Senate Vote on Transportation Bill Delayed Until September 29

The final steps for Oregon’s 2025 Special Legislative Session have been delayed until September 29. While the House passed HB 3991A, a revenue bill, and HB 3992, a budget bill, on September 1, the Senate has been unable to hold a floor session due to the prolonged illness of Senator Chris Gorsek (D-Troutdale). A Senate floor vote was scheduled to occur September 17. Since HB 3991 is a revenue bill, the Senate needs 18 votes, and without a Republican Senator willing to support the bill, Senate leadership needs every Democratic member to reach 18 “yes” votes.  

What Does HB 3991A Do?

The transportation funding package includes the following:

1)  The bill increases the state gas tax by $0.06, registration fees by $42, and title fees by $139, which combined will generate an additional $350 million annually for the State Highway Fund (SHF). The SHF will follow the 50-30-20 shared revenue formula, with cities and counties receiving 50% percent of the revenue generated. By FY 2026, cities should see an increase of 25-30% from their current SHF distribution.

  • The Small Cities program will see an increased grant fund of $1 million in 2028 for a total of $6 million/year.
  • The Small County Fund will also see an increase.

2)  Electric vehicles and hybrid vehicles will be subject to a road-user charge (RUC) based on vehicle miles driven. The RUC will be set at 5% of the per/gallon fuel rate ($0.023/mile). 

  • Electric vehicles – 2027, road user charge, or annual opt-out fee of $340
  • Hybrid vehicles – 2028, road user charge, or annual opt-out fee of $340. Note: By joining this program, hybrid vehicle owners don’t pay gas tax.

3)  HB 3991A also increases the payroll tax from .1% to .2% through 2027. This will effectively double the current payroll tax from $1 per $1,000 of income to $2 per $1,0000 income. For someone making $50,000 per year, their payroll tax will increase from $50 per year to $100 per year. All transit programs across Oregon will be eligible to receive funding from this revenue.

4)  The bill provides a pathway for resolving the state’s Highway Cost Allocation Study, which determines the rate setting for weight-miles that heavy vehicles pay in addition to modernizing the rate structure for diesel.

5)  Finally, HB 3991A increases accountability measures for the Oregon Department of Transportation (ODOT), including: the appointment of the agency’s director, which is now done by the governor; several reporting requirements from ODOT; and adding legislative oversight of decision-making.
