In fiction, picking up a hitchhiker is an exceptionally risky proposition, as there's a good chance they're either a) a Serial Killer who will murder you, or b) a wanted criminal (or escaped convict) who will force you to help them evade the authorities, then murder you. This trope can also cover rape, robbery, and other kinds of violence or maltreatment inflicted by hitchhikers on those who pick them up.
See also Beware of Hitchhiking Ghosts, the difference being that hitchhiking ghosts are generally supernatural and not always malevolent. Also see Not My Driver, for when a driver that the passenger already trusts is replaced by a hostile person, or when the vehicle is an official taxi.
- Played for laughs in a Bud Light commercial, where a guy driving through the woods in the middle of the night decides to pick up a shifty-looking hitchhiker simply because he has Bud Light — even though, as his passenger points out, "He has an axe!" The hitcher claims that the axe is a bottle opener, and the driver promptly invites him in. He later picks up an even shadier hitcher because he has a six-pack of Bud Light, and the first hitcher objects.
Driver: Look. He has Bud Light.
Hitcher: And a chainsaw!
- One issue of G.I. Joe: Special Missions has an operation go seriously bad with Outback being the only one to escape. At one point, he buys a truck from a gypsy and tries to drive to a friendly country. He picks up a hitchhiker because he figures the authorities are looking for just him and a second person in the vehicle might throw them off. The hitchhiker then tries to hijack the truck and rob him. This quickly turns into Mugging the Monster due to Outback being a highly trained soldier who then kills the hitchhiker and crashes the truck.
- Tiny Toon Adventures: How I Spent My Vacation has Mr. Hitcher, a chainsaw-wielding psychotic killer with a strange aversion to pork and duck. When Hamton's Family, who are on their way to HappyWorldLand, pick him up, they don't see him as a psychotic killer. Plucky, who is going to HappyWorldLand with them, is the only one who does, as he listened to a radio broadcast describing Mr. Hitcher as an escaped convict. Even worse, before he could get the important number to call the authorities, Hamton's Mom shut off the radio, saying there was too much sensationalism in the media. After narrowly avoiding getting sliced by Mr. Hitcher's chainsaw, it is later revealed that Hamton gave Mr. Hitcher Plucky's address, rather than his own, and at the end of the movie, Mr. Hitcher is seen chasing and trying to attack Plucky after Hamton shows him to the class.
- The Hitcher (1986) is about a driver who is stalked and manipulated by a hitchhiking spree killer after foiling the man's direct attempt on his life. Screenwriter Eric Red said the story was inspired by song "Riders on the Storm" (see Music, below). Was later remade in 2007.
- Detour uses a variant: the driver dies accidentally, and the rider (who is the protagonist) seizes the opportunity to steal his identity. Later, he picks up a hitcher of his own — who figures out what happened and blackmails him over it.
- Downplayed in Thelma & Louise, in which an otherwise friendly hitchhiker ends up stealing all their money.
- The 1953 film The Hitch-Hiker is about a hitchhiking robber/murderer in the southwestern U.S. who, after a Run for the Border, gets picked up by two vacationing Americans. He forces them to transport him south through Baja California, intending to kill them when he reaches his planned destination.
- The Anti-Hero protagonist Nomi Malone from Showgirls thumbs a ride to Las Vegas from a man in a pick-up truck. En route, the man suggests sex-for-mileage; Nomi and her switchblade vehemently disagree.

She shrieks, "You stole my luggage!" and resumes slashing at him while he's driving.
- There is a hitchhiking Serial Killer on the loose in the comedy There's Something About Mary. The cops find the body he was carrying and peg the main character as a guy who kills hitchhikers, starting a hilarious Mistaken Confession.
- The Texas Chain Saw Massacre (1974): The hitchhiker travels with the group for a bit and start talking about his family who worked at the old slaughterhouse. He borrows Franklin's pocket-knife and cuts himself, then takes a Polaroid picture of the others and demands money for it. When they refuse to pay, he burns the photo and slashes Franklin's arm with a straight razor. The group forces him out of the van and drive on.
- Dumb and Dumber: Mental (one of the hitmen that are pursuing Harry and Lloyd) pretends to have car trouble and hitches a ride with them in order to find out that they know about the Briefcase Full of Money MacGuffin that they unknowingly carry and to check out if the Mistaken for Badass beliefs that he and his employers have are actually well-founded. He nearly becomes a straight use of this trope when he almost pulls a gun on them because they are annoying him so much (but their picking up some Mexican immigrants prevents him from doing so) and then it (accidentally) becomes the inverted version when Harry and Lloyd pull a prank that makes his ulcer act up and they give him some pills he had on his pocket, not knowing that it was some rat poison that he was planning to sneak into their food.
- In The Hitchhiker (The Asylum's Mockbuster of the 2007 remake of The Hitcher), the title character befriends four road-tripping party girls who pick him up, then imprisons them in a hotel room and tortures them.

- In S.E. Hinton's Tex the titular character saves his older brother's life when a hitchhiker pulls a gun on them.
- In Larry Niven's story "The Deadlier Weapon", a hitchhiker pulls a knife on the driver who picked him up. The driver starts acting like he intends to kill them both by deliberately crashing the car, ramping up the psychological pressure by looking at the hitchhiker instead of the road until the hitchhiker gives up, drops the knife out the window, and allows himself to be dropped off in the median of a busy highway where he is trapped until the cops come for him.
- CHiPs once had a trio of Valley girls who would hitch rides from strangers, hold them hostage with a water pistol, and rob them. Their crime spree ends when they try this on someone who recognizes the water pistol for what it is and threatens to commit sexual assault on them. Luckily, the officers intervene before anything happens.
- One episode of Criminal Minds ("Safe Haven") features a teenage sociopath called Jeremy, who is hitchhiking his way back to his home (after his mother dumped him on another state exploiting the titular child protection law, knowing pretty well that he's a monster and deciding to let the government deal with him) and exploiting his innocent looks to be allowed to spend the night on the houses of the people who pick him up... where he goes on to annihilate them and their entire families.
- Six Feet Under had a very controversial episode, "That's My Dog", that almost approached Torture Porn, in which David Fisher was kidnapped, sexually assaulted, and almost murdered by a psycho hitch-hiker.

- In an episode of Futurama, the crew goes on a team-building trip with an overly enthusiastic coordinator. He says that just to make a point he'll pick up a random hitchhiker to catch him on the first trust fall of the trip. He picks up a very bored-looking hitchhiker and starts to fall back...only for the hitchhiker's stomach to open up into a mouth and eat him. Subverted because the hitchhiker turns out to have been placed there as part of the team-building exercise, and no one was actually eaten.
- In the Sonic Boom episode, "Planes, Trains, and Dude-Mobiles", during Sonic, Tails, and Knuckles' road trip to their Dude-itude concert, Knuckles picks up the Bike Chain Bandit, figuring he needed company while he drove the Dude-Mobile and Sonic and Tails were sleeping. A radio broadcast describes the Bike Chain Bandit as a large, snaggle-toothed opossum wearing a trenchcoat, and carrying a duffle bag filled with bicycle chains. The Bike Chain Bandit attempts to choke Knuckles with a bicycle chain while he is still driving, but is kicked out of the Dude-Mobile by Sonic. Near the end of the episode, Sonic, Tails, and Knuckles help a police officer who had earlier arrested them capture and arrest the Bike Chain Bandit.
- In an article about the decline in Real Life hitchhiking (caused largely by fear of this trope), Molly Osberg tells about a driver who, being in a bad headspace after a divorce, picked up two hitchhikers in the hope that they'd kill him. Osberg concludes that, nowadays, "picking up a hitcher can be considered a lackadaisical attempt at suicide."
- The murder of Phillip Fraser.
Harmful To Hitchhikers:
- Pee-wee's Big Adventure subverts this. Early on in his journey, Pee Wee hitches a ride with Mickey, who is quickly established as an escaped convict. However, he never harms Pee Wee and even lets him drive. When Pee Wee crashes the car and almost kills them, he still doesn't kill him but instead forces him to find new transportation.
- The opening and closing scenes of Joy Ride 2: Dead Ahead showcase that this is one of Rusty Nail's methods to obtain victims.

- Strange Frequency: One episode/story ("My Generation") features both forms: Wheeler (a driver Serial Killer that kills hitchhikers) and Walker (a Hostile Hitchhiker played straight). They focus on music (Grunge Rock for Wheeler and old-school Rock and Roll for Walker — if someone likes those genres, they are immediate targets), trying to kill each other and, when they wreck the car they are in, doing casual conversation on their killing methods as an old man that was passing by with his RV helps them fix the car... and soon after going on the road and thinking of teaming up, the car's brakes malfunction and they crash fatally. Turns out that the old man is a third Serial Killer, one that has a modus operandi of sabotaging vehicles... if you don't like Big-Band music.
- Masters of Horror featured an episode, "Pick Me Up", where Wheeler is a truck driver who kills hitchers that he picks up, and Walker is a hitchhiker who kills people that pick him up. The third serial killer in this scenario is a pair of ambulance drivers.

- Halfway through the miniseries The Deliberate Stranger, Ted Bundy picks up a pretty girl hitchhiking. Given that by this point in the film, Bundy has been well established as a misogynistic Serial Killer, it's safe to say he has nefarious intentions.
- Unsolved Mysteries again. Two college kids entered a rest stop and called the police, having just learned that the guy they were riding with had stolen the truck he was driving. While he never explicitly threatened them, they were clearly fearful that he had done something to the trucks owner and refused to ride with him anymore. Given that the man had indeed murdered the truck's owner, their instincts probably saved their lives.
- Rides With Strangers was created based on this trope; the player has to hitchhike their way to a meeting they are late for, and must avoid being killed by the driver.
- A Grand Theft Auto V player can do this while playing as Trevor. If he encounters someone lost in the wild, he can deliver them to the Altruist cult to be eaten.
- RWBY Chibi: Episode One of Season 3 has Cinder driving around picking up people for "nefarious reasons" (and being pretty Obviously Evil about her intentions once she stops by them). Having already done so several times already, she picks up Jaune and Ren, who save themselves by means of Jaune invoking the Most Annoying Sound (singing the opening theme of Camp Camp until she can't take it).
- On September 15, 1978, 15-year old Mary Vincent was hitchhiking through Berkeley, California when she was picked up by Lawrence Singleton, who raped and sodomized her, then chopped off her arms and flung her, naked and bleeding into a ditch. Amazingly, she survived.
- In a story that straddles this and the harmful hitchhiker variant, Paul Teodo told a story at The Moth about a time he was hitchhiking and picked up by John Wayne Gacy. Paul was a violently unstable young man at the time and believes he survived the encounter because of his own violent attitude.
