CARB Compliance in California

What CARB compliance means for fleets

California Air Resources Board compliance is more than a one-time inspection. Fleet operators need a repeatable process for testing, documentation, and deadline tracking. The Clean Truck Check program relies on accurate test results, timely submissions, and proactive maintenance when vehicles trigger emissions-related issues.

Official program details are published by CARB. Always confirm current fees, due dates, and eligibility on arb.ca.gov and in your CTC-VIS account.
