AB 620 California Assembly · 2025-2026 Regular Session

Medium- and Heavy-Duty Zero-Emission Vehicle Fleet Purchasing Assistance Program: rental vehicles.

Summary
Existing law establishes the Air Quality Improvement Program that is administered by the State Air Resources Board for purposes of funding projects related to, among other things, the reduction of criteria air pollutants and improvement of air quality. Existing law establishes the Medium- and Heavy-Duty Zero-Emission Vehicle Fleet Purchasing Assistance Program (program) within the Air Quality Improvement Program to make financing tools and nonfinancial supports available to operators of medium- and heavy-duty vehicle fleets to enable those operators to transition their fleets to zero-emission vehicles. This bill, for any regulation adopted to develop or implement the program, or other regulations that are regarding the procurement or use of medium- and heavy-duty zero-emission vehicles by a public or private fleet, would require the state board to consider specified things, including, among other things, the environmental and supply chain benefits of renting medium- and heavy-duty zero-emission vehicles compared to procuring them.

What changed between versions

09/08/25 - Enrolled AB620 · 2 edits
MINOR
No substantive policy changes between these two versions. The difference is purely presentational: the first version is the formal enrolled bill document with signatures and chapter formatting, while the second is a web page rendering of the same enacted text with navigation elements and metadata added.
TECHNICAL

The bill text was reformatted from a formal enrolled legislative document (with signature blocks, chapter number, and page headers) into a web page layout with site navigation, search tools, and metadata such as publication date and vote/appropriation flags. The actual statutory language of Section 44274.16 is unchanged.

A minor typo appears in the web version's short title line, which references 'Section 44276.16' instead of the correct 'Section 44274.16' used in the operative text. This does not affect the bill's substance.
