Road Usage Charge Assessment
In 2012, the Legislature directed the Transportation Commission, in close cooperation with WSDOT and with guidance from a multi-stakeholder steering committee, to conduct an assessment of Road Usage Charging and determine if it is feasible. Road Usage Charging (RUC) is the notion of charging users of the road system a per mile charge, as opposed to our current system in which we pay for our roads via a gas tax that is assessed on a per gallon basis at the time we purchase our fuel.
