Voucher Incentive Program


The Voucher Incentive Program is currently not accepting applications.
Please visit us again as VIP will re-open in early 2023.

VIP Overview:

The VIP is a streamlined approach to reduce emissions by replacing old, high-polluting vehicles with newer, lower-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 2009 and older with Engine Model Years 2013 (or newer) 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 an 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 15 business days of submitting application for funding
