Clean-Air Vehicles at a Fraction of the Price

The medium and heavy-duty vehicle market is transforming.
By slashing purchase costs, HVIP helps you be part of the transformation. HVIP's streamlined approach means you see the discount immediately at the point of sale. First come, first served. No scrappage. And dealers learn the voucher processing system, so there's less paperwork for you.

How to Participate

Get in on base vehicle price breaks from $20,000 to $240,000, depending on the vehicle you purchase. Whether you operate one vehicle or hundreds, HVIP dealers are ready to work with you. Individual owner-operators, small businesses, corporate leaders, school districts, and municipal fleets are all eligible. HVIP opened to its third wave of FY20-21 funding on October 28, 2021 at 10 a.m. Pacific. Wave 3 of FY20-21 funding has been fully requested.

Where to Find Incentive Amounts

The Vehicle Catalog lets you know the incentive amount for each vehicle. The Catalog only publishes the incentive amount per vehicle; the total cost of the vehicle will be determined between you and your dealer and noted in your Purchase Order. Also, Funding Tables are published in each edition of the Implementation Manual to further explain the amounts available for each specific technology and vehicle type.

Community Specific Incentive

Vehicles domiciled in Disadvantaged Communities (DACs) receive an increased incentive of 10%. For electric vehicles, that ranges from $4,500 to $15,000. DACs are Census-designated areas that are especially affected by air pollution due to geographic and socioeconomic factors. Enter your vehicle’s domicile address in the map below to determine eligibility for the DAC incentive. Addresses in the Pink zone or the Pink-Blue striped zone are eligible.

I would like to purchase an HVIP-eligible vehicle; how do I apply for a voucher?

Fleets / purchasers do not apply for HVIP vouchers directly. HVIP-eligible dealers are responsible for securing HVIP voucher funding through the online Voucher Processing Center. A purchaser should connect with an HVIP-approved dealer to acquire their vehicle and the dealer will take it from there to acquire the voucher. If you have a trusted dealer relationship or already have a vehicle in mind, connect us with your dealer and we can help them become HVIP-eligible.

Does the size of the fleet matter?

No, fleet size does not matter. Requirements and eligibility do not differ based on the size of the fleet.

Can I apply for more than one voucher?

Yes. Starting 2021, fleets may request up to 30 vouchers per calendar year. The cap for drayage fleets is set at 50 voucher requests per year.

I'm using an HVIP voucher to replace a vehicle; what happens to my old vehicle?

HVIP does not require scrappage of an old vehicle and does not have any requirements about what happens to replaced vehicles. For more information about truck replacement, visit CARB’s One Stop Truck site.

What vehicles are HVIP Eligible and how much do they cost?

HVIP eligible vehicles can be found in our Eligible Catalog. You can filter and search by vehicle type, manufacturer, vehicle size, and more. Incentive amounts per vehicle are the discount that a purchaser would receive. To know what the TOTAL price of the vehicle will be, contact one of our approved dealers. Our approved dealers will work out a price with you and then on your purchase order, there will be the HVIP incentive amount subtracted from the price that was negotiated.

What is the total cost of the vehicle I want to purchase?

The HVIP vehicle catalog only publishes the incentive amount per vehicle; the total cost of the vehicle will be determined between you and your dealer and noted in your Purchase Order.

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

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. HVIP is part of the California Climate Investments, a statewide initiative that invests Cap and Trade dollars.

What does first-come, first-served mean?

Vouchers are awarded on a first-come, first-served basis. Funding is set aside immediately at the point of the 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.

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 Investment 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 at the pink and pink/blue sections, on this website.
