Joint Transportation Committee


​Design of Infrastructure and Incentive Program for Medium and Heavy-Duty Zero Emission Vehicles (MHD ZEVs)

​​The 2023-25 Transportation Budget The 2023-25 Transportation Budget (Sec. 204 (5)) directs the JTC to oversee a project to:

  • Design and document an infrastructure and incentive strategy to drive the purchase and use of zero emission medium and heavy-duty vehicles, as well as cargo handling and off-road equipment, in the state including, but not limited to, programs for tractor trucks, box trucks, drayage trucks, refuse trucks, step and panel vans, heavy and medium-duty buses, school buses, on and off-road terminal tractors, transport refrigeration units, forklifts, container handling equipment, airport cargo loaders, and railcar movers. The strategy design must include an implementation plan documenting the steps to roll out the vehicle and infrastructure incentive programs.
  • Conduct a review of the passenger vehicle tax incentive in current Washington state law and evaluate its utility.​

The Consultant will engage stakeholders to hear directly on incentive strategies that could help overcome barriers to replacement of internal combustion MHD vehicles with ZEVs.

For this study the JTC has contracted with a consulting team led by CALSTART. The final report is due to the transportation committees of the legislature by January 2, 2024.​
