CTC VIS Portal
The CTC VIS Portal (Clean Truck Check Vehicle Inspection System) is the official online system developed by the California Air Resources Board (CARB) to manage and report Clean Truck Check compliance. If your vehicle is subject to CARB’s emissions testing regulations, the portal is where you register, submit test results, and stay updated on your compliance status.
Whether you’re a driver, fleet owner, broker, or dispatcher, the CTC VIS Portal is your central tool for meeting California’s clean air requirements.
What is the CTC VIS Portal and Who Uses It?
The CTC VIS Portal is an online platform provided by CARB to help vehicle owners and fleet managers comply with the Clean Truck Check Program. This system is required for all owners of diesel and alternative-fuel heavy-duty vehicles with a Gross Vehicle Weight Rating (GVWR) over 14,000 lbs that operate in California — even if they are registered out of state.
Once registered in the portal, users can manage vehicle profiles, schedule and submit OBD (On-Board Diagnostics) test results, and receive compliance notifications. The system helps CARB track emissions testing and verify that vehicles are being properly maintained and inspected according to state regulations.
Users include:
Individual truck owners
Fleet operators
Brokers and dispatchers
Mechanics and test providers
Compliance managers for logistics companies
By centralizing all Clean Truck Check activity in one secure system, the CTC-VIS Portal makes it easier to avoid penalties, track deadlines, and stay compliant.
The Importance of Staying Active on CTC VIS
Staying active on the CTC-VIS Portal isn’t just a technical task it’s a vital part of protecting your business and keeping your operations legal in California. CARB uses this platform to enforce compliance, issue reminders, and manage vehicle data for thousands of trucks that enter the state daily.
Failing to update your vehicle’s information, skipping a test cycle, or allowing a vehicle to show up as “out of compliance” can lead to real-world consequences including fines, DMV registration denial, and even being flagged at roadside inspections.
By staying on top of portal tasks and using certified testers to submit your data, you avoid these risks entirely. Our team at Ramirez Mobile Clean Truck Check Services works with clients every day to ensure all CTC-VIS submissions are made correctly and on time.
We also recommend assigning a specific person whether it’s you, your dispatcher, or a compliance manager to routinely log in and check the portal for any alerts or updates. This is especially important for brokers and fleet managers handling multiple vehicles, as one missed test can affect the whole operation.
In short, CTC-VIS is your direct line to CARB compliance. Use it wisely, and your trucks will stay on the road clean, legal, and ready for business.
