You’re running a business, not playing games with CARB regulations. Every hour your truck sits at a testing facility is money you’re not making. Every missed compliance deadline is a potential $10,000 fine waiting to happen.
Here’s what actually matters: your truck passes inspection, the results upload to CARB’s database immediately, and you keep rolling. That’s it. No runaround, no wasted trips, no wondering if you’re legal to operate in California.
We bring CARB certified smog check testing directly to your location in East Los Angeles. Your 2013 or newer heavy-duty diesel truck gets tested where it sits. You get digital proof of compliance the same day. CARB gets their data. You get back to work.
This only applies to trucks with a model year of 2013 or newer and a gross vehicle weight rating over 14,000 pounds. If your rig doesn’t fit that description, this service won’t work for you. But if it does, you’re looking at the fastest way to stay compliant without losing a day’s pay.
We operate in one of the most heavily enforced trucking corridors in California. Between January 2018 and May 2019, CARB audited 179 fleets right here in East Los Angeles, Boyle Heights, and West Commerce. They placed DMV registration holds on 240 vehicles. That’s not a scare tactic—that’s public record.
We’ve built our service around what truckers in this area actually need: fast mobile testing, same-day results, and someone who understands that compliance isn’t optional when you’re operating near the ports and major freight routes. You’re not our first rodeo, and you won’t be treated like one.
We’re CARB-credentialed, licensed, insured, and equipped with the OBD testing devices required for Clean Truck Check inspections. Our results go straight into the state database. No delays, no paperwork nightmares, no second-guessing whether it actually counted.
You schedule a time that works for your operation. We show up at your yard, job site, or wherever your truck is parked in East Los Angeles. No need to drive anywhere or wait in line.
Our technician connects CARB-approved diagnostic equipment to your truck’s onboard diagnostics port. For 2013 and newer heavy-duty vehicles, this is a Clean Truck Check OBD inspection. We’re checking that your emissions control systems are functioning properly and that your truck meets California’s heavy-duty vehicle compliance standards.
The test takes about 20 to 30 minutes depending on your truck’s system. Once complete, we upload the results directly to CARB’s database. You get a digital record immediately. If your truck passes, you’re done—fully compliant and cleared to operate.
If there’s an issue, we’ll tell you exactly what failed and what needs attention. No guessing, no vague explanations. You’ll know what the problem is and what it takes to fix it so you can get back on the road legally.
This is required testing. Most heavy-duty diesel trucks need it twice a year, and CARB is moving toward four times annually for certain vehicles. Missing it means registration holds, fines, and your truck sitting idle while you scramble to catch up.

California’s Clean Truck Check program applies to nearly all diesel and alternative-fuel trucks over 14,000 pounds GVWR operating on public roads. If your truck is model year 2013 or newer, it falls under the OBD-based testing requirement. That’s what we handle.
You’re required to report your vehicle, pay annual compliance fees to CARB, and complete emissions testing on their schedule. For most trucks, that’s twice a year right now. Skip it, and the DMV won’t renew your registration. Operate without compliance, and you’re looking at fines that start at $10,000 per vehicle, per day.
East Los Angeles sees aggressive enforcement because of proximity to the ports and high freight traffic. CARB isn’t issuing warnings here—they’re issuing holds and penalties. You need to stay ahead of it, not react after you’ve already been flagged.
Our service covers the emissions compliance testing portion. We test your truck’s OBD system, verify that emissions controls are working, and submit results to CARB the same day. You handle registration and fees separately, but the testing itself—we’ve got that covered, and we come to you.
If your semi truck has a gross vehicle weight rating over 14,000 pounds and a model year of 2013 or newer, yes—you need CARB compliant emissions testing under the Clean Truck Check program. This applies to diesel and alternative-fuel trucks operating on California roads, including personal and commercial vehicles.
Older trucks and lighter vehicles fall under different rules or may be exempt, but anything 2013 or newer in the heavy-duty category is required to test. Most trucks in this range need testing twice a year, with some moving to four times annually depending on CARB’s schedule.
If you’re running freight in or through East Los Angeles, this isn’t optional. CARB enforcement is active in this area, and operating without current compliance can result in registration holds and fines starting at $10,000 per vehicle.
The actual Clean Truck Check OBD inspection takes about 20 to 30 minutes once our technician connects the diagnostic equipment to your truck. The process is straightforward: we plug into your onboard diagnostics port, run the emissions system check, and record the results.
If everything passes, we upload the data to CARB’s database immediately and you get digital confirmation the same day. Total time from start to finish is usually under an hour, including setup and paperwork.
The advantage of mobile testing is that you’re not losing drive time or sitting in a queue at a fixed facility. We come to your location in East Los Angeles, test your truck where it’s parked, and you’re back to work without the hassle of taking it somewhere and waiting around.
If your truck fails, we’ll tell you exactly what triggered the failure—whether it’s a sensor issue, a malfunctioning emissions control component, or something else flagged by the OBD system. You’ll get a clear explanation, not vague technician-speak.
From there, you’ll need to get the issue repaired before you can retest and achieve compliance. We can point you toward what needs fixing, but the actual repair work has to be done by a qualified mechanic. Once repairs are complete, we can come back and retest your truck.
Operating a truck that’s failed emissions testing puts you at risk for penalties if you’re stopped or audited by CARB. It’s not worth the gamble. Get it fixed, get it retested, and get back to legal operation. The cost of repairs is almost always less than the cost of fines and downtime from a registration hold.
Yes, we offer same-day mobile CARB emissions testing in East Los Angeles depending on availability. If you’re facing a deadline or need emergency testing to avoid a compliance lapse, contact us as early in the day as possible and we’ll do our best to fit you in.
Same-day service is especially useful if you’ve just realized your testing is overdue or if you’re dealing with an urgent situation like a CARB audit or registration issue. We understand that trucking doesn’t run on a 9-to-5 schedule, and neither do compliance problems.
Keep in mind that same-day availability isn’t guaranteed during peak periods, so it’s always better to schedule ahead when you can. But if you’re in a bind, we’ll work with you to get your truck tested and compliant as quickly as possible.
Pricing depends on your specific situation—whether you’re testing a single truck or managing a fleet, and whether you need standard or same-day service. We keep our rates competitive and transparent, and we offer fleet discounts if you’re testing multiple vehicles.
Mobile service costs more than dragging your truck to a fixed facility, but you’re paying for convenience and time savings. Every hour your truck isn’t driving is lost revenue. We bring the test to you, complete it fast, and get you back to work without the downtime of traditional testing.

A regular smog test is what passenger cars and light-duty vehicles go through at your typical smog check station. CARB Clean Truck Check is specifically for heavy-duty vehicles over 14,000 pounds GVWR with 2013 or newer engines. It’s a different program with different equipment and different reporting requirements.
Clean Truck Check uses OBD-based diagnostics to verify that your truck’s emissions control systems are functioning properly. The results get uploaded directly to CARB’s database, and compliance is tracked at the state level. You can’t just go to any smog shop—this requires CARB-credentialed providers with the right equipment.
If you’re driving a semi truck, box truck, or other heavy-duty diesel vehicle in California, you’re in the Clean Truck Check program, not the standard smog check system. The rules are stricter, the testing is more frequent, and the penalties for non-compliance are significantly higher.
