How to Participate

We make it easy for you to close the deal. Become an eligible dealer and offer your customers point-of-sale price breaks with funding set aside at the time a voucher is requested. Training is required on an individual basis for each person who makes HVIP sales representing a dealership or Original Equipment Manufacturer. Additional HVIP funds are anticipated to be available for request in the first part of calendar year 2022. HVIP dealer training will become available following the publication of the FY1-22 Implementation Manual in 2022.

Group dealer training phone calls will be set up between the HVIP dealer trainer and prospective HVIP dealers following the completion of the items listed in Step 3 and is an opportunity for the dealer to confirm their understanding of the HVIP rules and requirements and ask questions about the VPC. The training call will be made available in 2022.

How the Voucher Process Works


Dealer completes the Voucher Request Form in the Voucher Processing Center when they have a valid Purchase Order completed for an HVIP-eligible vehicle. The voucher discount must be passed on to the purchaser at the time of the sale.
Remember that unless granted CARB approval, each manufacturer may have no more than 100 unredeemed vouchers at any time, regardless of how many dealers are affiliated.


Voucher Request Form is reviewed by HVIP staff, who will contact the Dealer if any information is missing. Then, Dealer and Purchaser will sign the Terms and Conditions Form.


After the vehicle is delivered to the purchaser, the dealer will complete the required items on the Redemption Checklist in order to redeem the voucher. A voucher is valid for 18 months from the date of the request and must be renewed every 90 days once approved.


Once delivered and all paperwork is turned in, the dealer receives a check in the mail for the total voucher amount!

Manufacturer Resources

The FY20-21 Implementation Manual has been released, and changes to eligible vehicle incentive amounts will not warrant updated Approval Letters.
Also, 0.02 g/bhp-hr internal combustion engines have graduated from HVIP eligibility, however engines certified to the optional low NOx standard of 0.01 g/bhp-hr may be eligible for HVIP incentives.

Telematics Requirement

The quarterly telematics reporting process is required from manufacturers for 3 years after a voucher is redeemed.

Key Documents


I represent a dealership. How do I apply for a voucher?

Dealers must be HVIP-approved to be able to submit voucher requests on behalf of their customers. Any dealer or manufacturer who sells HVIP-eligible technologies should reach out to to begin the training process.

I was HVIP-certified in a past year; am I still an eligible dealer?

A Voucher Processing Center (VPC) account may be deactivated if a dealer has not logged in for over 365 days. If you believe your VPC login has been deactivated, please reach out to The program administrators will likely require that you pass the HVIP Dealer Quiz before your eligibility status is updated.

I’m having trouble accessing the Voucher Processing Center, what should I do?

You should reach out to A VPC account may be deactivated if a dealer has not logged in for over 365 days. We can help you restore access.

What paperwork is needed throughout the voucher request and redemption processes?

To submit a voucher request, an eligible dealer needs only a Purchase Order that makes clear that HVIP funding would be applied. The documents needed for redemption of an HVIP vehicle voucher can be found in the HVIP Voucher Redemption Checklist.

How do I know if funds are secured?

When HVIP is open to requests, the dealer and purchaser will be notified via email when a voucher request has been submitted, and whether funding is set aside for the request or whether funding is unavailable due to first-come first-served demand. Then the initial review of the voucher by the Voucher Processing Center team will start.

My co-worker is an HVIP approved dealer, can I use his or her Voucher Processing Center login? 

No, you cannot. There should be no sharing of VPC logins within a dealership. Up to three individuals at dealerships can become HVIP-trained: this would allow for multiple individuals to sign off on paperwork for the same voucher and would allow for each dealer to submit and track voucher requests on the VPC.

It is strongly recommended that a dealership/organization dedicate one person to understanding HVIP’s policies/procedures/processes rather than multiple people.  Organizations with one HVIP point-person experience less issues brought to CARB’s attention, repeat offenses and voucher cancelations.

What happens if a vehicle is delivered/titled/paid for ahead of a voucher request being submitted?

It is against HVIP policy to provide funding for vehicles that are delivered/paid for ahead of voucher request. If a vehicle is paid for/delivered ahead of voucher request, the vehicle dealer and purchaser can appeal to CARB to allow for an exception. Please contact for more information.

How does a vehicle become HVIP-eligible? 

Vehicle eligibility is handled by the California Air Resources Board. Please contact for more information.

Is retrofitting eligible for funding?

Yes, conversions of trucks and buses from internal combustion to hybrid and zero-emission can be funded through HVIP. Please refer to the FY20-21 Voucher Funding Table for more information.

What is the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP)?

HVIP was created to reduce price barriers, enabling fleets to adopt more clean heavy-duty commercial vehicles. Created by the California Air Resources Board (CARB) in 2009, HVIP provides point-of-sale discount vouchers that reduce the purchase cost of vehicles operated in the State of California. HVIP vouchers make zero-emission and Low NOx buses and trucks as affordable as their traditional fossil-fueled counterparts at point of sale and reduce prices for medium- and heavy-duty hybrid vehicles. Funded vehicles include parcel, beverage, and food-distribution trucks, transit buses, shuttle buses, and more.

Why did CARB create HVIP?

The goal of HVIP is to accelerate and facilitate the adoption of low-emitting hybrid, low NOx, and zero-emission trucks and buses. These vehicles are relatively new technologies and are therefore more expensive than traditional vehicles, especially in the early market years when production volumes are low. CARB recognizes that these vehicles have the proven ability to reduce criteria and greenhouse gas (GHG) pollutants in California and aims to accelerate the penetration of these cleaner vehicles to help meet state clean air regulations and climate change goals.

What does first-come, first-served mean?

Vouchers are awarded on a first-come, first-served basis. Funding is set aside at the point of a voucher request. This means that there is no uncertainty regarding securing funding, and no lengthy application or bid process. HVIP is a streamlined funding mechanism that is set up for ease of use by end-users. Dealers, not purchasers, are responsible for securing HVIP funding – fleet owners do not need to gain an understanding of the voucher process to receive the full benefits of HVIP funding. A list of participating dealers can be found in the HVIP Eligible Vehicles Catalog.

How can I be notified of HVIP news and events?

Sign up for the California HVIP e-mail list by filling out the form: Contact Us.

Who can I contact for more information?

Please email or call the HVIP toll-free hotline at 888-457-HVIP.

How do we know how much money is available?

The ticker at the top of the home page lists how much money remains available to be requested, if any. This reflects the real-time funds, based on the vouchers requested to-date.

How do I know if a vehicle is eligible for HVIP?

All HVIP-eligible vehicles can be found in the clean vehicle catalog. If you think a vehicle is eligible, but do not see it listed, please send an email to

How much are the vouchers worth?

CARB recognizes that battery size is the largest determinant of battery-electric vehicle cost, therefore HVIP has simplified the voucher tables to one single voucher table based on vehicle weight rating. The incentive amounts are accompanied by voucher modifiers to support unique fleets (public transit and school districts) as well as costlier vehicle bodies. 

Can HVIP voucher funding be combined with other funding (grants, incentives, etc.)?

Yes, however the ability to combine funding sources may be considered on a case-by-case basis. Please contact for more information.

Generally, local and federal funds can be stacked with HVIP, while stacking HVIP with state-funded incentives is NOT permitted, except for public transit buses. This includes stacking with other California Climate Incentive programs.

For public transit buses, HVIP will fund the remaining cost up to the maximum voucher amount after the other incentives have been applied at their maximum allowable amounts.

The total voucher amount (base incentive plus voucher enhancements), plus all other eligible public incentives, may not exceed 90 percent of the total vehicle cost for purchases by private entities, and 100% for purchases by public entities.

Are light-duty vehicles eligible for HVIP?

No, they are not. The Clean Vehicle Rebate Project provides incentives for the purchase or lease of new, eligible zero-emission vehicles, including electric, plug-in hybrid electric, and fuel cell vehicles.

What is a Disadvantaged Community (DAC)? How can I determine eligibility for a DAC “Plus Up”?

A DAC is a Census-designated area that is especially vulnerable to the impacts of climate change because of socioeconomic and geographic factors. HVIP provides increased incentives for fleets domiciled within disadvantaged communities. The value of this “plus up” varies by vehicle type and increases for larger vehicles. To determine if a vehicle qualifies for a DAC “Plus Up” (increased funding), enter the domicile address in the address search bar, and look for the pink or pink/blue sections, on CARB’s website.

Where can I learn about HVIP policy changes for FY 2020-21?

Answers to frequently asked questions for Fiscal Year 2020-21 can be found in the FY20-21 Implementation FAQs.
