California Standards for Diesel Truck Owners

June 24th, 2019 by

With the 2020 deadlines approaching, The California Environmental Protection Agency has new requirements for diesel truck owners. If you own a diesel truck, bus, trailer, or transport refrigeration unit in California, you are REQUIRED to take steps to reduce air pollution. If you do not comply with these regulations, you could be one of the 50,000+ trucks to be banned in California. Cash penalties are currently being enforced by the state.

Trucks and buses, whether owned privately or by federal government, with a GVWR more than 14,000 lbs. must meet their particulate matter (PM) filter requirements and upgrade their engines to a 2010 model year (MY) or newer (refer to table A) by January 1, 2023! In addition, if you are selling a vehicle affected by these regulations, you MUST disclose this to any potential buyer. As well as “The Notice Advisory” must be printed with the bill of sale, contract or invoice. The proof of sale, out of state sale, export, removal or dismantling is required for a seller or buyer for 3 years and must be provided to CARB. Tom’s Truck Center provides all above requirements, professionally, and on time. We purchase all used trucks, running or not.

If you own a heavier vehicle, with a GVWR more than 26,000 lbs., you would have a slightly different schedule for replacement of your engines (refer to table B).
