New round of engines targeted by CARB

As of January 1, 2013, California’s Truck and Bus regulation is now targeting 2000-2004 engine model year trucks.
If you are operating a 2000-2004 engine model year truck in California (including out-of-state vehicles) with a gross vehicle weight of 14,000 lbs or greater, your truck must be equipped with an approved particulate matter filter. Installing the filter on these trucks will satisfy state law through the year 2023 at which time you will be required to replace the engine with an engine model year 2010 or better.
The California Air Resources Board is warning truckers that
inspectors will be checking for compliance at random roadside locations, truck stops, weigh stations, distribution centers, fleet facilities and various other locations.
A non-compliant vehicle (including out-of-state vehicles) may not be legally operated in California. Penalties start at a minimum of $1,000 per violation
per month and increase over time.
