By the AIRLIMITS Compliance Team
Headquartered in Long Beach, California
If you are searching for Clean Truck Check in Long Beach, you have reached the actual AIRLIMITS team: not a directory that forwards your request to an unknown provider.
AIRLIMITS is headquartered in downtown Long Beach and helps truck owners, fleet managers, drayage carriers, contractors, and other commercial operators determine the correct Clean Truck Check requirement. Our downtown headquarters is not a drive-in shop or truck service yard for heavy-duty vehicles. Instead, we provide mobile CARB testing in Long Beach by bringing credentialed testing directly to the customer’s location for vehicles that require an in-person inspection, and we offer AIRPASS™ automated testing for eligible OBD-equipped vehicles.
This approach is designed for both local fleets and nationwide truck drivers operating in the region. Rather than expecting drivers to bring their trucks to our downtown office, AIRLIMITS comes to the truck when mobile testing is required.
The Quick Answer
AIRLIMITS provides mobile Clean Truck Check testing in Long Beach by appointment, subject to technician availability, vehicle requirements, and safe site access. Our headquarters is located in downtown Long Beach, but testing is performed at the customer’s approved location rather than at our office.
Depending on the vehicle, mobile service may include:
- OBD emissions testing
- Smoke opacity testing
- Visual emissions-control-equipment inspection
- Post-repair retesting
- Notice to Submit testing
- Coordinated fleet-testing events
Eligible OBD-equipped vehicles may also qualify for AIRPASS. The plug-and-go device connects to the truck’s diagnostic port, works through AIRLINK™, and automatically submits testing results to CARB when the vehicle is ready.
The correct option depends on the engine model year, fuel type, diagnostic system, compliance deadline, and test result history.
Important: Mobile testing requires a confirmed appointment. The testing location must be safe, accessible, and approved in advance. Port terminals and secured facilities may have additional access rules.
Why Clean Truck Check Matters in Long Beach
The Port of Long Beach is one of the busiest freight gateways in the United States. The port handles approximately 9 million or more twenty-foot-equivalent units (TEUs) annually and moves cargo valued at roughly $300 billion per year, according to port and industry reporting. See the Port of Long Beach for current port information and statistics.
That activity supports a large network of:
- Port and drayage carriers
- Owner-operators
- Warehouses and logistics companies
- Construction contractors
- Delivery and service fleets
- Refuse and environmental-service providers
- Buses and shuttle operators
- Out-of-state carriers entering California
Clean Truck Check is not limited to trucks registered in Long Beach or even to trucks registered in California. The program generally applies to qualifying diesel and alternative-fuel heavy-duty vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds when they operate on California public roads.
An out-of-state truck entering Long Beach for a port move, delivery, construction project, or service call may therefore have Clean Truck Check obligations even if its home terminal is in Nevada, Arizona, Texas, or another state.
What Is California Clean Truck Check?
Clean Truck Check: also called the Heavy-Duty Inspection and Maintenance (HD I/M) program: is California’s emissions inspection and maintenance program for qualifying heavy-duty vehicles.
It is separate from the passenger-vehicle Smog Check program. Although some operators refer to it as a heavy-duty smog check in Long Beach, Clean Truck Check has its own testing categories, reporting system, devices, and tester requirements.
Vehicle owners generally need to:
- Report the vehicle in the Clean Truck Check Vehicle Inspection System (CTC-VIS).
- Pay the required annual compliance fee.
- Submit a passing emissions test by the vehicle’s deadline.
- Resolve any outstanding enforcement action or registration issue.
A passing test is important, but it may not resolve an account problem if the annual fee, vehicle information, or another compliance requirement remains incomplete.
Which Test Does My Long Beach Truck Need?
CARB bases the testing method primarily on the engine model year, fuel type, and onboard diagnostic equipment. Always confirm the engine emissions control label and the due date shown in CTC-VIS.
2013-and-Newer Diesel Engines
These vehicles generally fall into the OBD-equipped category and require an on-board diagnostics (OBD) scan using a CARB-certified testing device.
An eligible truck may complete the test through:
- Mobile OBD testing by a credentialed technician
- Automated testing through AIRPASS
2012-and-Older Diesel Engines
These vehicles generally require both:
- A smoke opacity test using an SAE J1667-compatible smoke meter
- A visual inspection of emissions-control equipment
This is a hands-on inspection. AIRPASS is not the correct testing method for an older non-OBD diesel vehicle.
2018-and-Newer Alternative-Fuel Engines
Qualifying OBD-equipped alternative-fuel vehicles generally require an OBD scan using an approved testing device.
2017-and-Older Alternative-Fuel Engines
These vehicles generally require a visual emissions-control-equipment inspection but are not subject to the diesel smoke opacity portion.
Some off-road-engine configurations may also require opacity and visual testing regardless of engine model year. When the vehicle configuration is unusual, review the requirement before scheduling.
Option One: Mobile Clean Truck Check Testing in Long Beach
Mobile testing is usually the best choice when the vehicle requires opacity testing, a visual inspection, or immediate hands-on service.
AIRLIMITS can coordinate mobile truck emissions testing in Long Beach at a safe and accessible customer location. Although AIRLIMITS is headquartered in downtown Long Beach, our office is not set up as a drive-in testing bay or truck service yard. Instead, we dispatch mobile compliance support to the truck’s location when site conditions allow.
This matters for both Long Beach-area fleets and out-of-state or nationwide operators working in the region. If a truck is operating near the port, at a warehouse, on a jobsite, or at a fleet yard, the goal is to meet the vehicle where it is rather than direct the driver to our downtown headquarters.
Before confirming the appointment, we need to verify the vehicle and site details, including:
- VIN and license plate
- Engine model year and fuel type
- Vehicle location
- CTC-VIS deadline or Notice to Submit
- Available working space
- Site access and security requirements
- Whether the truck needs a post-repair retest
A mobile appointment can reduce unnecessary travel and help keep the truck at its normal operating location. However, technicians cannot automatically enter every port terminal, private yard, or secured facility. Port of Long Beach access must be coordinated in advance.

Option Two: Automated Testing With AIRPASS
For an eligible OBD-equipped truck, AIRPASS can reduce the need to schedule repeated appointments.
The device connects to the truck’s diagnostic port and communicates through AIRLINK. When the vehicle is ready and testing is required, AIRPASS can complete the test and transmit the result to CARB. Customers can monitor activity and request an on-demand test through the connected platform.
AIRPASS may be a strong fit when:
- The truck is OBD eligible
- The vehicle travels outside Southern California
- Your fleet operates across multiple states
- Repeated testing appointments create downtime
- Trucks are difficult to gather at one yard
- You want app-based visibility into testing activity
- You need to respond to a Notice to Submit or request a retest
AIRPASS is available at $300 per year per truck plus a $99 one-time setup fee, subject to eligibility and vehicle configuration. Review the AIRPASS product page for device and connection details.
How Often Is Testing Required?
Most subject vehicles currently require testing twice per year. Agricultural vehicles and qualifying California-registered recreational motorhomes may follow different schedules.
Beginning October 1, 2027, OBD-equipped vehicles will generally move to quarterly testing, or four tests per year. This change does not apply in the same way to qualifying agricultural vehicles and noncommercial motorhomes that remain on annual schedules.
Passing results may generally be submitted up to 90 days before the compliance deadline. The actual deadline for each vehicle appears in CTC-VIS, so fleet operators should use the account deadline rather than relying on a calendar reminder or memory.
What if the Truck Is Not Ready?
A Not Ready result means one or more OBD monitors have not completed their self-checks. It is not the same as a passing result, and it is not always the same as a failure.
Not Ready commonly occurs after:
- Battery disconnection
- Diagnostic codes being cleared
- Emissions repairs
- Software updates
- Insufficient normal operation
- An active fault that prevents a monitor from completing
The truck may need additional operation under the correct conditions before it can be retested. This is often called completing a drive cycle. Do not repeatedly test a truck immediately after clearing codes unless the vehicle is ready for a valid test.
AIRPASS customers may request unlimited on-demand testing through AIRLINK until the vehicle is ready. Mobile customers can schedule a post-repair retest.
What if I Have a DMV Registration Hold?
A Clean Truck Check-related DMV hold may result when the vehicle is not current on one or more program requirements.
Check whether the vehicle is:
- Reported correctly in CTC-VIS
- Current on the annual fee
- Current on emissions testing
- Clear of open enforcement actions
- Associated with the correct VIN, plate, and registration information
A passing emissions test alone may not remove the hold if another account requirement is incomplete or still processing. Payment and system updates may also take time.
For background on CARB and DMV compliance, see the AIRLIMITS CARB DMV Compliance resource.

What if CARB Issued a Notice to Submit?
A Notice to Submit to Testing (NST) is an enforcement notice requiring the owner to provide a passing Clean Truck Check test.
CARB generally requires the owner to submit a passing test within 30 calendar days of receiving the notice. This requirement is separate from the vehicle’s regular testing schedule.
Act promptly:
- Review the notice and identify the deadline.
- Confirm whether the truck needs OBD, opacity, or visual testing.
- Check whether the vehicle is ready for testing.
- Schedule a credentialed tester or request an AIRPASS test if eligible.
- Confirm that the passing result appears in CTC-VIS.
Do not wait until the final days to discover that the vehicle is Not Ready or that the testing location cannot be accessed.
Common Long Beach Clean Truck Check Scenarios
An out-of-state drayage truck enters California: Out-of-state registration does not automatically create an exemption. An eligible AIRPASS-equipped truck can continue managing testing after leaving Long Beach.
An older construction truck needs testing: A 2012-or-older diesel generally needs opacity and visual testing. Schedule mobile service rather than ordering an OBD-only device.
A truck recently had emissions repairs: The vehicle may need to complete readiness monitors before retesting. Gather repair information and avoid clearing codes again without a plan.
A fleet operates in several states: Eligible OBD trucks may use AIRPASS, while older or non-OBD vehicles can be scheduled for mobile testing based on location and technician availability.
