**Scale and Impact**
Since its launch in 2009, HVIP has provided over
**$750 million**
in funding to
**2,000+ fleets**
, helping put
**10,000 zero-emission vehicles**
on the road. These vehicles have collectively logged more than
**340 million miles**
without diesel exhaust, cutting greenhouse gases and improving air quality in frontline communities.


**Voucher Amounts and Add-Ons**
Base Incentives Range From $7,500 For Smaller Vehicles (Class 2b) To $120,000 For Heavy Class 8 Trucks And Buses. Several Modifiers Can Boost These Values



- Small fleets: up to 100% increase (currently capped at five vouchers per entity).
- School buses: 65% increase.
- Drayage and refuse vehicles: 25% increase.
- Fuel-cell Class 8 trucks: eligible for full coverage of cost.

**Eligibility Shifts**
CARB has begun refining who can access HVIP funds. As of
**January 1, 2025**
,
**private fleets with 50 or more vehicles**
are
**ineligible for new voucher requests**
. This move shifts the focus toward
**small operators and public fleets**
, ensuring smaller businesses aren’t crowded out by larger corporations. Vouchers already issued to big fleets remain valid.


**Funding Availability**
Demand has surged. Between 2023 and 2024, voucher redemptions climbed
**177%**
, exhausting most funding pools early in 2025. Only specific set-asides remain open, such as allocations for
**transit agencies**
and the
**Innovative Small E-Fleets (ISEF) program**
. CARB expects some cancellations to free up limited funds later in the year. Meanwhile, the
**FY 2025-26 Clean Transportation Funding Plan**
is under development, with workgroups scheduled for summer 2025 to decide on new allocations and rule updates.


HVIP is a proven success story, but its popularity has outpaced available dollars. Right now, opportunities are narrow and mainly targeted at small fleets and public transit agencies, with broader funding expected to re-open once the new fiscal year plan is approved.
