Your truck stays compliant, your registration stays current, and your business keeps moving. That’s what matters when you’re running a tight operation in Rancho Palos Verdes, CA.
California doesn’t mess around with CARB diesel compliance. If your semi truck is model year 2013 or newer with a GVWR over 14,000 pounds, you’re required to test. Miss it, and you’re looking at fines up to $10,000 per vehicle per day. The DMV can block your registration renewal until you submit a passing test. That’s not a warning—it’s enforcement.
You get a Notice to Submit to Testing, and you’ve got 30 days to complete it. We handle the OBD testing with CARB-certified equipment, generate your compliance certificate, and get you back on the road. No runaround. No delays.
Rancho Palos Verdes has steep grades and winding routes that already make operating heavy-duty vehicles challenging. Adding compliance stress on top of that doesn’t help. You need testing done right the first time so your trucks can handle the terrain and the regulations without breaking stride.
All SMOG Motors focuses exclusively on California CARB compliant testing for trucks that are 2013 or newer. We’re not a general smog shop trying to do everything. We’re certified, we’re trained, and we know the regulations that apply to your fleet.
Rancho Palos Verdes has a tight-knit trucking community—mostly small operators running one to four trucks. You’re dealing with tight margins, unpredictable freight rates, and now stricter emissions rules. We get it because we work with operators like you every day.
Our team holds CARB Authorized Tester Certification, which means we’ve completed the required HD I/M training course and passed the examination. We use California Air Resources Board certified OBD testing devices. When you leave, you have the documentation you need to stay legal and keep your trucks service running smoothly.
You bring your truck in—model year 2013 or newer, GVWR over 14,000 pounds. We connect to your vehicle’s onboard diagnostic system using our CARB-certified testing device. The OBD system reports data on your emissions control equipment, and we verify everything is functioning properly.
If your truck passes, we generate your Clean Truck Check certificate on the spot. You pay the $31.18 annual compliance fee per vehicle, and you’re done. If something flags during the test, we’ll walk you through what needs attention before you can retest.
The whole process is straightforward. No unnecessary steps. No upselling services you don’t need. You’re here for CARB emissions testing, and that’s what we deliver.
Starting in 2025, all applicable heavy-duty vehicles must be tested every six months. Vehicles with 2013 or newer engines will eventually require testing four times per year. That means compliance isn’t a one-time thing—it’s ongoing. Knowing where to go and getting it done efficiently saves you time every cycle.
California uses Remote Emission Monitoring Devices with Automated License Plate Readers to flag potentially high-emitting vehicles. If your truck gets flagged, you’ll receive a Notice to Submit to Testing. That’s your 30-day countdown. We’re here to make sure you meet that deadline without scrambling.

You get OBD testing performed by a CARB credentialed tester using certified equipment. We check your emissions control systems, verify compliance, and issue your certificate if everything checks out. The test applies only to trucks model year 2013 or newer with a GVWR over 14,000 pounds operating on California public roads.
This includes commercial trucks, buses, California-registered motorhomes and RVs, and privately-owned vehicles that meet the weight requirement. If you’re an owner-operator or running a small fleet in Rancho Palos Verdes, CA, this is the testing you need to stay legal.
Rancho Palos Verdes sits in a region with heavy port activity and distribution hubs. Trucks move through here constantly, and enforcement is active. CARB uses roadside monitoring to identify high emitters, and those vehicles get flagged for mandatory testing. You don’t want to be caught off guard.
The freight recession has squeezed margins across California. Rates are stagnant while fuel, insurance, and operational costs keep climbing. Adding a $10,000-per-day fine on top of that can sink a small operation. Compliance isn’t optional—it’s survival.
We’re not here to lecture you about regulations. You already know the stakes. We’re here to get your trucks tested, certified, and back on the road so you can focus on keeping your business moving.
Only trucks that are model year 2013 or newer with a Gross Vehicle Weight Rating over 14,000 pounds. This includes commercial trucks, buses, California-registered motorhomes and RVs, and privately-owned heavy-duty vehicles that operate on California public roads.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this testing requirement doesn’t apply to you. The regulation specifically targets newer heavy-duty vehicles equipped with onboard diagnostic systems.
Starting in 2025, all applicable vehicles must be tested every six months. Vehicles with 2013 or newer engines will eventually require testing four times per year. If you receive a Notice to Submit to Testing, you have 30 days to complete the test and submit a passing result to avoid penalties.
If your truck fails, you’ll need to address whatever issue caused the failure before you can retest. The OBD system will flag specific problems with your emissions control equipment, so you’ll know exactly what needs repair.
Once repairs are completed, you come back for a retest. There’s no limit on how many times you can retest, but you need to get a passing result within the 30-day window if you’ve received a Notice to Submit to Testing.
Failing the test doesn’t automatically trigger fines, but failing to submit a passing test within the required timeframe does. That’s when you’re looking at penalties up to $10,000 per vehicle per day, plus DMV registration holds that prevent you from renewing your vehicle registration. Getting the repairs done quickly and retesting keeps you out of that situation.
The state-mandated compliance fee is $31.18 per vehicle annually. That fee goes directly to California as part of the Heavy-Duty Vehicle Inspection and Maintenance program. It’s not optional, and it’s the same across the state.
Testing fees vary by provider, so it’s worth asking upfront what you’ll pay for the actual OBD test and certificate generation. Some shops charge separately for the test and the state fee, while others bundle it.
If your truck fails and needs repairs, those costs are separate and depend entirely on what’s wrong with your emissions control system. Repairs aren’t part of the testing service—they’re done by a qualified mechanic before you return for a retest. Staying on top of maintenance and addressing issues early can help you avoid expensive repairs when it’s time to test.
If you haven’t received a Notice to Submit to Testing, you’re not required to test immediately. However, California uses Remote Emission Monitoring Devices with Automated License Plate Readers at various locations to screen for high emitters. If your truck gets flagged, you’ll receive a notice in the mail.
Starting in 2025, the testing schedule changes. All applicable heavy-duty vehicles must be tested every six months, and vehicles with 2013 or newer engines will eventually require testing four times per year. At that point, testing becomes a regular part of your compliance routine whether or not you receive a specific notice.
Getting ahead of the requirement makes sense if you want to avoid the last-minute rush. Testing proactively also gives you time to address any issues before they become urgent. If your truck is operating in California and meets the criteria—2013 or newer, GVWR over 14,000 pounds—you’ll be testing regularly soon enough.
Testing must be performed by a CARB credentialed tester who has completed the HD I/M training course, passed the examination, and received CARB Authorized Tester Certification. Not every smog shop is certified to perform heavy-duty vehicle compliance testing.
You need to find a location that specifically handles Clean Truck Check testing for trucks model year 2013 or newer. General smog check stations that only test passenger vehicles won’t have the equipment or certification to test your heavy-duty truck.
In Rancho Palos Verdes, CA, and the surrounding South Bay area, certified testing locations are available, but they’re not as common as standard smog shops. Calling ahead to confirm the shop is certified for heavy-duty CARB emissions testing saves you a wasted trip. Make sure they have the CARB-certified OBD testing device and can issue the compliance certificate you need.
You receive a Clean Truck Check certificate that confirms your vehicle passed the OBD emissions test. This certificate is your proof of compliance and gets submitted to CARB and the DMV to clear any testing requirements or registration holds.
The certificate includes your vehicle identification number, test date, and confirmation that your emissions control equipment is functioning properly. Keep a copy for your records, especially if you’re managing multiple trucks or need to provide compliance documentation to clients or regulatory agencies.
If you received a Notice to Submit to Testing, submitting your passing certificate within the 30-day window clears the requirement and prevents penalties. If your registration was on hold due to non-compliance, the passing test removes the block so you can renew. The certificate is the key document that keeps your truck legal and operational on California roads.
