Emissions compliance testing becomes mandatory. All covered vehicles must pass inspection to operate legally in California.
Semi-Annual Testing Begins
Semi-annual testing deadlines begin; compliance fees of $31.18/vehicle. Testing frequency increases to twice per year.

Full enforcement; compliance fee rises to $32.13; no tolerance for missed deadlines. Non-compliant vehicles face immediate penalties, registration holds, and may be barred from operating.

Customer Reviews
Trusted by owner-operators and fleet managers across California
"Julero completely changed how we handle fleet compliance. They came directly to our yard, inspected all 24 trucks in an afternoon, and had the certificates ready on the spot. It saved us thousands in potential downtime."
"As an owner-operator, I was worried about the new CARB requirements. Julero explained everything in Spanish, made it easy to understand, and got me compliant the same day."

CARB Compliance Questions
The Clean Truck Check (CTC) program is a California Air Resources Board (CARB) initiative requiring periodic emissions inspections for heavy-duty diesel vehicles. It replaced the old Periodic Smoke Inspection Program (PSIP) and Roadside Heavy-Duty Vehicle Inspection Program (RHDI) to ensure trucks operating in California meet modern emissions standards.
Heavy-duty diesel vehicles with a Gross Vehicle Weight Rating (GVWR) of 14,001 lbs or more that operate in California are required to pass CTC inspections. This includes both in-state and out-of-state trucks that travel through California.
Inspection frequency depends on your vehicle type and the current program phase. As of January 2025, most covered vehicles require semi-annual testing (twice per year). Starting October 2027, all OBD-equipped vehicles will need quarterly testing (four times per year). Your specific deadline is tied to your vehicle registration or fleet compliance schedule with CARB. We'll help you determine your exact dates and send reminders before each testing window.
If your truck fails, we'll provide a detailed report of what needs to be fixed. We can connect you with trusted repair shops in our network that specialize in emissions system repairs. After repairs, you'll need to schedule a re-inspection to verify compliance.
