On-Road Heavy-Duty Voucher Incentive Program (VIP)

The On-Road Heavy-Duty Voucher Incentive Program (VIP) provides funding opportunities for fleet owners with 10 or fewer vehicles to quickly replace, their older heavy-duty diesel or alternative fuel vehicles. The goal of the voucher program is to scrap and replace older, higher polluting vehicles earlier than would have been expected through normal attrition or by regulation. Fleet owners that operate vehicles with 2009 or older model year diesel or alternative fuel engines may be eligible for funding towards the purchase of a replacement vehicle that has a 2013 or newer engine.
