Somebody just got killed while sitting in the driver's seat of a vehicle. Said person's body will, almost inevitably, fall forward, their head hitting the steering wheel and activating the horn. The constant droning draws everyone's attention and punctuates what just transpired.
Sister trope to Dead Foot Leadfoot.
- Double Subverted in the end of the so-called "Banned Xbox Commercial", where a taxi driver seemingly refuses to participate in the on-going flashmob (where the participants pretend to shoot each other) because he is taking a call, but then does it, anyway, falling "dead" on the steering wheel (and the horn).
- Happens in Batman: Mask of the Phantasm when the Phantasm kills one of the mafiosi inside his own car.
- Chinatown ends with Evelyn jumping in her car and trying to escape from the Big Bad, her insanely evil father Noah Cross. Shots are fired, there's a sound of a crash, and the sound of a droning car horn. A dead Evelyn has collapsed on the car horn. Cue Downer Ending.
- Subverted in Halloween 5: The Revenge of Michael Myers, after his car crashes into a tree. Initially, the three people he's been pursuing are relieved at the sound of the car horn, assuming this trope. Their facial expressions turn to horror when the noise stops, revealing that of course, Myers has survived.
- Non-lethal version near the end of Get Out. When Chris crashes the car against a tree, his head comes to rest on the wheel which activates the horn. It only stops when Chris comes to and lifts his head.
- Triple 9: When the gang are meeting to discuss Irina's offer, Russel's car rolls slowly round the corner, hits the wall, and stops. The horn starts blaring. When the door is opened, the gang finds a mortally wounded Russell slumped forward on the wheel.
- Scarecrow Slayer: When Karl swerves to avoid the Scarecrow, he crashes and face plants on the steering wheel, causing the horn to blare.
- D-Tox: When the truck carrying Hank and Gilbert crashes, Hank face plants on the steering wheel, setting the horn blaring. This alerts Malloy inside the rehab centre that something has gone wrong.
- AMC's The Walking Dead had a long story arc with the protagonists trying to lead an incredibly large zombie herd away from their safe haven, Alexandria. The ruse fails when a semi-trailer crashes into the town walls, and the driver, slumping over, sounds the horn, leading much of the horde back to them.
- Midsomer Murders:
- Not dead but unconscious. The Teaser to "The Silent Land" ends with Joyce crashing her car. The scene fades to the credits with the horn blaring as Joyce slumps unconscious on the steering wheel.
- In "Death and the Divas", an attempted murder by cutting the victim's brake lines end with the intended victim face planted on the steering wheel and the horn blaring.
- The Sopranos: When The Mafia disposes of two would-be assassins to be absolutely certain that they won't tell tales, they crash their car so the dead driver slumps over and sounds the horn as the mobsters make their own getaway.
- Amen. When the gang tries to break into a piano store to return one that was stolen, they appoint the elderly Rolly as the lookout for the police. When the cops bust them anyway, they realize that Rolly has fallen asleep when they hear the sound of the car horn.
- In the Lifetime movie Sleeping With The Devil, a woman deliberately invokes this (although she's merely injured, not dead) in an attempt to call for help, having just been shot several times by the hitman hired by her ex-boyfriend to kill her.
- Not dead but merely dazed: In the Better Call Saul episode "Nailed", Mike lays down an improvised spike strip made from a garden hose to ambush one of Hector Salamanca's couriers. When the courier's truck hits the strip, he loses control and swerves off the road into a ditch, striking his head on the steering wheel and activates the horn.
- Murder, She Wrote: Happens when a van crashes during an attempted prison breakout at the start of "Trials and Tribulations".
- Happens when a drugged driver falls asleep at the wheel and runs off the road in "Jackpot".
- Happens again in "Disarmed & Dangerous". A crook shoots at Brass and Ray from a moving car. Brass returns fire and kills the driver, and the car crashes into a parked car where the driver faceplants on the horn.
- A non-lethal version in Frequency. After Frank's car gets t-boned by another car, his head hits the steering wheel which causes a continuous honking.
- Between: When Chuck and his small band of cohorts makes their escape attempt, Samantha is shot by a sniper as they stop to make plans; resulting in this trope.
- Cannon: Happens in "Flight Plan", when Cannon is knocked unconscious and placed in car with the engine running in an attempt to asphyxiate him. He slumps on the steering wheel causing the horn to blare and making the bad guy come back and shove him off the horn.
- Implied in Vigilante8 when you wear down your opponent's life bar completely and the horn goes off. You now have a few seconds to "Total" his vehicle.
- In Modern Warfare 2, the player character and his squad are watching a person of interest, who suddenly draws a huge gun and shoots wildly, killing the driver of their vehicle, who slumps forward. The honking is audible as you continue the chase on foot for several blocks.
