How It Works
Getting Started
Eligible transit agencies interested in participating should identify an HVIP-eligible bus from the vehicle catalog to purchase, contact the HVIP-approved dealer affiliated with that bus, and work with the dealer to create a purchase order. The purchase order must include the HVIP incentive amount by which the price of the vehicle is reduced.
