All California-based fleets of two or more heavy-duty vehicles (gross vehicle rating over 14,000 pounds; except for 1998 and older, the rating is over 6,000 pounds) are required to perform annual smoke and tamper inspections of their fleet.

Beginning January 2010, diesel vehicles manufactured after 1997 with a gross vehicle weight rating (GVWR) of 14,000 pounds or less are included in the California Smog Check Program.  The Smog Check Program requires vehicles to receive a biennial Smog Check.  The Smog Check is required for the registration of the vehicle by the Department of Motor Vehicles (DMV) or for change of ownership.

1998 and newer diesel powered vehicle garaged in an air quality non-attainment area of the state with a GVWR of 14,000 pounds or less, are NOT subject to the requirements of the  PSIP any longer. They ARE subject to biennial smog check inspections.

1998 and newer diesel powered vehicle garaged in an air quality attainment area of the state with a GVWR of 14,000 pounds or less, are NOT subject to biennial smog check inspections but ARE required to have a passing PSIP inspection on a BIENNIAL BASIS.

1997 model year or earlier diesel powered vehicles with a GVWR between 6,000 and 14,000 pounds are still subject to the ANNUAL PSIP inspection and record keeping requirements.

Fleet owners are not required to inspect vehicles that are powered by diesel engines until their fourth model year (example: 2013 year engines must have their first test completed in 2017).

Smoke inspection and maintenance records must be kept by the fleet for two years. We provide electronic backup of your test records for this two year requirement at no charge.

The ARB randomly audits fleets, to examine smoke inspection and maintenance records and may test a representative sample of vehicles.
