Truck and Bus Regulation
The Truck and Bus regulation has been in effect since December 2008 and we are now in the last replacement phase of the regulation with a final deadline of January 1, 2023, to upgrade to 2010 or newer model year engines. Please submit any compliance documentation by emailing a scanned copy or photos of your documents to trucrs@arb.ca.gov. Include your TRUCRS ID number, a detailed description of the request, and list any applicable VIN(s). Please do not mail hard copy documentation unless requested by staff. Faxing of documentation is no longer available.
