History
Oregon established the Road User Fee Task Force (RUFTF) in 2001 to explore alternatives to fuel tax. The RUFTF still exists to advise legislators on progressing the state's RUC programme, and its current and a little of its historic work is available here.
Oregon Department of Transportation (ODOT) research led to the first Oregon pilot, the Road User Fee Pilot Program, which ran in 2006–2007. The pilot focused on charging light vehicles more fairly for road use. It tested purpose-built, GPS-enabled on-board units and a “pay at the pump” model. Vehicles exchanged mileage data with equipment at petrol stations, allowing road-use charges to be calculated and state fuel tax to be deducted automatically. It also included a time-of-use/congestion charge option, by allowing some participants to select paying a lower per mile fee off-peak and driving outside Portland metro region, but with a higher per mile fee for driving within Portland during peak periods.
The congestion pricing element went nowhere, as it indicated mixed objectives, but was still early and useful research into how people might respond to such price signals.
The report is here. The pilot was informative as it tested bespoke GPS enabled vehicle technology and the pay at the pump model, and was found wanting. A key issue being the cost of retrofitting gas stations to receive data from vehicles about mileage, and to discount gas tax from fuel bills. More importantly, a "pay at the pump" model was seen as useless for EVs, and wouldn't provide an answer. So Oregon embarked on a different approach.
A second pilot, the Road Usage Charge Pilot Program, ran in 2012–2013. It tested an “open system” with multiple mileage-reporting methods and private-sector providers, laying the groundwork for OReGO’s launch in July 2015. That report is published here. (disclaimer, I provide a small piece of advice on that report),
The result of that program was that legislation was enacted to implement the existing OReGO program (Senate Bill 810 - (2013)) - a voluntary operational RUC program for owners of EVs, PHEVs and other highly fuel efficient light vehicles. It has been amended over time, but today it works as follows.
OReGO
Eligible vehicles are passenger vehicles with a gross vehicle weight rating of 10,000 lb or less (about 4.5 tonnes) that are fully electric, plug-in hybrid (PHEV), or have a combined fuel economy rating of at least 40 miles per US gallon (mpg).OReGO offers a choice of such vehicle owners between paying RUC at a rate of US$0.02 per mile (to be billed monthly) or a higher registration fee every two years.
Participants whose vehicles use gasoline receive fuel-tax credits against their RUC liability, which is calculated on a per-mile gallon basis, based on the vehicle's official fuel efficiency rating.
Vehicles owners who do not join OReGO are currently subject to the following registration fees for a two-year period:
- EVs: US$316
- PHEVs: US$224
- High efficiency vehicles: US$136
Those that do join OReGO only pay US$126 for two years in registration fees, plus RUC. Clearly, while RUC may be attractive to some EV owners, it has little appeal to owners of high efficiency vehicles who face a saving of US$10 over two years in exchange for US$0.02 for every mile driven over that time. After 500 miles of driving, the saving is lost. For EVs it is 9,500 miles over two years before the saving is lost. Unlike Utah, Virginia and Hawai’i, Oregon does not cap RUC payments to the fixed fee.
OReGO offers three mileage-reporting options:
- Odometer image capture: Owners periodically submit an odometer photograph through an app or online portal. All reported miles are charged.
- Plug-in device: A GPS-enabled device connects to the vehicle’s data port and automatically excludes out-of-state and off-public road mileage.
- Native vehicle telematics: Telematics built into the vehicle at manufacture is used, if available, to measure and transmit mileage data.
Miles driven outside Oregon or off public roads are legally exempt. GPS-enabled options exclude eligible mileage automatically; other users have to submit declarations as to the extent of off-road mileage, when and why, to obtain a refund.
Geotoll and NextPassMiles (Cintra) are the current suppliers of systems and accounts for the Oregon system.
Low takeup of RUC
Originally OReGO was capped at a maximum of 5,000 participants, but that cap was lifted in 2017. Regardless, the number of vehicles enrolled in OReGO has been much lower, with around 1,000 vehicles enrolled at present. This compared with over 140,000 EVs being registered in Oregon, and a total of over 350,000 vehicles eligible to be enrolled in OReGO.
The reasons for this are mixed. Clearly the difference between RUC and the savings on registration are not significant for many users, especially with the simplicity of choosing a fixed fees and forgetting about it. Another factor has been the complexity of joining OReGO when a vehicle is first registered. Typically owners register the vehicle upfront, paying the higher fee, then would have to choose to join OReGO after two years by their own initiative. Few have.
Next steps
House Bill 3991, enacted in 2025, introduces a phased requirement for eligible owners to choose between RUC and a higher fixed registration fee:
- 1 July 2027: Existing EV owners must make an explicit choice at their next registration renewal: US$340 for two years, or RUC of US$0.023 per mile plus a US$126 two-year registration fee.
- 1 January 2028: Owners of new EVs must choose between the higher fixed registration fee and RUC when first registering their vehicle.
- 1 July 2028: Owners of new and existing PHEVs and other vehicles rated at least 40 mpg, including qualifying conventional hybrids, must choose between the higher fixed registration fee and RUC of US$0.023 per mile. The two-year fixed fees will be US$284 for PHEVs and US$196 for other high-efficiency vehicles.
RUC itself remains optional, making a choice becomes mandatory. Owners must choose at each two-year registration renewal.
Oregon is therefore moving from a low-profile opt-in programme to a mandatory-choice model. Many owners are expected to retain the fixed fee, but the more explicit choice is expected to increase RUC uptake.
The effect of this should be a much higher take-up of OReGO, as it becomes easier to sign up participants, and the economics of shifting to RUC are attractive to a higher proportion of vehicle owners. Some reports indicate that it is mandating all such vehicles to move to RUC, which while strictly true, this is only because the higher fixed fee is being called part of the RUC program.
It will NOT be mandatory to pay per mile, just mandatory to be part of the program.
For Oregon this is all a great step forward, but after July 2028 it will beg further questions. If RUC does not increase in popularity will it become mandatory for some vehicles (by distance), or will the higher registration fee be increased even more to incentivise a greater shift to RUC?
I won't be too bullish, because it has taken some years to get to at least this point for Oregon.
