View CARB Clean Truck Check Testing Results Follow

The CARB CTC page shows emissions test results for every vehicle with CARB Clean Truck Check enabled.

To view this information:

1. Log in to portal.hos247.com.

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

Each row is one vehicle. For each vehicle, the page shows its last testing period and its next scheduled one, including the date range when tests can run and the test’s status.

The main results are:

• Passed: CARB accepted the test result. It remains valid until the next testing deadline.

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

• Missing: The testing window closed without a test, usually because the engine was not running. Run a new test while the engine is running.

Failed and Missing results need action before the testing deadline. Other statuses show where a test stands, such as scheduled or in progress.

Marking a previous testing window as passed records the result in the portal only. It is not submitted to CARB.
