A Friendly Glossary of Trucker Slang for Spouses and New Drivers

Why Truckers Talk Like That

When the person you love starts driving a truck for a living, the phone calls home start sounding like they are coming from another planet. Words fly out of the speaker that make you wonder whether you are talking to a trucker or receiving a transmission from a satellite.

Trucker slang did not come from nowhere. It grew out of CB radio culture in the 1970s, when drivers needed a way to warn each other about traffic, weather, and — naturally — speed traps. The language stuck. Today, drivers still sprinkle it into conversation the way a fisherman talks about tides. It is shorthand for a life spent moving freight down the highway.

This glossary is for the spouses, partners, kids, and new drivers who keep hearing these words and nodding along while secretly reaching for a dictionary. No judgment. We have all been there.

The Glossary

Bear — A police officer, usually a highway patrol trooper. If your driver says, “There is a bear in the woods,” they do not mean a wildlife encounter is imminent. They mean a patrol car is sitting somewhere partly hidden, probably running radar. A “full-grown bear” is a state trooper. A “bear cave” is a police station or a spot where patrol cars tend to gather.

Chicken coop — A weigh station. These are the fenced-in areas along the highway where trucks pull in to be checked. When your driver says they had to “run the coop,” they mean they went through a weigh station. If the coops are “closed,” the driver gets to keep rolling without stopping.

Come-a-part — A breakdown, or a truck that seems to be held together with duct tape and prayers. “She is come-a-parting again” means something mechanical is misbehaving.

Deadhead — Driving the truck with an empty trailer. The driver is still on the road, still burning fuel, but not hauling paying freight. It is the part of the job that pays the bills the least.

Driver — A term truckers use to address each other, like “buddy” or “pal.” If a stranger on the radio says, “Hey, driver,” they are talking to whoever is listening. It is friendly, not weird.

Good buddy — Another friendly form of address between drivers. It is the CB equivalent of waving to a neighbor across the fence. Use it with warmth.

Lot lizard — A person who wanders truck stop parking lots at night offering unwanted company. Drivers are not fond of them. If your driver mentions a lot lizard, they are not talking about a pet reptile. They are talking about someone knocking on the truck door at two in the morning.

Motor mouth — Someone on the CB radio who will not stop talking. Every channel has one. They mean well.

Parking lot — A highway that is so backed up with traffic that it might as well be a parking lot. When your driver says they are stuck in a parking lot on I-95, expect a late dinner.

Plain wrapper — An unmarked police car. It looks like a regular sedan but has lights hidden behind the grille. Drivers warn each other when they spot one.

Revenue collector — A police officer running radar, usually in a spot where the speed limit drops suddenly. The joke is that the ticket money funds the local budget. Whether that is true or not, drivers sure believe it.

Smokey — Another word for a police officer, borrowed from the cartoon campaign hat that highway patrol troopers wear. “Smokey is taking pictures” means a patrol car is running radar.

Truck stop — A large fuel and rest stop designed for commercial trucks. These are not the same as regular gas stations. They have diesel pumps wide enough for a fifty-three-foot trailer, showers you can rent by the minute, and coffee that has been on the burner since dawn.

Twenty (as in “What is your twenty?”) — Location. It comes from the old ten-code system, where 10-20 meant location. When your driver asks for your twenty, they want to know where you are.

Yard — The terminal or lot where trucks are parked, loaded, unloaded, and maintained. “I am sitting in the yard” means your driver is at a company facility, probably waiting on something.

A Few That Sound Rude But Are Not

Alligator — A blown-out tire in the road, the kind that sheds chunks of rubber. Drivers call the debris alligators because of how they look sprawled across the lane. Nobody wants to hit one.

Donkey — A truck's auxiliary power unit, the small engine that runs the heater and air conditioner without idling the big engine. It saves fuel and keeps the driver comfortable during mandatory rest.

Turtle — A slow-moving vehicle, usually in the left lane. Nobody wants to be the turtle.

The Heart Behind the Slang

Behind every strange word is a person trying to stay safe, stay awake, and stay connected to the community of drivers who understand what the road is really like. When your driver calls home and says, “I dodged two alligators and a bear today,” they are not telling you about a wildlife safari. They are telling you they are okay, the truck is running, and they will see you soon.

Listen for the love underneath the lingo. It is always there.
