Clean Truck Check for Out-of-State Vehicles Entering California

Title: Clean Truck Check for Out-of-State Trucks in California Meta Description: Out-of-state truckers must still comply with California’s Clean Truck Check. APDCarb makes it easy with mobile testing.

What Out-of-State Truckers Must Know

Even if your truck isn’t registered in California, you must comply with the Clean Truck Check if you operate in the state. This requirement applies to any vehicle over 14,000 lbs GVWR, regardless of registration location.

If you’re a long-haul driver, regional operator, or cross-country logistics provider passing through California, you are not exempt.

What’s Required?

You’ll need:

  • A Clean Truck Check emissions test
  • Verified reporting to CARB
  • Proof of compliance for future enforcement sweeps

Failure to comply can result in:

  • Fines up to $1,000 per vehicle
  • Entry denial at California borders
  • DMV registration blocks
