Run a Manual Test for CARB Clean Truck Check Follow

CARB Clean Truck Check (CARB CTC) tests run automatically during the vehicle’s scheduled testing window. If the vehicle does not have a valid test result in the previous testing window, you can run a manual test.

Follow these steps to run a manual test:

1. Log in to portal.hos247.com.

2. In the left-hand menu, click CARB CTC.

3. Find the vehicle and click Run Manual Test in the Previous Test Status column.

   

4. In the confirmation window, click Run Manual Test.

   

The Previous Test Status changes to Running (On-Demand) while the test is in progress. When it finishes, the status shows one of two results:

• Passed: CARB accepted the test result.

• Failed: CARB did not accept the test result. Fix the vehicle issue, then click Retry to run the test again.
