As Washington Drags Its Feet, States Take the Lead on Mileage Fees
Oregon, true to its history as the first state to implement a gas tax, was also the first state to consider getting rid of it — in exchange for adopting a mileage-based system for highway funding. And the Beaver state isn’t alone: A number of other states have done studies and introduced legislation to charge drivers for the distance they travel instead of the gasoline they consume.

To date, none of the states have passed legislation to enact a vehicle miles traveled (VMT) fee. But with an increase in the federal gas tax seemingly impossible in an election year and federal funding increasingly uncertain, states may well be left with little alternative but to reconsider an idea many experts agree makes sense.
With Americans driving less and opting for more fuel-efficient cars, revenues from state gas taxes have been on the decline. Data from the Federal Highway Administration show that between 2007 and 2008, 30 of 50 states experienced declines in their gas tax receipts, dropping by an average of two percent. If electric cars one day replace America’s internal combustion fleet entirely, revenues based on gas taxes could dry up altogether.
For many states, VMT fees may be just what the doctor ordered. While the prospect of a mileage-based system has led some to argue that the GPS technology needed to make it work optimally is an invasion of privacy, there is a growing consensus that it is a much more sustainable option for transportation funding. Earlier this year, the Congressional Budget Office issued a report stating that the VMT fee system is a feasible transportation funding option and would result in a more efficient use of the highway system. This follows several earlier reports, including from two federal transportation financing commissions, recommending that the federal gas tax be gradually replaced with VMT fees [PDF].
In the past decade, about two dozen states have examined the feasibility of such a system. Here are some of the more noteworthy initiatives:
Oregon: Having learned valuable lessons from its original VMT pilot program in 2007, Oregon transportation officials redesigned the ways that vehicle mileage is recorded and fees are collected in a Phase II pilot program this year. Instead of a pay-at-the-pump concept, the state’s Road User Fee Task Force proposed legislation (HB 2328) based on an “open technology” platform applied only to drivers of electric and plug-in hybrid vehicles.
The original pilot program exposed design shortcomings and significant public opposition to the mandatory use of GPS technology to track vehicle miles traveled, so the new proposal would give Oregon’s DOT the flexibility to establish multiple methods for reporting VMT. An “opt-in” feature would allow drivers to choose the method by which they report their mileage and pay their fees. The revised concept also envisions a larger role for the private sector in the data collection and management of accounts.
