Requirements for Diesel Trucks in California As of Jan 1st

California Emission Reduction

Requirements for Diesel Truck and Equipment Owners

All owners of diesel trucks, buses, trailers and transport refrigeration units, or "reefers," that operate in California, are required to take steps to reduce air pollution. Reducing emissions from existing equipment is necessary to meet federally imposed clean air standards and to reduce the adverse health effects from pollution. Funding opportunities may also be available to lower emissions earlier than required. This document summarizes requirements and key dates for upgrading existing equipment:

Idling Limits restrict diesel vehicles from idling more than five minutes, and idling in school zones is not allowed with limited exceptions.

The Heavy-Duty Vehicle Inspection Program uses random roadside inspections to verify that diesel engines do not smoke excessively and are tamper free.

Emission Control Labels must be affixed to engines of all commercial heavy-duty diesel vehicles, and must be legible as proof the engine, at minimum, meets U.S. federal emissions standards for the engine model year.

The Periodic Smoke Inspection Program requires owners of California based fleets of two or more diesel vehicles to perform annual smoke opacity tests and to keep records for at least two years for each vehicle. The requirement does not apply to cars or trucks that must undergo a Smog Check.

HEAVIER VEHICLES with a GVWR more than 26,000 lbs. need engine upgrades as shown in the schedule below (no reporting is required).

Schedule for Heavier Trucks and Buses

LIGHTER VEHICLES with a GVWR 26,000 lbs. or less need to be upgraded to 2010 model year engines or to newer models as shown in the table. No retrofit PM filters or reporting is required. Engine Year PM Filter* 2010 MY Engine
