If you’re running trucks in California, you already know the state doesn’t mess around with emissions. CARB’s Heavy-Duty Vehicle Inspection and Maintenance program requires semi-annual testing for diesel and alternative fuel trucks model year 2013 or newer with a GVWR over 14,000 pounds. Miss your deadline and the DMV blocks your registration. Keep missing it and you’re looking at fines that can hit $10,000 per vehicle per day.
You need a passing emissions test submitted before your compliance deadline, or your trucks sit. That’s not a scare tactic, that’s the regulation. CARB collected over $21 million in penalties in 2022 alone, and they’re actively monitoring compliance with roadside devices and enforcement teams across California highways.
We handle CARB emissions testing for heavy-duty trucks at our Hemet location. You get tested by a CARB-credentialed tester, results submitted directly into the CTC-VIS system, and documentation you can show freight brokers, ports, or anyone else asking for proof. You can submit a passing test up to 90 days before your deadline, which gives you time to handle repairs if something comes back flagged.
We operate in Hemet with CARB-credentialed testers who’ve completed the required training and maintain their certification through CARB’s renewal process. We’re not a mobile service bouncing around the Inland Empire. We’re a fixed location you can count on when your compliance deadline is coming up.
Hemet sits right in the middle of major transportation corridors serving the I-15 and CA-91 routes. With over 500 active carriers operating in this area, you’re not the only one dealing with CARB compliance. But you are dealing with a regulation that started enforcement in October 2024, and every compliance deadline on or after January 1, 2025 requires a passing emissions test.
We focus exclusively on model year 2013 and newer trucks over 14,000 pounds GVWR because that’s what the regulation covers. If your truck doesn’t meet those specs, this isn’t the service you need. If it does, we’re set up to get you tested and compliant.
First, your truck needs to be registered in CARB’s CTC-VIS system and your annual compliance fee needs to be paid. If that’s not done, we can help you get that squared away. Once you’re in the system, you’ll have a compliance deadline that requires a passing emissions test twice a year. Starting in October 2027, trucks with OBD systems will move to quarterly testing, so plan for that shift.
You bring your truck to our Hemet location. We run the emissions test using CARB-approved equipment and procedures. The test checks your truck’s onboard diagnostics and emissions output to verify it meets California’s standards. If you pass, we submit the results directly into CTC-VIS, and you’re compliant. If something flags, you’ll know what needs repair, and you have up to 90 days before your deadline to get it fixed and retested.
You can submit a passing test up to 90 days early, which is smart if you’re managing a fleet with multiple deadlines. If CARB sends you a Notice to Submit to Testing, you have 30 days to get a passing test submitted. Don’t wait until the last minute. Registration blocks happen fast, and once your truck is flagged, it can’t legally operate on California roads until you’re compliant.

You get a full emissions test performed by a CARB-credentialed tester who’s trained on the Heavy-Duty I/M regulation. We test trucks with diesel engines, alternative fuels, and hybrid systems, as long as they’re model year 2013 or newer and have a GVWR over 14,000 pounds. The test covers OBD diagnostics and emissions output, and results are submitted directly into CARB’s CTC-VIS database.
You’ll receive documentation showing your compliance status, which you can provide to freight brokers, port authorities, rail yards, or any entity requiring proof of CARB compliance. This matters more than you might think. Ports and major logistics hubs in California are increasingly requiring compliance verification before they’ll accept loads, and out-of-state carriers operating in California are subject to the same rules as California-registered trucks.
Hemet’s location in the Inland Empire puts you close to major freight routes without the hassle of navigating into LA or Orange County for testing. With the regulation now in full enforcement and penalties actively being issued, getting tested on time isn’t optional. CARB’s roadside monitoring devices are scanning trucks on highways, and if your truck is flagged as non-compliant, you’re getting pulled over. We help you stay ahead of that.
Yes. If your truck operates on California public roads or highways, it needs CARB compliance testing regardless of where it’s registered. The Heavy-Duty Vehicle Inspection and Maintenance regulation applies to all trucks model year 2013 or newer with a GVWR over 14,000 pounds that operate in California, even if they’re only passing through.
Out-of-state carriers are required to register in the CTC-VIS system, pay the annual compliance fee, and submit passing emissions tests on the same schedule as California-registered trucks. CARB doesn’t care what state your plates are from. If you’re on California roads, you’re subject to California emissions regulations.
If you get flagged by CARB’s roadside monitoring or pulled over during an enforcement check and you’re not compliant, your truck can be sidelined until you get a passing test submitted. That’s downtime you can’t afford, especially if you’re running loads on a tight schedule.
Right now, you need a passing emissions test twice a year. That’s semi-annual testing, meaning every six months you need to submit a passing test before your compliance deadline. Your specific deadline is assigned when you register in the CTC-VIS system, and it’s based on your truck’s VIN and registration details.
Starting in October 2027, trucks equipped with OBD systems will move to quarterly testing. That means four times a year instead of two. CARB is tightening the schedule to increase monitoring frequency, so if you’re managing a fleet, you need to plan for that shift now.
You can submit a passing test up to 90 days before your deadline, which gives you a buffer if repairs are needed. If CARB sends you a Notice to Submit to Testing, you only have 30 days to get a passing test in, so don’t ignore those notices. Missing a deadline triggers a DMV registration block, and you can’t renew your registration until you’re compliant.
If your truck fails, you’ll get a detailed report showing what flagged during the test. Most failures are related to OBD system issues, emissions output exceeding limits, or malfunctioning emissions control equipment. You’ll need to get the issue repaired and then come back for a retest.
The good news is you can test up to 90 days before your compliance deadline, so if you fail, you have time to get repairs done and retest before the deadline hits. If you wait until the last minute and fail, you’re in a tougher spot because repairs take time and you’re racing the clock.
Once repairs are done and you pass the retest, we submit the passing results into CTC-VIS and you’re compliant. If you miss your deadline entirely, the DMV blocks your registration and CARB can issue penalties. Fines start adding up fast, and they can reach $10,000 per vehicle per day for continued non-compliance. Get ahead of it. Test early, and if something fails, you have time to fix it.
No. The Heavy-Duty Vehicle Inspection and Maintenance regulation only applies to trucks that are model year 2013 or newer and have a GVWR over 14,000 pounds. If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this regulation doesn’t apply to you.
CARB set the 2013 cutoff because that’s when OBD systems became standard on heavy-duty trucks, making emissions monitoring more feasible. Lighter trucks and older trucks may still need standard smog checks depending on their classification, but they’re not subject to the Heavy-Duty I/M program.
If you’re not sure whether your truck qualifies, check your registration and GVWR. If it’s 2013 or newer and over 14,000 pounds, you need CARB compliance testing. If it doesn’t meet both of those criteria, you’re not required to participate in this program.
Testing typically takes 30 to 60 minutes depending on your truck’s configuration and whether any issues come up during the diagnostic check. We run the OBD diagnostics, check emissions output, and verify that your truck’s emissions control systems are functioning properly. If everything checks out, you’re done and we submit the results.
Cost varies depending on the type of truck and the complexity of the test, but you’re looking at a straightforward service fee for the test itself. That’s separate from CARB’s annual compliance fee, which you pay directly to CARB when you register in the CTC-VIS system. The compliance fee is around $300 per year per truck, but check CARB’s current fee schedule because it can change.
Compare that to the cost of non-compliance. A single day of penalties can hit $10,000 per vehicle. A registration block means your truck sits until you’re compliant, and that’s lost revenue every day it’s not rolling. Testing twice a year is a small investment compared to the financial hit you’ll take if you ignore it.
CARB compliance testing has to be performed by a CARB-credentialed tester at an authorized location. Not every smog shop can do this. The tester has to complete CARB’s training program, pass an exam with at least an 80% score, and maintain their credential through renewal every two years.
We’re a CARB-credentialed testing location in Hemet, which means we’re authorized to perform Heavy-Duty I/M testing and submit results directly into the CTC-VIS system. You can’t just go to any smog shop and expect them to handle CARB compliance for heavy-duty trucks. The equipment, training, and certification requirements are different.
Some mobile testing services operate in the area, but if you’re managing a fleet or need consistent access to testing, a fixed location gives you more reliability. We’re here when you need us, and we’re set up specifically to handle model year 2013 and newer trucks over 14,000 pounds GVWR. That’s our focus, and that’s what we’re credentialed to do.
