Frequently Asked Questions
What is included in a Mobile Clean Truck Check?
Our inspections meet CARB requirements and include a visual check of exhaust, filters, and sensors; OBD diagnostic scanning for fault codes (CEL/MIL); DPF and DEF system checks; fault code reporting with repair guidance; and on-site servicing if required. You can also bundle BIT and DOT inspections in one visit.
Who needs a Clean Truck Check?
Any diesel-powered commercial or municipal vehicle with a GVWR of 14,000 pounds or more operating in California—including semi-trucks, buses, RVs, delivery vans, and construction trucks—must comply with Clean Truck Check regulations.
How long does the test take?
Each inspection takes approximately 15–30 minutes per vehicle, depending on make and model. You’ll receive your complete emissions report digitally on the same day.
What happens if my truck fails the inspection?
If your vehicle fails, we’ll provide a detailed fault report and on-site repair options. You’ll need to fix the issue and retest before your registration can be updated. Missed compliance could lead to registration holds or fines.
Can you perform BIT or DOT inspections at the same time?
Yes. We offer bundled inspections, including BIT and DOT, to streamline compliance and reduce downtime by addressing all requirements during a single visit.
