The Prop. 1B Program offers a financial incentive to owners/operators of eligible equipment involved in goods movement operations to upgrade their equipment, install electrical infrastructure at a truck stop or distribution facility, or implement other projects that will reduce diesel air pollutant emissions. The types of goods movement equipment targeted by the Prop. 1B program include: heavy-duty diesel trucks (replacement or repower), transportation refrigeration units (TRU) truck stop or distribution center electrification infrastructure, locomotives, ships at berth (e.g., shore power), commercial harbor craft, and cargo handling equipment at ports or rail yard facilities.

The voucher incentive program is restricted to fleets comprised of 10, or fewer, diesel-fueled trucks, with an emphasis on fleets of three or fewer, and is open to trucks with a GVWR greater than 14,000 pounds. Applications will be reviewed and approved on a first-come, first-served basis (based on the date of receipt by the District) until funds are exhausted.
