(Salem, OR) -- The Oregon Department of Transportation says gas tax revenue peaked in 2025. Gas consumption in Oregon hit its peak in 2018. More fuel efficient, and electric, vehicles will cause gas consumption to trend down in the future. The legislature approved two cent gas tax increases in 2020, 2022, and 2024 which helped increase revenue. ODOT says there are no future increases and declining gas tax revenue means rougher roads, more delays, more closures and less reliable travel across the state. The 2027 Legislature is expected to discuss transportation funding.
