Oregon Oversize & Overweight Permits

When Oregon needs a permit

Over 8'6" wide, 14' high, or 80,000 lb, you need an ODOT over-dimension permit (ORS 818.225; OAR 734-082). Single-trip oversize starts near $8; overweight adds a per-mile Road Use Assessment Fee. Oregon runs civilian pilot cars with certified flaggers, not state police. Move in daylight only. Summer overwidth runs Monday-Thursday to 11 a.m. and 6 p.m. to dusk, Friday mornings only, and six holidays are full blackouts.

Thresholds, escorts, and curfews

• Legal max before a permit: Permit needed over 8'6" wide, 14' high, or 80,000 lb; also for over-length combinations beyond the legal length.
• Escort / pilot car: Oregon uses civilian pilot cars with certified flaggers, not state police. One car covers width (front, or rear on multilane highways); front and rear when two are required. Thresholds are set on the permit, and loads over 14'6" high trigger an overheight pole car.
• Superload: Superload over 16' wide (14' on a two-lane state highway), 17' high, or 150' long. It moves under engineering review and a route survey through the ODOT Commerce and Compliance Division, not a same-week single-trip permit.
• Travel curfew: Overwidth travel hours come off ODOT's Special Transportation Permit Attachment H (Form 2362, revised 01-2026). Over 12' wide is daylight only, a half hour before sunrise to a half hour after sunset; 8'7" to 10' may run nights on all Interstates and the green routes on Route Map 2, and 10'1" to 12' on the Interstates only. Summer weekends, the last Monday in May to the first Monday in September, close the non-Interstates west of the Cascades after noon Saturday and all day Sunday, and close every route over 14' wide. Portland, Salem, Eugene, Grants Pass, and Medford hold 12'1" to 14' on the non-Interstates and on I-5 north of OR217 and at Exits 24-33 from 7-9 a.m. and 4-6 p.m. on business days, and hold anything over 14' wide from 11 a.m. to 1 p.m. Six holidays restrict travel (New Year's, Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas): over 14' wide you park from noon the day before until a half hour before sunrise the day after, while 8'7" to 14' can still run authorized routes on the weekend in between. Long logs, poles, and piling over 105' shut down from noon the Wednesday before Thanksgiving to sunrise the Monday after.
• Permit fee: Single-trip oversize starts near $8. Overweight is a small variance fee plus a per-mile Road Use Assessment Fee (RUAF) drawn from ODOT's published GVW x axle-count rate table times Oregon route miles. Continuous/annual permits are available for repeat runs.
