In December 2021, the California Air Resources Board (CARB) approved the Heavy-Duty Inspection and Maintenance (HD I/M) Program, now known as Clean Truck Check, in an ongoing effort to meet air quality standards by ensuring heavy-duty vehicle emissions control systems operate properly throughout the life of the vehicle. The program requirements include reporting in the Clean Truck Check database (CleanTruckCheck.arb.ca.gov), paying annual per vehicle compliance fee ($30), and submitting periodic testing results.

​

Periodic vehicle testing requirements become effective January 1st, 2024. This requirement means that a passing compliance test would need to be submitted to CARB within 90 days prior to a vehicle’s compliance deadline. For example, if a vehicle has a compliance deadline on July 1, 2024, a passing compliance test would need to be submitted between April 2, 2024, and July 1, 2024.

Based on the projected timing of the periodic testing requirements, most vehicles would be required to undergo one periodic compliance test in 2024. Starting in calendar year 2025, most vehicles would then be subject to the standard twice per year periodic testing requirements.

​

Only a credentialed tester who is authorized to submit test results to California Air Resources Board (CARB) in accordance with the requirements of the Clean Truck Check (HD I/M) regulation can perform compliance testing.
