  • HDVIP testing
  • Processing of certifications
  • Keeping records of tests, cleanings, and emissions

CARB Compliant Strategies

We can maintain your trucks health and overall emissions system so you’re compliant with CARB’s increasing requirements. The National Clean Diesel Campaign enforced by the EPA has made it difficult for fleets of trucks or businesses.

Certificate of Conformity

Clean Air Act is requiring more information about diesel vehicles, their engines, and how they interact with their emissions system. Each diesel engine powered vehicles is required to have a ‘Certificate of Conformity’. This certificate is part of the compliance programs by ensuring that your engine meets emissions standards. Under the CAA the EPA has also created the ‘verified’ system. The EPA is making sure that you comply with what they want to make sure your vehicle is through verification.

Verified System

  • Creating an online account
  • Registration
  • Verification of your engine and your vehicle emissions requirements
  • If you meet certain criteria (as a Heavy-Duty Diesel Driver or Fleet Owner) you must keep your records of this for at least two of the previous years

CARB Regulations for Heavy Duty Diesel Trucks and Buses

The Truck and Bus regulations CARB has been working on with the EPA is a phase in program to reduce PM and other emissions found to be coming diesel engine vehicles. Did you know that there is a program that is strictly for monitoring and handling air pollution complaints, specifically in regards to diesel emissions?   Emissions standards for California by CARB are becoming increasingly strict, while ARB enforces Air Pollution programs throughout the U.S. The Clean Diesel Regulations apply to nearly all diesel fueled trucks and buses with a gross vehicle weight rating (GVWR) greater than 14,000 pounds that are privately or federally owned and for privately and publicly owned school buses.

  • By January 1, 2023, almost all trucks and buses will have to be equipped with 2010 model year engines or equivalent.
  • Since January 1, 2012, heavier trucks have to be retrofitted with PM filters (DPFs), and
  • Starting January 1, 2015, lighter and older trucks have to be replaced.

  • Vehicles that have to be retrofitted.
  • The rule applies to diesel fueled trucks and buses, privately and federally owned and school buses privately and publicly owned, vehicles with a GVWR greater than 14,000 pounds.<
  • As of January 2015, the penalty for non-compliant trucks can be a fine of up to $1,000 violation per day, though CARB usually only enforces the fine once per month.
  • If you go to the ARB official website they have posted all settlements in regards to the diesel emissions program, which can be viewed at

  • Idling Limits:There is also a limit on how long you can idle in one place, which is restricted to 5 minutes, while for buses idle time is much less.
  • Emission Control Labels:Must be clear and in all commercial heavy-duty diesel vehicles to prove that at least their engine meets U.S. federal engine emissions standards for the engine model year.
