Legislators failed earlier this year to approve a transportation funding package. Hundreds of state workers’ jobs are in limbo, and the proposal for a road usage charge for EV drivers was left on the table.

Hawaii in 2023 was the first state to create a mandatory road usage charge program to make up for projected decreases in fuel tax revenue due to the growing number of electric, hybrid and fuel-efficient cars. Many other states have studied the concept, and Oregon, Utah and Virginia have voluntary programs.

The concept has promise as a long-term funding solution, experts say. Others worry about privacy concerns and discouraging people from buying EVs, which can help reduce transportation emissions.

“This is a pretty major change,” said Liz Farmer, an analyst for The Pew Charitable Trusts’ state fiscal policy team, noting “the challenge in enacting something that’s dramatically different for most drivers.”

Oregon’s transportation woes

Oregon’s transportation department says the budget shortfall stems from inflation, projected declines in gas tax revenue and other spending limits. Over the summer, it sent layoff notices to nearly 500 workers and announced plans to close a dozen road maintenance stations.

Democratic Gov. Tina Kotek paused those moves and called the special session to find a solution. Republican lawmakers say the department mismanaging its money is a main issue.

Kotek’s proposal includes an EV road usage charge that is equivalent to 5% of the state’s gas tax. It also includes raising the gas tax by 6 cents to 46 cents per gallon, among other fee increases.

The usage charge would phase in starting in 2027 for certain EVs and expand to include hybrids in 2028. Should the gas tax increase be approved, EV drivers either would pay about 2.3 cents per mile, or choose an annual flat fee of $340. Drivers in the program wouldn’t have to pay supplemental registration fees.

Drivers would have several options for reporting mileage to private contractors, including a smartphone app or the vehicle’s telematics technology, said Scott Boardman, policy adviser for the transportation department who works on the state’s decade-old voluntary road usage charge program.

As of May, there were over 84,000 EVs registered in Oregon, about 2% of the state’s total vehicles, he said.

Hawaii launches program

Under Hawaii’s program, which began phasing in last month, EV drivers can pay $8 per 1,000 miles driven, capped at $50, or an annual fee of $50.

In 2028, all EV drivers will be required to enroll in the pay-per-mile program, with odometers read at annual inspections. By 2033, the program is expected to expand to all light-duty vehicles.

Questions about privacy and fairness

In past surveys commissioned by Oregon’s transportation department, respondents cited privacy, GPS devices and data security as concerns about road usage charges.

Oregon’s voluntary program has sought to respond to such concerns by deleting mileage data 30 days after a payment is received, Boardman said. While plug-in GPS devices are an option in the program, transportation officials anticipate moving away from them because they’re more expensive and can be removed, he added.

Still, not everyone has embraced a road usage charge. Arizona voters will decide next year whether to ban state and local governments from implementing a tax or fee based on miles traveled after the measure was referred to the ballot by the Republican-majority Legislature.

Many people don’t realize that “both your vehicle and your cellphone capture immense amounts of data about your personal driving habits already,” said Brett Morgan, Oregon transportation policy director for the nonprofit Climate Solutions.

Morgan added that road usage charges exceeding what drivers of internal combustion engines would pay in gas taxes could dissuade people from buying electric and hybrid cars. Already, federal tax incentives for EVs are set to expire under the tax and spending cut bill recently passed by the GOP-controlled Congress.

“We are definitely supportive of a road usage charge that has EVs paying their fair share, but they should not be paying extra or a penalty,” Morgan said.
