Eligibility
Vehicles Subject to Clean Truck Check
Clean Truck Check applies to diesel and alternative-fuel vehicles over 14,000 lbs GVWR operating on California roads, including both in-state and out-of-state fleets. Requirements may vary based on the vehicle’s registration, classification, and use. This includes diesel, diesel-hybrid, natural gas, and other alternative-fuel vehicles.
Eligible Vehicle Types
14,000+ lbs
Gross Vehicle Weight RatingDiesel and alternative fuel vehicles with a Gross Vehicle Weight Rating (GVWR) over 14,000 pounds.
- Commercial trucks and buses
- Transit and school buses
- Motorcoaches
- California-registered motorhomes
- Agricultural vehicles
- Heavy-duty hybrid vehicles
- Box trucks
- Single-vehicle operations and fleets
- Refrigerator trucks
Out-of-State Vehicles
Covered out-of-state vehicles must also meet Clean Truck Check requirements when operating on California public roads. Out-of-state registration alone does not provide an exemption. However, noncommercial motorhomes registered outside California are excluded from the program.
Ongoing Renewal
All vehicles subject to the Clean Truck Check must maintain ongoing CARB compliance through regular renewal. Heavy-duty commercial vehicles over 14,000 lbs GVWR complete compliance checks semi-annually, while motorhomes and agricultural vehicles renew annually. Keeping records up to date ensures the vehicle remains compliant and legally operable in California.
Requirements
What Are the Requirements to Obtain the Clean Truck Check Certificate?
To qualify for the Clean Truck Check certificate, vehicles must meet specific requirements related to weight, fuel type, testing, and registration.
Compliance Checklist
Gross Vehicle Weight Rating (GVWR)
Applies to vehicles with a GVWR over 14,000 pounds, which includes the vehicle’s empty weight and maximum load capacity.
Fuel Type
Applies to vehicles powered by diesel, a diesel hybrid, natural gas, or another alternative fuel — regardless of engine model year. Battery-electric and hydrogen fuel-cell vehicles are not covered by the program.
Testing Frequency
Semi-Annual Testing: most heavy-duty vehicles are tested twice per year.
Annual Testing: motorhomes and agricultural vehicles are tested once per year.
Quarterly Testing (starting October 2027): vehicles with on-board diagnostics (OBD) will transition to quarterly testing for stricter emissions monitoring.
Emissions Standards
Vehicles must meet or exceed CARB’s emissions thresholds for pollutants like particulate matter (PM) and nitrogen oxides (NOx) during testing.
Registration
All vehicles must be registered in the Clean Truck Check Vehicle Inspection System (CTC-VIS).
Registration requires the following details:
- Vehicle Identification Number (VIN)
- License plate number
- GVWR
- State and country of registration
Annual Compliance Fee
An annual fee must be paid for each vehicle to participate in the program.

Frequently Asked Questions
What does California-CARB.com do?
We submit Clean Truck Check vehicle information and related requests through CTC-VIS. Our service covers reporting only; we do not conduct inspections or emissions tests.
Do you perform Clean Truck Check emissions testing?
No. A CARB-credentialed tester must perform the emissions test and submit the result. The tester's fee is separate from our reporting fee.
Do you issue the Clean Truck Check compliance certificate?
Official certificates are issued directly by CARB once all program steps are met. We handle the heavy lifting for you filing your reporting in CTC-VIS, tracking your vehicle's status, and sending over your official state confirmation as soon as CARB clears your account.
What happens after I submit my application?
You receive a payment receipt immediately. Our team then submits the reporting in CTC-VIS and emails the registration confirmation, reported status, and any next steps that apply.
Does a 5-day pass make my vehicle compliant?
The 5-Day Pass provides temporary travel permission for five consecutive days but it is not full compliance. It does not clear a DMV registration hold or resolve a non-compliant status in CTC-VIS. Permanent compliance still requires complete database reporting, fee payments, and emissions testing.
Can you add another truck to my CTC-VIS account?
Yes. We can report an additional eligible vehicle under an existing account using the information supplied in the application.
