AB 1944 California Assembly · 2025-2026 Regular Session

Zero-emission transit buses: axle weight.

Summary
Existing law prohibits the maximum gross weight on any one axle of a bus from exceeding 20,500 pounds, except the maximum limit for the curb weight on any one axle of a transit bus procured through a solicitation process pursuant to which a solicitation was issued on or after January 1, 2019, is set at 22,000 pounds. Existing law, notwithstanding the previous provisions, sets specified higher maximum limits up to 25,000 pounds for the curb weight on any one axle of an articulated transit bus or zero-emission transit bus procured through a solicitation process pursuant to which a solicitation was issued during specified periods between January 1, 2016, and December 31, 2021, inclusive, and sets the 22,000-pound maximum limit for an articulated transit bus or zero-emission transit bus procured through a solicitation process pursuant to which a solicitation was issued on or after January 1, 2022. A violation of this provision is a crime. This bill would, until January 1, 2032, establish specified higher weight limitations up to 25,000 pounds for zero-emission transit buses procured through a solicitation process pursuant to which a solicitation was issued at various specified periods between January 1, 2027, and December 31, 2031 inclusive.
