VMT fees are distance-based fees levied on a vehicle user for use of a roadway system. These fees are also known as mileage-based user fees or road usage charges. These fees differ from tolls because they are based on the distance driven on a defined network while tolls are facility specific and not necessarily levied on a per-mile basis. Generally, they are imposed on passenger vehicles only, although some states also impose them on trucks as well through a weight-mile program.
To date, this method of revenue has been implemented in Oregon beginning in 2015 and in Utah beginning in 2020. Other states are beginning to implement them as well. Oregon also runs a weight mile tax program.
The STSFA grants have been used by a number of states to run pilots and enhance programs. See report Surface Transportation System Funding Alternatives (STSFA) Program
A large number of publications on VMT fees are available throughout the Road Pricing website.
- Public Perception of Mileage-Based User Fees
(National Cooperative Highway Research Program) - This synthesis study presents a meta-analysis of
38 public opinion surveys on mileage-based user fees (MBUFs) conducted between 1995 and 2015. The study helps answer the questions of what is the public opinion on MBUFs; how does it vary by geography, demographics, and time; and
what are common themes, trends, and factors that influence public acceptance or rejection.
- Pilot Program Could Help Determine the Viability of Mileage Fees for Certain Vehicles
(Government Accountability Office) - Federal funding to build and maintain the nation's
highways and bridges comes primarily from highway users through federal fuel taxes. These revenues have eroded due to improvements in vehicle fuel efficiency and other factors contributing to shortfalls in the Highway Trust Fund.
Experts have proposed alternative means of raising revenues by charging drivers fees based on their miles traveled. Several states have tested systems that gather vehicle mileage and location data, which has raised privacy concerns.
GAO examined (1) the benefits and challenges of mileage fee initiatives in the United States and other selected nations, (2) mileage fee rates necessary to replace and supplement current Highway Trust Fund revenues and the effect
these fees would have on users' costs, and (3) state DOTs' views on future revenue demands and mileage fees. GAO reviewed five domestic pilot projects and programs in Germany, New Zealand, and the Netherlands; modeled mileage fees
for passenger vehicles and commercial trucks; and surveyed 51 state DOTs. GAO suggests establishing a pilot program to test the viability of such fees for commercial trucks and electric vehicles. FHWA should update its estimates
of road damages imposed by all vehicle types compared with the tax revenues generated by each. The Department of Transportation took no position on GAO's recommendation but provided technical comments which GAO incorporated as
- Mileage-Based User Fees for Transportation Funding: A Primer for State and Local Decision Makers
(Rand Corporation) Over
the past several decades, elected officials have grown increasingly wary of increasing motor fuel taxes, resulting in growing shortfalls in funding for surface transportation programs. Transportation funding shortfalls will grow
even more acute in the coming years as improved vehicle fuel economy and the adoption of alternative-fuel vehicles reduce federal and state fuel tax revenues by billions of dollars per year. With little prospect for near-term federal
action, some state decision makers, and even some local and regional officials, are beginning to explore a transition from taxing fuel to taxing vehicle miles of travel within their own jurisdictions. A system of mileage fees -
while challenging to design and implement and more costly to administer - would offer a significantly more stable source of funding in future decades and could support additional policy goals as well. This guide provides a brief
introduction to emerging mileage-fee design strategies for reducing system costs and building public support.
