist's reality altering remote control.
  • In Wayne's World a variant of the bike version happens to Wayne's ex girlfriend except she strikes the front wing of a car parked in a driveway.
  • A deleted scene from The Incredibles puts a twist on this, when super-strong Mr. Incredible uses his arm to knock a motorcyclist fleeing the cops off his bike.
  • In Wild Target, Tony gets this as he, Victor, and Rose escape by car in his first scene.
  • In Inception, Saito floors the Cobol Mercenaries with his car door to rescue Cobb.
  • Smith uses a car door to take out a machine-gun-toting mook hanging out of the side of a van in Shoot Em Up.
  • The Ewoks pull this on a speedbike-riding stormtrooper in Return of the Jedi.

Live Action TV

  • An FBI agent drops a sex offender with this in the season 4 pilot of Veronica Mars.
  • Knight Rider, featuring a car that can take care of itself quite handily, frequently featured variations on this trope.
  • An episode of The Bill had this happen to a criminal fleeing the police. His lawyer was all set to make an official complaint against the officers involved, but the revelation that it was actually a member of the public who knocked down his client took the wind out of his sails.
  • Sledge Hammer caught a snatch thief in the pilot by opening the door of his car to clock the perp.
  • A variation shows up in a first-season episode of Law & Order, when Det. Logan hides around a corner and swings a trash can lid into a fleeing suspect's face.
  • Lost: This happens to Sawyer in the background of one of the many, many flashbacks of the series.
  • This happened to Deputy Junior a few times in Reno 911.
  • Brian 'Memory' Lane does this in the New Tricks episode "Good Morning Lemmings": opening the door of the surveilance van to flatten a fleeing suspect.
  • Magda Szubanski stirred up a hornet's nest by suggesting on an episode of Good News Week that drivers should deliberately do this to cyclists.
  • One of AJ's 'junior mafia' buddies does this accidentally on The Sopranos. When the biker gets up to complain, the guy beats him up further.
  • Rizzoli's brother does this to a fleeing suspect in an episode of Rizzoli and Isles, so he can keep to the Exact Words of his promise to Rizzoli that he would not leave the car.


  • The song "Blow em Away" by Chuck Brodsky has a line where the protagonist intentionally does this to a motorcyclist for "cutting in line" by driving between the lanes during a traffic jam.
  • Weird Al did this, too, in "Traffic Jam": "There's a motorcycle zooming by me / Watch what happens when I open my door."

Stand Up Comedy

  • Denis Leary talks about this when ranting about cyclists in New York.
  • Jeff Dunham's Walter puppet talks about running down a man who parks in handicap spots to "make an honest man out of him." When his actually handicapped mother gets out of the car to scream at him, Walter takes her out with the door.
  • Louis CK talked about an incident in which he witnessed a cyclist about to run into a car door. He had several seconds to warn him, but wasn't able to come up with an adequate warning for the cyclist in time, so he just shouted "Bad thing!" to him.

Web Comics

Video Games

  • Can be pulled off in Grand Theft Auto IV by backing up while the car door is ajar, and used to knock over hapless pedestrians or annoying foes trying to kill you. Doubles are Car Fu.
  • In 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.

Web Original

  • 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.

Western Animation

  • Ed, Edd 'n' Eddy has used a locker door for this gag.
  • This happened once with Eugene in Hey Arnold!, with the bike variant, except the door is open to start with and he spots it. However, the bike's brake cables are broken, and, not surprisingly (it is Eugene, after all), he ends up in the hospital in a full-body cast.
  • One Robot Chicken sketch has a guy stuck in traffic do this to a motorcyclist cruising between lanes.

Real Life

  • The Irish minister for the environment once caused a number of letters to the editor when he opened the door of his limo and clocked a cyclist in this manner.
  • A commonplace fear of many cyclists. Even if it doesn't happen that often, there are the accidents caused by swerving to avoid it.
    • Depending on where you ride, it is actually frighteningly common, especially in cities like Boston where streets are narrow with on-street parking. Also, while pedestrians aren't usually seriously hurt by getting doored, bicycles have a lot more momentum. So drivers, look before you unlatch, and cyclists, assume every car is loaded.
      • You can try to look in the driver or passenger side mirror. If you're cycling next to the cars, chances are you can see the inside of the car in the side mirrors. If you see a person, you can maybe also see whether they intend to open the door or not and where they're looking. At any rate, lower your speed near parked cars just in case. You can't see the backseat of the car in the side mirrors.
  • Bob Roll, a Tour de France 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. The whole event was caught on video. Keep in mind that a member of the official medical staff did this to a cyclist in the Tour de France.
