The state trucking industry is calling on the Legislature and Gov. Jay Inslee to detach Washington state from a California-based electric vehicle program due to a variety of practical and logistical factors that they argue threaten the supply chain system. Under California’s Advanced Clean Trucks program, the trucking industry must progressively transition to zero emissions for medium and heavy-duty trucks. Starting next year, zero emission vehicles must make up 7% of all Class 2b-3 truck and Class 7-8 tractor sales, while Class 4-8 truck sales must be 11% zero emission vehicles.
