CLEAN TRUCK CHECK AUTHORITY
Clean Truck Check in Orange County.
Choose mobile testing at your vehicle's location or an OBD test at our Huntington Beach facility. Start with the service you need, then choose the appointment option that fits your day.
Two ways to get your testing done.
Visit Huntington Beach
Walk-in OBD testing is available at Clean Truck Check Authority, 16861 Beach Blvd, Huntington Beach, CA 92647.
Check current hours and call about access before bringing a large or specialty vehicle. For opacity or alternative-fuel inspection questions, call first to arrange the appropriate service.
Arrange mobile testing
Request a visit to your yard or another suitable location in our Orange County service area. Share the address and when the vehicle will be available.
Include a contact who can provide vehicle access. The team will confirm the requested location and scheduling; a mobile inquiry is not yet a confirmed appointment.
Match the appointment to the engine.
Your fuel type and engine model year help determine the correct test. An engine replacement can change which inspection you need, so use the engine information rather than only the year on the registration.
Read OBD testing and pricing, smoke opacity and visual inspection, or the test selection guide. Tell the team about a check-engine light, recent repairs or a battery disconnection before the visit.
Several vehicles at one Orange County location?
A fleet request lets us review the vehicle mix and availability together. Send the vehicle count, engine details, location and individual CTC-VIS deadlines. Do not assume one test method fits every truck.
Ask the team to confirm fleet-pricing conditions before scheduling. An individual walk-in and a coordinated multi-vehicle mobile appointment are different arrangements.
Need help with the account, not just the test?
A reporting issue or account question may need a separate CTC-VIS support request. Explain what you see in the vehicle record, but do not send your account password or payment-card details through the contact form.
Explore CTC-VIS support or read the common questions.
Pick your next step.
Book a test or ask about a walk-in or mobile visit.
Interested in an automated option for compatible vehicles? CTCA is an authorized seller of ASAH Vehicle Gateway. A device purchase is not required for testing.
