CARB Regulations

California Air Resources Board (C.A.R.B) is responsible for monitoring the regulatory activity of California’s 35 local air districts, helping to maintain healthy air quality. This is to also protect our public from toxic air containments.

CARB is actively enforcing medium & heavy-duty diesel vehicle regulations in support of California’s clean air goals.  Certain vehicles must reduce exhaust emissions by meeting particulate matter(PM) filter requirements, and upgrading to newer engines.

As a commercial dealership, it’s our job to make this transition for our customers as easy and painless as possible.

To determine if a vehicles engine is outdated, it depends on the vehicle size and the year the engine was made, for example:

• Vehicles under 14,000lbs are exempt
• Vehicles between 14,001lbs – 26,000lbs need to replace/repower the engine, if it was made before the year 2009. 2010 and newer engine model years are in compliance.
• Vehicles over 26,001lbs made in 1995 or before need to replace the engine. If the engine model years are between 1996-2009 you would then only need to replace your level 3PM filter. 2010 and newer engine model years are in compliance.

In many cases, buying a new vehicle is the more affordable alternative to replacing the engine in an older vehicle.  Tom’s Truck Center is available to answer any questions you may have, and help you with whatever you decide!
