If you’ve hauled into California lately, you’ve probably heard some chatter at the yard, on the CB, or in a group chat:
“Didn’t the EPA shut down CARB’s Clean Truck Check thing?”
“So… do out-of-state trucks still have to do this smog test or not?”
Short answer: the rules are messy, the headlines are confusing, and getting this wrong can cost you real money.
Let’s break it down in plain English — no legal mumbo jumbo, no government alphabet soup.
California (through CARB) rolled out the Clean Truck Check program to crack down on dirty diesel emissions. The goal? Cleaner air. The result? A whole lot of paperwork and headaches for truckers.
The idea was simple:
If your truck runs in California, you’re expected to:
Then the EPA stepped in and basically said:
“Hold up — California can’t force out-of-state trucks to follow a state inspection program.”
Cue the internet losing its mind.
Here’s where people get tripped up:
Even though the EPA pushed back, CARB didn’t pack it up and go home. California is still running the Clean Truck Check program and still expects trucks operating in the state to play by the rules.
So yeah… welcome to regulatory whiplash.
Let’s skip the politics and talk about reality:
If your truck touches California asphalt, you’re still on CARB’s radar.
That means:
Even worse?
If you’re non-compliant, it can lead to:
– Delayed loads
– Turned-away freight
– Brokers choosing someone else
– Terminal or port access issues
– Costly penalties
You might win an argument on Facebook about who’s “right” — but CARB enforcement doesn’t care about comment sections.
Dispatchers and brokers aren’t just pushing paper — they’re protecting revenue.
If a truck gets flagged for CARB non-compliance:
More and more brokers are asking:
“Are you CARB compliant?”
Before they even tender the load.
If your answer is “uhh… I think so?” — that’s not exactly confidence-inspiring.
Here’s the no-drama strategy:
✔️ Register your truck in CARB’s system
✔️ Stay current on Clean Truck Check testing
✔️ Fix small issues before they become big problems
✔️ Keep proof of compliance handy
Is it annoying? Sure.
Is it cheaper than losing a load, getting fined, or sitting out a day of work?
Absolutely.
