Owners of natural gas vehicles (NGVs) and propane powered vehicles are required to pay an annual license fee, based on gross vehicle weight rating (GVWR), instead of motor fuel excise taxes. The fee is calculated as follows:
|Less than 10,000 pounds (lbs.)||$45|
|10,001 - 18,000 lbs.||$80|
|18,001 - 28,000 lbs.||$110|
|28,001 - 36,000 lbs.||$150|
|More than 36,000 lbs.||$250|
To determine the actual annual license fee imposed per registration year, multiply the appropriate dollar amount given in the above schedule by the motor vehicle fuel tax rate in cents per gallon effective on July 1 of the preceding calendar year, and divide the resulting amount by $0.12. There is an additional $5 handling fee for each license issued.
(Reference Revised Code of Washington 82.38.075)
AFVs powered exclusively by electric, natural gas, and propane vehicles are exempt from state emissions control inspections. Plug-in hybrid electric vehicles that obtain a U.S. Environmental Protection Agency fuel economy rating of at least 50 miles per gallon during city driving are also exempt from these inspections. (Reference Revised Code of Washington 46.16A.060)
Every alternative fuel automobile, truck, motorcycle, motor home, or off-road vehicle must bear a reflective placard from the National Fire Protection Association indicating that the vehicle is powered by an alternative fuel. Alternative fuels include propane and natural gas. (Reference Revised Code of Washington 46.37.467)
NEVs and medium-speed electric vehicles are defined as self-propelled, electrically powered four-wheeled motor vehicles. NEVs may reach speeds of at least 20 miles per hour (mph) but not more than 25 mph. Medium-speed electric vehicles may reach speeds of at least 25 mph but not more than 35 mph. NEVs and medium-speed electric vehicles must be in compliance with the national safety standards in Title 49 of the Code of Federal Regulations, section 571.500. NEVs are permitted on roads having speed limits of up to 35 mph. Medium-speed electric vehicles are permitted on roads having speed limits of up to 45 mph in counties consisting of islands that are only connected to the mainland by ferry routes. (Reference Revised Code of Washington 46.04.295, 46.04.357, 46.61.723, and 46.61.725)
Publicly and privately owned PEVs may charge at state office locations if the vehicles are used for state business, conducting business with the state, or as commuter vehicles. Additionally, contingent upon funding, the state must install electrical outlets suitable for charging PEVs in each of the state's fleet parking and maintenance facilities as well as every state-operated highway rest stop. The Washington Department of Enterprise Services may report to the governor and the legislature on the amount of electricity consumed and the number of PEVs using state-owned charging equipment if it represents a significant cost to the state. (Reference Revised Code of Washington 43.01.250, 43.19.648, and 47.38.075)
All-electric vehicle owners must pay an annual fee of $150 in addition to standard registration fees. Plug-in hybrid electric vehicles with an all-electric range of at least 30 miles are subject to a fee of $75. Hybrid electric vehicles are subject to a fee of $75. (Reference Revised Code of Washington 46.17.323-324)
The Washington Transportation Commission (Commission) studied the feasibility of transitioning from a fuel tax to a road user assessment system in the state. In 2012, the Commission conducted a limited scope pilot project to test the feasibility of this new system as it applies to PEVs. For the results of this evaluation, see the Washington State Department of Transportation report. The Commission began a year-long pilot project in fall 2017. On January 13, 2020, the Commission submitted a report of findings and recommendations to the governor, state legislature, and the U.S. Department of Transportation. The state legislature directed the Commission to further study aspects of the road usage charge program. For more information, see the Commission Road Usage Charge Assessment website.
A public PEV charging station is defined as a public parking space that is served by charging equipment. Public PEV charging stations must have vertical signage that identifies the station and indicates that it is only for PEV charging. The signage must be consistent with the U.S. Department of Transportation Federal Highway Administration's Manual on Uniform Traffic Control Devices.
By 2023, all public PEV charging stations must also display all charges and fees associated with operation. Any person who parks a vehicle in a public PEV charging station parking space and does not connect to the equipment is subject to a fine of $124.
By 2023, the Department of Agriculture must adopt rules requiring electric vehicle service providers (EVSP) to meet interoperability standards and offer multiple payment methods at public PEV charging stations. EVSPs must report inventory and payment information to the National Renewable Energy Laboratory annually. EVSE installed before January 1, 2024 are exempt from the rules until January 1, 2034.
Compressed, liquefied, and renewable natural gas used as a transportation fuel are exempt from public utility taxes. In addition, natural gas distribution businesses are eligible for an exemption for machinery and equipment used to produce natural gas for transportation fuel. This exemption is available quarterly as a remittance. (Reference Revised Code of Washington 82.08.02565 and 82.16.310)
The Washington State Department of Transportation (WSDOT) will develop a pilot program to provide AFV use opportunities to underserved and low-income communities and to those without easy access to transportation corridors. (Reference Revised Code of Washington 47.04.355)
