Common Questions

What trucks are required to get carb compliance testing in California?

carb’s Clean Truck Check program applies to nearly all diesel and alternative fuel heavy-duty vehicles with a gross vehicle weight rating over 14,000 pounds that operate on California public roads.

Most heavy-duty trucks are required to undergo emissions compliance testing twice per year under California’s Clean Truck Check program. For California-registered vehicles, your compliance deadlines are tied to your DMV registration expiration date.

If your truck fails the emissions test, you’ll receive a detailed report explaining why. Common reasons include fault codes in the emissions control system, the check engine light being on, or OBD readiness monitors not being set.
