If you own or operate a diesel truck in California or have used it for a while, you may have received a Clean Truck Check notice from the DMV or CARB. Many truck owners are unaware of the regulations, deadlines and clean truck check notices.

That is where High Tech Auto in San Marcos comes in to help. We can explain Clean Truck Check requirements and help you understand the Clean Truck Check process to ensure your vehicle never causes compliance issues, prevent penalties and registration matters by performing inspections and working on any necessary repair. 

What Is the Clean Truck Check Program?

The Clean Truck Check process is a process that helps manufacturers and builders to verify and confirm a vehicle has passed vehicle cleanliness and is in compliance with regulations. Clean Truck Check is a California program that requires most diesel trucks and buses to comply with regular emissions inspections. The idea is to make air cleaner and the vehicles on the road operate in a clean and efficient manner. If your truck has to take part and you don’t pass the test, you run the risk of: 

  • Registration holds. 
  • Fines or penalties. 
  • Trouble renewing your vehicle. 
  • Being taken out of service. 

You may require Clean Truck Check if: 

  • You own a diesel truck or bus that is registered in California. 
  • You were notified by the DMV or CARB of your filing. 
  • Your registration renewal is being put on hold. 
  • You drive your truck for work, delivery or business. 
  • You don’t know whether your vehicle is legal.

What Happens During a Clean Truck Check Visit?

During the inspection, technicians verify that your truck’s emissions systems are working correctly.

This may include:

  • Checking the engine control system
  • Inspecting emissions control components
  • Reviewing onboard diagnostic systems
  • Performing emissions or smoke opacity testing when required

These tests confirm the truck is operating within California emissions limits.
