Clean Truck & Bus Vouchers (HVIP)
HVIP continues to accelerate market transformation by incentivizing the purchase of zero-emission medium- and heavy-duty trucks and buses for California fleets. HVIP is the cornerstone of advanced technology incentives for commercial medium- and heavy-duty vehicles, providing funding since 2010 to support the long-term transition to ZEVs, as well as supporting investments in other emerging technologies to achieve substantial GHG reductions and help meet health-based ambient air quality standards. Investments made through HVIP provide both broad purchase incentives for fleets, and more targeted measures to address air quality needs in California’s priority populations. Voucher incentives complement other programs in CARB’s medium- and heavy-duty funding portfolio by providing a streamlined application process without requiring the scrappage of an existing vehicle.
