Bill overview
This bill changes the frequency of inspections for large, non-gasoline trucks in California. It limits required testing to every two years for vehicles deemed ‘low use,’ meaning those driven less than 1,000 miles annually. The California Air Resources Board will create rules to determine which vehicles qualify as ‘low use’ and implement this new testing schedule. This aims to reduce the burden of inspections on vehicles with lower mileage.
Key provisions
- Limits heavy-duty vehicle inspections to biennially (every two years).
- Applies to nongasoline heavy-duty onroad motor vehicles with a gross vehicle weight rating of more than 14,000 pounds.
- Defines ‘low use’ as vehicles driven fewer than 1,000 miles per year in California.
- Requires the State Air Resources Board to develop rules for implementation.
Who is affected
- Trucking companies
- Vehicle owners and operators of heavy-duty vehicles
- The California Air Resources Board
Notable changes
- Changes the current inspection frequency from annual to biennial for low-use vehicles.

LEGISLATIVE COUNSEL'S DIGEST
SB 1064, as amended, Dahle. Heavy-Duty Vehicle Inspection and Maintenance Program: biennial testing.
Existing law generally designates the State Air Resources Board as the state agency with the primary responsibility for the control of vehicular air pollution. Existing law requires the state board to develop and implement a Heavy-Duty Vehicle Inspection and Maintenance Program for nongasoline heavy-duty onroad motor vehicles with a gross vehicle weight rating of more than 14,000 pounds. Existing law requires that the program include, among other things, test procedures for different motor vehicle model years and emissions control technologies that measure the effectiveness of the control of emissions of oxides of nitrogen and particulate matter. Existing law requires, as part of the program, the state board to develop a Heavy-Duty Vehicle Inspection and Maintenance Compliance Certificate. Existing law requires the state board to issue the certificate to the legal owner, registered owner, or designee of a vehicle that, at the discretion of the state board, meets the requirements of the program so that vehicle owners and operators may easily demonstrate proof of compliance for specified purposes.
This bill would limit specified testing of all nongasoline heavy-duty onroad motor vehicles with a gross vehicle weight rating of more than 14,000 pounds that are considered low use, as defined to not more frequently than biennially. annually. The bill would require the state board to adopt rules and regulations to implement this provision.
