O TruckingWeigh Station CB Slang: Complete Dictionary (2026)
Key Takeaways
- "Chicken coop" and "coop" both mean a weigh station; "coop is open" means pull in, "coop is closed" means keep rolling.
- A "coop card" is a bypass transponder like PrePass or Drivewyze; a green light lets you legally skip an open coop, a red light means you must weigh.
- A "portable parking lot" is a temporary or portable scale and is not covered by any bypass network, so a green light won't help there.
- "Scale jockey" is the weigh-station officer and "heavyweight" is an overweight truck.
- Coop status reports on channel 19 stay useful in 2026 because no app shows real-time staffing or what officers are checking right now.

How a Coop Report Sounds on the CB
Most weigh-station chatter is short and to the point. Here is a typical exchange you will hear on channel 19 as you approach a scale:
Westbound driver: “Hey westbound, what's the chicken coop doing up at the 142?”
Eastbound driver: “Coop's open and they're checking everything — pull-around line's about ten deep.”
Westbound driver: “Appreciate it, got my coop card so I'll see if I get the green light. Keep the shiny side up.”
In a few seconds the second driver passed along three useful facts: the coop is staffed, officers are doing full inspections (not just weight), and there is a backup. That is exactly the kind of report that helps everyone plan — whether to slow down, get fuel first, or make sure their paperwork and logs are squared away before the pull-in.
Why Coop Reports Still Matter in 2026
Bypass transponders and weigh-in-motion (WIM) sensors have changed how scales operate, but they have not made the CB report obsolete. No app reliably tells you whether a station is staffed and what officers are focusing on at this exact moment, and a few categories of stops are not covered by any bypass network at all:
- Portable / temporary scales. A “portable parking lot” set up at a rest area or shoulder is not part of PrePass or Drivewyze, so a green light won't help you there.
- Red-light pulls. Even with a coop card, a red light means you must weigh, so knowing the coop is open lets you get in the right lane early.
- Full inspections. “Checking everything” is a heads-up to verify your weigh-station readiness — lights, straps, and logs — before you roll in.
- Weight surprises. If you are running close to the line, a coop report buys time to consider a CAT scale check before the official scale flags you as a “heavyweight.”

Weigh Station Slang FAQ
Common questions about weigh station CB slang
What is a chicken coop in trucker slang?
Chicken coop (or just 'coop') is CB radio slang for a weigh station. When truckers say 'the coop is open,' they mean the weigh station ahead is operational and trucks must pull in. 'Coop is closed' means the station is shut down. The term likely comes from trucks lined up to enter a station looking like chickens filing into a coop.
What does 'portable parking lot' mean in CB slang?
A portable parking lot is CB slang for a temporary or portable weigh station. These are enforcement operations set up at rest areas, truck stops, or highway shoulders using portable scales. They are harder to predict than permanent weigh stations and are not covered by bypass services like PrePass or Drivewyze.
What is a 'scale jockey' in trucking?
Scale jockey is trucker slang for a weigh station officer — the person operating the scale and checking trucks at the weigh station. The term is generally neutral, not derogatory. It simply identifies the officer by their role at the scale.
What does 'coop card' mean?
Coop card is CB slang for a weigh station bypass transponder, such as PrePass. When a trucker asks 'got your coop card?', they are asking if you have a bypass device that might let you skip the weigh station. Having a 'coop card' with a green light means you can bypass the station without stopping.
Is chicken coop slang still used in 2026?
Yes. Even though CB chatter is lighter than it was decades ago, 'chicken coop' and 'coop is open/closed' are still common on channel 19, especially on busy interstate corridors. Coop status reports remain one of the most useful and frequent CB calls because no app shows real-time staffing of every scale. New drivers should know the term regardless of how much they personally use the radio.
Do I still have to stop if I have PrePass or Drivewyze?
Not always. A bypass transponder (your 'coop card') uses your safety record and weight history to issue a green light, which lets you legally roll past an open coop without pulling in. A red light means you must enter and weigh. Bypass is never guaranteed on any given pass, and portable or temporary scales are not part of the bypass networks, so you still have to stop for those.
What is weigh-in-motion (WIM) and is it CB slang?
Weigh-in-motion is a real enforcement technology, not slang. WIM sensors embedded in the pavement weigh your truck at highway speed before the scale, so officers can flag overweight or suspicious trucks to pull in while waving others through. On the CB you might hear it called 'the mainline scale' or 'getting weighed on the fly.' It is one reason a coop can process trucks quickly even when it is open.
