Voucher Incentive Program


NEW! The 2023 Voucher Incentive Program is currently closed.
Please check back in early 2024 when we plan to reopen VIP!

VIP Overview:

The VIP is a streamlined approach to reduce emissions by replacing old, high-polluting vehicles with newer, zero-emission vehicles. This program is limited to owners/operators with fleets of 10 or fewer vehicles that have been operating at least 75% (mileage-based) in California during the previous twenty four (24) months.

The goal of this program is to reduce emissions from in-use heavy-duty trucks in small fleets by replacing Engine Model Years 2017 and older with zero-emissions compliant models. The VIP is implemented by South Coast AQMD through contractual agreements with Dealers and Dismantlers. The Dealers will apply to South Coast AQMD for the vouchers on behalf of the applicant. If approved, the voucher amount will be deducted from the total purchase price of the truck by the Dealer.

Applicants interested in replacing their truck must purchase their replacement truck through a South Coast AQMD-approved VIP Participating Dealership that has completed the required training for the VIP.  A current list of South Coast AQMD approved Dealerships and Dismantlers is included below. Additional updates to these lists will be posted on our webpage as they become available.

Program Highlights:

  • First-Come, First-Served Basis (no application deadline; open until funds are exhausted)
  • Rapid Response Time: Applicant is notified within 20 business days of submitting application for funding
  • Exclusively for small fleets (10 or fewer trucks)
  • Maximum of $410K available for Zero-Emission (ZE) replacement trucks
