APCD - On-Road Grants 2017


The fleet modernization program provides incentives to replace old high pollution medium and heavy duty vehicles with newer, lower emission replacement vehicles, providing real emission benefits earlier than would have been expected attrition or regulation implementation.

Eligibility Criteria

  • Existing vehicle must have an engine of model year 2006 or older. Existing old school buses may have an engine of any model year.
  • Existing vehicle must meet the criteria for either a Medium-Heavy Duty or Heavy-Heavy Duty vehicle as defined in the 2011 CMP Guidelines.
  • The existing vehicle must be in operational condition, currently registered in California for the past 24 months and in compliance with federal, state and local regulations.
