You’re running a business, not chasing paperwork. When your truck needs Clean Truck Check testing, you need it done correctly the first time—by someone who actually knows CARB regulations and won’t waste your day.
That’s what you get here. We test 2013 and newer diesel trucks over 14,000 pounds using CARB certified equipment and submit results directly to the state database. You get documentation proving compliance, and the DMV gets confirmation that keeps your registration clear.
Testing happens every six months right now, but that’s doubling to four times a year starting October 2027. The window to test opens 90 days before your deadline, which gives you time to address issues if something comes up. Miss your deadline and you’re looking at registration blocks, citations, and potential fines up to $10,000 per year. We help you stay ahead of that.
We serve the Rancho Mirage trucking community with CARB credentialed testers who completed official state training and certification. We’re not guessing at regulations—we’re trained on them.
Rancho Mirage has around 30 active trucking companies, from single-truck owner-operators to small fleets. Most of you are dealing with the same compliance headaches: confusing rules, tight deadlines, and the constant worry about getting blocked at registration. We’ve built our service around making that process straightforward.
You’re not getting a generic smog shop trying to figure out heavy-duty diesel compliance. You’re getting testers who handle OBD scans on 2013+ trucks daily and know exactly what CARB requires for Clean Truck Check submissions.
You bring your 2013 or newer truck (over 14,000 pounds GVWR) to our Rancho Mirage location. We plug into your OBD system using CARB certified testing equipment and run the required engine diagnostics. The scan checks emissions data, monitors, and readiness status to confirm your truck meets California’s diesel compliance standards.
If everything passes, we submit results directly to the Clean Truck Check Vehicle Inspection System (CTC-VIS). You get documentation immediately, and the state database updates to show you’re compliant. That keeps the DMV from flagging your registration.
If something doesn’t pass, you’ll know exactly what the issue is. You have up to 90 days before your deadline to get repairs done and retest. That buffer exists specifically so you’re not scrambling at the last minute or facing enforcement action because of a fixable problem.
The whole process typically takes under an hour if your truck passes. You’re not sitting around all day—you’re getting tested, getting proof, and getting back to work.

California’s Clean Truck Check program requires testing every six months for diesel trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. You also pay an annual compliance fee—$31.18 for 2025—and your truck must be registered in the state database.
Testing uses OBD data scans, not tailpipe tests. We’re checking what your engine computer reports about emissions performance, monitor status, and fault codes. CARB sets the pass/fail criteria, and results get submitted electronically to CTC-VIS.
Here’s what matters for Rancho Mirage operators: you can test up to 90 days early, which is critical during busy seasons when you can’t afford downtime. Testing frequency doubles in October 2027 to four times per year, so planning ahead becomes even more important.
Non-compliance isn’t just a ticket. It’s DMV registration blocks that sideline your truck, plus fines that can hit $10,000 annually. If you’re an owner-operator or running a small fleet, that’s devastating. Shippers who hire non-compliant carriers also face penalties, which means your compliance status affects your ability to get loads.
Yes, if your truck operates in California. The Clean Truck Check program applies to nearly all diesel trucks over 14,000 pounds GVWR that drive on California roads, regardless of where they’re registered.
Out-of-state trucks need to register in the CARB database and complete testing on the same schedule as California-registered vehicles. That means testing every six months (increasing to four times yearly in October 2027) and paying the annual compliance fee.
If you’re running interstate routes that bring you through California regularly, you’re subject to these rules. Enforcement happens at weigh stations, during roadside inspections, and through database checks. Non-compliance can result in citations and being pulled off the road until you’re legal.
You get a detailed report showing exactly what failed—usually related to monitor readiness, fault codes, or emissions system performance. That gives you and your mechanic clear direction on what needs repair.
You’re allowed to retest once repairs are complete, and you have up to 90 days before your compliance deadline to get everything sorted. That window exists specifically so a failed test doesn’t immediately shut down your operation.
If you’re close to your deadline and fail, you need to move fast. Operating a non-compliant truck after your deadline triggers registration blocks and potential fines. Most failures are fixable—sensor issues, incomplete drive cycles, or minor emissions component problems—but they need attention before you can pass and submit clean results to the state.
Right now, testing is required every six months for diesel trucks that are 2013 or newer with a GVWR over 14,000 pounds. You’ll receive deadline notifications from CARB, and you can test up to 90 days before that deadline.
Starting October 2027, the frequency doubles to four times per year. That’s a significant change that will require tighter scheduling, especially if you’re managing multiple trucks or running high-mileage operations.
The testing schedule is tied to your truck’s VIN and registration in the CARB database. Missing a deadline isn’t something you can ignore—it triggers automatic DMV registration blocks and opens you up to enforcement action. Setting reminders well before your deadline and using that 90-day early testing window helps you avoid last-minute problems.
No. Our CARB compliant testing service is specifically for trucks that are model year 2013 or newer AND have a GVWR over 14,000 pounds. This is the equipment class that requires OBD-based Clean Truck Check testing under California regulations.
Older trucks (pre-2013 models) and lighter vehicles fall under different testing requirements or may be exempt entirely depending on their weight class and use. The 2013 cutoff exists because that’s when OBD systems became standard on heavy-duty diesel engines, making electronic testing possible.
If you’re unsure whether your truck qualifies, check your registration for the model year and GVWR. Both criteria must be met. Trucks under 14,000 pounds or older than 2013 need different services that we don’t provide at this location.
You get immediate proof of compliance that shows your truck passed and results were submitted to the Clean Truck Check Vehicle Inspection System. This documentation includes your VIN, test date, results, and confirmation that the state database was updated.
Keep this paperwork in your truck. If you’re stopped at a weigh station or during a roadside inspection, it proves you’re current on compliance requirements. The DMV also uses database records to clear registration holds, but having physical proof prevents delays if there’s any lag in system updates.
Your compliance status is also visible in the CARB database, which shippers and brokers can check. Some companies won’t contract with carriers who aren’t current on Clean Truck Check testing, so staying compliant protects your ability to get loads. The documentation we provide covers all those bases.
You can test up to 90 days before your compliance deadline, and you should use that window. Testing early gives you time to handle repairs if something fails, and it keeps you from scrambling during your busiest seasons.
Most operators in Rancho Mirage schedule testing 30-60 days out from their deadline. That’s early enough to avoid the rush but not so early that you forget about it. If you’re managing multiple trucks, stagger your testing dates so you’re not bringing everything in at once.
The worst approach is waiting until the last week. If you fail, you won’t have time to repair and retest before your deadline hits. That means registration blocks, potential fines, and trucks sitting idle when they should be earning. Plan ahead, test early, and you’ll never deal with compliance emergencies.
