In chase scenes, there comes a time when the trailer of a Mack blocks the driver's path. And, there isn't time to avoid a collision. What does one do?
If the car is low enough and/or the trailer high enough, most of the car will pass under it safely. Except for the roof and windows. The car is perfectly drivable afterward. The driver may even remark, "I've always wanted a convertible." Hence, the name of the trope.
Sometimes, if the car's low enough, it might just fit Under the Truck.
- In Soul Eater Giriko complains the limousine Arachne's Butler arranged to pick them up with after she was resurrected was too cramped and invoked this trope while it was still stationary. Being an Ax-Crazy guy with the ability to turn into a chainsaw does that.
- In Durarara!!, Shizuo pulls this off on Horada's car by slicing the top off with a highway sign.
- Episode 6 (second half) of Panty & Stocking with Garterbelt has this happen to See-Through by another vehicle. Chuck didn't duck of course.
- Le Gendarme de Saint-Tropez: One of the earliest known examples on film was done by Sister Clotilde with a wooden barrier, during one of her Drives Like Crazy moments. It's only part of the complete trashing she proceeds to inflict on her poor 2CV.
- Happens to an Opel Admiral driven by a henchman through a crossing bar, during the chase scene in 1972's The Master Touch.
- James Bond
- The long chase scene in The Seven-Ups ends with one of these. Only the front half of Roy Scheider's car gets sliced off, though.
- In The Toxic Avenger Part II, during the final chase scene Toxi's cab driver is unable to avoid this fate. After a moment of silence, everyone in the cab freaks out and when the driver starts ranting about how his cab's been ruined, Toxi tells him to chill out 'cause he now has a convertible and hands him a pair of sunglasses (and he does!). Oddly enough, the little Jesus statue in the back is unharmed.
- In The Mummy Returns they do this to the second floor of a double-decker bus.
- Happens to a police car in the live-action Disney comedy No Deposit, No Return.

- Averted in A Clockwork Orange. They're already in a convertible, and it suffers no damage whatsoever when it goes under a truck.

- In the 1987 film Cyclone the scene is shown four times in rapid succession. Watch here.
- The 1996 movie TheSweeper has this when Mark drives under the trailer of a gasoline tanker, prompting an obvious "convertible" remark from him after driving under it.
- Averted in Red 2 when the protagonists are driving a Lotus Exige S with such a low profile they can literally drive sideways under a truck, coming out behind the vehicle that's chasing them.
- A particularly comedic example occurs in The Naked Gun when the car in question broadsides into a tanker truck, provoking a large explosion. When it emerges from the other side of the conflagration, the top of the burning vehicle is indeed sheared off, and the unfortunate driver is sprawled on the hood, still holding the severed steering wheel. Things only get worse for him after that.
- In Sonic the Hedgehog (2020), during the highway chase, a tiny Robotnik drone cuts off the top of Tom's truck with a laser cutter.
Sonic: Aww, this one is cute. Let's keep him! [tiny robot activates its laser cutter, and begins burning its way around the top of the car] WHOA!Tom: OH, COME ON!Sonic: How can something so adorable be so terrible?! ...You've got car insurance, right?
- Alarm für Cobra 11: At the beginning of the "Die Braut" episode, a drowsy driver crashes his truck in front of Semir's car and he is unable to stop before the impact of the trailer rips off the roof.

- The Double-Decker Bus vs Low Bridge variant happens frequently in Britain.
- The Norfolk SouthernGregson Street Overpass in Durham, North Carolina. This is a railroad bridge you're more likely to know of by its alternate nickname, the 11 foot 8 Bridge, owing to its low vertical clearance of 11 feet 8 inches (3.56 m) It cannot be raised, because nearby grade crossings would also have to be raised, and the street cannot be lowered, because a major sewer line runs right under the street. Despite numerous big yellow warning signs and warning lights, there's always at least one overheight truck per month that ends up getting its roof sheared off in spectacular fashion. Jürgen Henn, who runs a nearby office, mounted two video cameras to record the crashes and post every instance of this to YouTube. The frequency of overheight trucks trying to go under the bridge much so that the locals have nicknamed it the "Can Opener Bridge" and gained it international attention. There is even a website dedicated to hosting the videos of these crashes, guaranteeing that these unlucky drivers will never forget. Near the end of 2019, they were finally able to raise it eight inches... and overheight trucks still continue to lose chunks of roof to it.
- While a teenager, future actor Richard Harris was delivering a massive haulage truck to Dublin. Being somewhat drunk, he tried to drive under a low bridge in the belief that he could get through if he drove quickly enough.

- In April 2018, a truck carrying a Range Rover Velar was passing under a bridge when the Velar's roof was ripped off. News sources jokingly stated that the truck driver accidentally created the Range Rover Velar Convertible.
- Austrian Heinz Meixner smuggled his German bride Margarete Thurau (along with her mother) from East Berlin that way. He modified the rented car so that its windshield (the car was a convertible already) would easily detach, and let some air from the tires to make the car even lower. Then he simply drove under the checkpoint bar. Although, according to some accounts, he did remove the windshield himself just before it would collide with the bar by punching it. After this trick was repeated by some other escapees, East Germans modified their checkpoints, adding vertical bars under the checkpoint bar and making the path after the checkpoint zigzagged.
