CARB Clean Truck Check Information by the Numbers
The 2025 CARB Clean Truck Check
A visual guide to understanding the new regulations, the costs of non-compliance, and the path to staying on the road.
Over one million heavy-duty vehicles operating in California fall under the new regulation.
Fines for non-compliance can exceed $800 per day, with holds placed on DMV registration.
Fleets must submit passing tests multiple times per year to remain compliant, starting in 2025.
The High Cost of Compliance Hassle
Beyond fines, the biggest cost is operational downtime. Taking a truck to a fixed testing station means pulling a driver off a route, fighting traffic, and waiting in line.
Typical Downtime per Test (4-Hour Total)
Wasted Hours Add Up.
For every truck, a single test can burn half a day. For a fleet of 10 trucks needing 4 tests a year, that's **160 hours** of lost productivity.
- Driver Pay: $100+ in wages for sitting in traffic.
- Lost Revenue: A missed load or delayed delivery.
- Admin Time: Hours spent coordinating logistics and drivers.
The 3-Step Compliance Timeline
Staying compliant involves more than just a test. Fleets must follow this simple process for every truck they operate.
Register in CTC-VIS
All vehicles must be registered in the CARB Clean Truck Check (CTC-VIS) database and annual compliance fees must be paid.
Identify Your Test
Determine your testing requirement: 2013+ model year engines require an OBD test. 2012 and older engines require a J1667 Smoke Opacity Test.
Submit Passing Tests
Submit passing tests 2-4 times per year based on your compliance schedule. A failed test or missed deadline results in non-compliance.
