If you’re running a semi truck with a GVWR over 14,000 pounds and a model year of 2013 or newer, CARB requires you to test. Miss that window and you’re looking at registration holds that pull your truck off the road. Fines start at $1,000 and can climb to $10,000 per vehicle, per day.
You don’t have time to drive across town and wait in line at a testing station. Your truck needs to be on the road, not parked at a facility while someone figures out if your OBD system passes California CARB compliant standards.
We bring the test to you. Our mobile technicians are CARB certified and use approved OBD testing equipment that scans your engine’s emissions data on-site. You get instant reporting through the CTC-VIS system, which updates your vehicle records with CARB and the DMV right away. Your registration stays current, your truck stays compliant, and your operation keeps moving.
We’ve been handling CARB diesel compliance for heavy-duty vehicles in Lake Elsinore, CA since 2005. That’s nearly two decades of keeping trucks legal and operators out of trouble with state regulators.
Lake Elsinore sits right on the I-15 corridor with 592 trucking companies operating in the area. You’re in a transportation hub, which means CARB enforcement isn’t something you can ignore or postpone. The regulations are strict here, and the consequences for non-compliance hit harder when your entire business depends on keeping trucks moving.
Our technicians know the Clean Truck Check requirements inside and out. We’re not learning on your time. We show up with the right equipment, run the test correctly the first time, and make sure your records reflect compliance before we leave.
First, you schedule a time that works for your operation. We come to your location in Lake Elsinore, CA with our mobile testing unit. No need to pull your driver off a route or send your truck to a facility across town.
Our CARB certified technician connects approved OBD testing equipment to your truck’s diagnostic port. We’re scanning your engine’s emissions data to verify it meets California’s heavy-duty vehicle compliance standards. This applies specifically to diesel trucks with a GVWR over 14,000 pounds and a model year of 2013 or newer. If your truck is older or lighter, this isn’t the right test.
The scan takes minutes, not hours. Once complete, we submit your results directly through the CTC-VIS system. That’s the official platform CARB and the DMV use to track compliance. Your vehicle record gets updated immediately, which means your registration renewal goes through without holds or delays.
If your truck passes, you’re done. If there’s an issue flagged by the OBD system, we’ll walk you through what needs attention and what your options are for getting it resolved before your next test window closes.

California’s Clean Truck Check program started in January 2025. If your truck’s registration is due in January or July, your compliance test window is open. You’re required to test semi-annually or quarterly depending on your vehicle’s registration cycle and GVWR classification.
This isn’t optional. CARB truck regulations mandate OBD emissions testing for all diesel vehicles over 14,000 pounds with 2013 or newer engines. The state is tracking this through the CTC-VIS system, and your DMV registration is tied directly to your compliance status.
Lake Elsinore’s location in Riverside County puts you in one of California’s most heavily regulated air quality zones. The South Coast Air Quality Management District covers this area, and enforcement is active. When CARB screeners identify potential high emitters, you have strict deadlines to verify compliance, and missing those deadlines means your truck can’t be registered or legally operated in California.
The regulation is designed to reduce NOx emissions by more than 81 tons per day statewide by 2037. That’s a public health mandate, which means the state isn’t backing off enforcement. You need to stay ahead of your test windows, and you need a provider who understands the technical requirements and the reporting process.
Only heavy-duty diesel trucks with a gross vehicle weight rating over 14,000 pounds and a model year of 2013 or newer are required to undergo CARB emissions testing under the Clean Truck Check program. This applies whether your truck is registered in California or out-of-state but operating here.
The 2013 cutoff is specific because that’s when diesel engines were required to have onboard diagnostics systems that CARB can test. Older trucks fall under different regulations. Lighter vehicles under 14,000 pounds GVWR aren’t subject to this program either.
If you’re not sure whether your truck qualifies, check your registration. If your GVWR is listed above 14,000 pounds and your model year is 2013 or later, you’re required to test. There’s no exemption for low mileage or limited use in California.
Most heavy-duty trucks are required to test semi-annually, which means twice a year. Your specific test schedule depends on when your DMV registration is due. If your registration comes up in January or July, those are your compliance windows.
Some vehicles may be subject to quarterly testing depending on their weight class and emissions profile. CARB determines this based on data collected through the CTC-VIS system and previous test results. If your truck has been flagged as a potential high emitter, you may receive notice that you need to test more frequently.
The key is staying on top of your registration cycle. CARB won’t send you a reminder. It’s your responsibility to know when your window opens and get tested before your registration expires. Missing that window triggers a registration hold, and you can’t renew until you’re compliant.
If your truck fails, the OBD system has flagged an emissions-related issue that needs to be addressed before you can pass. This could be a problem with your diesel particulate filter, your exhaust system, or another component that affects emissions output.
You’ll need to get the issue diagnosed and repaired by a qualified technician. Once the repair is complete, you’ll need to retest to verify compliance. The repair and retest need to happen within your compliance window, or you risk a registration hold.
We can guide you through what the failure code means and what your next steps should be. In some cases, the issue is minor and can be resolved quickly. In others, you may need more extensive work. Either way, you need to address it before your registration comes due, or your truck is off the road until you’re compliant.
Yes. We bring mobile CARB emissions testing directly to your location in Lake Elsinore, CA. That means your truck doesn’t leave your yard, and your driver doesn’t lose time sitting at a testing facility.
Our mobile unit is equipped with the same CARB certified OBD testing devices used at stationary stations. We connect to your truck’s diagnostic port, run the emissions scan, and submit results through the CTC-VIS system on-site. The entire process takes minutes, and your compliance record is updated immediately.
This is especially useful if you’re managing a fleet. We can test multiple trucks in one visit, which keeps your operation running smoothly without pulling vehicles off the road one at a time. Same-day service is available, so you’re not waiting weeks for an appointment.
Testing costs vary depending on your vehicle and whether you need a standard compliance test or additional diagnostics. We price our services fairly with no hidden fees, and you’ll know exactly what you’re paying before any work begins.
What you should really be thinking about is the cost of not testing. CARB fines for non-compliance start at $1,000 per vehicle and can reach $10,000 per vehicle, per day depending on the violation. Registration holds mean your truck can’t legally operate in California, which costs you far more in lost revenue than the price of a compliance test.
If you’re running a fleet in Lake Elsinore, CA, the cost of staying compliant is a known expense you can plan for. The cost of getting caught out of compliance is unpredictable and can shut down your operation. We’re here to make sure that doesn’t happen.
Yes. If your truck operates in California, you’re subject to California CARB compliant regulations regardless of where it’s registered. That includes the Clean Truck Check program for heavy-duty diesel vehicles over 14,000 pounds GVWR with 2013 or newer engines.
CARB enforcement applies to any truck operating on California roads, not just California-registered vehicles. If you’re running interstate routes that pass through the state, or if you’re making deliveries in Lake Elsinore, CA and surrounding areas, you need to comply.
Out-of-state operators sometimes assume they’re exempt, but that’s not how the regulation works. CARB has the authority to enforce compliance on any vehicle operating within state borders. If you’re pulled over or flagged during a roadside inspection and your truck isn’t compliant, you’re facing the same fines and penalties as a California-registered vehicle.
