If your truck isn’t CARB compliant, you’re looking at fines up to $10,000 per vehicle, per day. Those penalties compound daily. The DMV can place a registration hold on non-compliant trucks, which means your vehicle can’t legally operate on California roads until you submit a passing test.
Starting January 1, 2025, all heavy-duty trucks over 14,000 pounds GVWR need semi-annual Clean Truck Check testing. That’s twice a year, every year. Miss a deadline and you’ve got 30 days to submit a passing test or face enforcement action.
We handle the testing at your yard, job site, or wherever your trucks are parked. You don’t lose a day driving to a station. Our CARB credentialed testers run the inspection, upload results instantly, and clear any DMV holds on the spot. Your trucks stay compliant, your business keeps moving, and you avoid the financial nightmare of non-compliance.
We serve trucking companies, owner-operators, and fleet managers throughout La Puente and the surrounding San Gabriel Valley. This area sits right off the I-60 corridor with direct access to the Ports of Los Angeles and Long Beach—which means heavy-duty diesel traffic is constant here.
We’re not a general smog shop trying to figure out heavy-duty compliance. Our testers are CARB credentialed, which means they’ve completed the state’s official training and passed the required exams. We carry the proper licensing and $2 million in liability insurance with mobile service coverage.
La Puente has nearly 1,800 truck drivers and freight workers in the local economy. We understand the pressure you’re under to keep trucks moving and compliant without losing billable hours sitting at a testing facility.
You schedule an appointment—same-day availability in most cases. We bring the testing equipment to your location. No need to pull trucks out of service or drive across town.
Our tester performs the Clean Truck Check using CARB-approved equipment that meets SAE J1667 specifications. For 2013 and newer trucks with OBD systems, we’re running diagnostics on emissions controls and checking for fault codes. The test takes about 15-20 minutes per vehicle.
Once the test is complete, results are uploaded directly to CARB’s system. If there’s a DMV registration hold, it gets cleared immediately. You receive documentation showing compliance, and your trucks are good to go for the next six months.
If a vehicle doesn’t pass, we’ll tell you exactly what’s flagged and what needs attention. You’ll still have time within your 30-day window to address the issue and retest before facing penalties.

California’s Clean Truck Check program applies to diesel and alternative-fueled heavy-duty vehicles with a GVWR over 14,000 pounds. If your truck is model year 2013 or newer with an OBD system, you’re required to test twice per year starting in 2025.
You’ll also need to pay an annual compliance fee of $31.18 per vehicle. That fee goes to CARB, not the testing facility. Testing costs are separate—typically between $129 and $199 depending on fleet size.
La Puente’s location near major freight corridors means CARB enforcement is active here. They conduct random roadside inspections at weigh stations, border crossings, and fleet facilities. If your truck gets pulled and you’re not compliant, the citation is immediate.
Heavy-duty vehicles make up only 3% of California’s vehicle population but generate over 50% of nitrogen oxide and diesel particulate pollution. That’s why the state is aggressive about enforcement. The program is projected to prevent 7,500 air-quality related deaths and deliver $75 billion in health benefits—so this isn’t going away.
If your truck has a GVWR over 14,000 pounds and is model year 2013 or newer, yes. California’s Clean Truck Check program requires semi-annual emissions testing for these vehicles starting January 1, 2025.
This applies to most diesel and alternative-fueled heavy-duty trucks operating in California, regardless of where they’re registered. If you’re driving through or based in the state, compliance is mandatory.
Older trucks or vehicles under 14,000 pounds GVWR are not part of this program. The requirement is specifically for newer heavy-duty trucks with OBD emissions systems.
CARB will send you a Notice to Submit to Testing. You have 30 calendar days from that notice to complete and submit a passing test. If you miss that deadline, the DMV places a registration hold on your vehicle.
A registration hold means your truck cannot be legally registered or operated on California roads. You’ll also face fines up to $10,000 per vehicle, per day. Those penalties compound daily until you come into compliance.
CARB collected $21.5 million in penalties in 2022 alone, and enforcement is increasing. The financial and operational risk of non-compliance is significant—especially if you’re running multiple trucks.
Yes. We bring the testing equipment directly to your location—whether that’s your yard, a job site, or wherever your trucks are parked. You don’t need to take vehicles out of service or drive to a facility.
Mobile testing minimizes downtime and makes it easier to stay compliant, especially if you’re managing a fleet. We offer same-day appointments in most cases and can test multiple vehicles in one visit.
Once testing is complete, results are uploaded instantly to CARB. If there’s a DMV hold, it’s cleared on the spot. You get documentation proving compliance, and your trucks are legal to operate for the next six months.
Pricing typically starts around $199 per vehicle for individual trucks. If you’re testing 2-5 vehicles, the rate drops to about $149 per truck. For fleets of six or more, pricing is usually around $129 per vehicle.
These are testing fees. You’ll also need to pay CARB’s annual compliance fee of $31.18 per vehicle separately. That fee goes directly to the state, not the testing provider.
Fleet pricing makes compliance more affordable if you’re running multiple trucks. Most mobile testing services offer discounts for multi-vehicle accounts, and scheduling everything in one visit saves time and coordination hassle.
If your truck doesn’t pass, we’ll tell you exactly what triggered the failure—usually a fault code or emissions system issue. You’ll have documentation showing what needs to be repaired.
You’re still within your 30-day compliance window, so you have time to address the problem and retest before facing penalties. Most failures are related to malfunctioning sensors, DPF issues, or EGR system faults.
Once repairs are made, you can schedule a retest. If the truck passes, results get uploaded to CARB and any registration hold is cleared. The key is acting quickly so you don’t run out of time and trigger fines or operational restrictions.
The testing requirements are the same whether you own one truck or fifty. If your vehicle is 2013 or newer with a GVWR over 14,000 pounds, you need semi-annual Clean Truck Check testing starting in 2025.
Owner-operators face the same penalties for non-compliance—up to $10,000 per vehicle, per day, plus DMV registration holds. The financial impact can be devastating if you’re running a single truck and it gets sidelined.
The main difference is that fleets often get volume pricing on testing and can coordinate inspections more efficiently. But the regulatory burden and enforcement risk are identical regardless of fleet size.
