Pilot Car & Escort Requirements

Oregon publishes a dedicated pilot car guide broken out by highway district, since escort requirements vary by district depending on a load's width, height, overall length, and overhang for each specific highway.

Axle Regulations

Max weight per inch of tire width
600 lb.
Single axle
20,000 lb.
Tandem
34,000 lb.
Gross weight

Max permit — single axle

Up to 48,000 lbs per tandem axle is allowed if the combination has at least 9 axles with a steer axle followed by four consecutive 8-foot-wide (standard) tandem axles; up to 52,800 lbs is allowed with 10-foot-wide axles and 4 tires per axle; up to 60,000 lbs with 10-foot-wide axles and 8 tires per axle (the same tiers apply to single-trip permits). Common annual permit uses include Extended Weight (up to 105,500 lbs for a divisible load) and Overwidth (for a single, non-divisible load).

Trip & Fuel Permits

A valid trip permit from another state is honored in Oregon, provided proof of insurance is kept in the vehicle. A Heavy Motor Vehicle Trip Permit ($43 for 10 consecutive days) must be obtained prior to operation. A Heavy Trailer Trip Permit ($10 for 10 consecutive days) allows use of an unregistered trailer with a loaded weight over 8,000 lbs, or a fixed-load or special-use trailer. A Temporary Pass is issued when the weight-mile tax is validated upfront and combined GVW exceeds 26,000 lbs, limited to 5 or more per account for one unit or 35 in a rolling 12-month period.

Running Hours & Holiday Restrictions

Travel is generally permitted 1/2 hour before sunrise to 1/2 hour after sunset, 7 days a week, from Labor Day to Memorial Day. From Memorial Day to Labor Day, Saturday travel is allowed only until noon and none on Sunday, except loads not exceeding 14' wide may travel weekend daytime hours on the Interstate west of the Cascade summit and on any authorized highway east of it. Loads up to 10' wide on "green" routes and up to 12' wide on Interstates are allowed to travel at night. Local restrictions apply in Portland, Eugene, Grants Pass, and other areas.

Flags, Lights & Banners

End-load lights are required when visibility is under 500 feet due to darkness or reduced visibility, with the outermost extremities of a wide load illuminated at night (amber forward/intermediate side markers, red rearward markers). Widths over 10' on a two-lane highway (or 12' on a multi-lane highway) require amber warning lights on the cab, unless traveling with a minimum of two pilot cars. "Oversize Load" signs are required on the front of the tractor and rear of the load or trailer for wide loads and vehicles/loads over 80' long — 7' wide, 18" high, black 10-inch letters on a yellow background. Red or fluorescent orange flags at least 18" square are required at the outermost extremity during daylight hours.

Tire Regulations

Check tire inflation pressure with a gauge (PSI). Minimum tread depth is 2/32 inch. Tire chains are required when conditions demand it — snow, ice, or other inclement weather with SNOW ZONE signs posted.

Cost varies depending on whether the permit covers Interstate travel only or also includes city and county roads; some permits are commodity specific.

Road Conditions

Road construction is one of the most dangerous occupations in the US, and work zone crashes are serious for both workers and drivers. Pay attention to the driving task, slow down for orange signs, barrels, cones, and barricades, obey speed zones, don't tailgate, merge into the correct lane well in advance, and stay alert for narrow or closed lanes, closed shoulders, and workers near live traffic. Move over for highway workers when possible, and expect delays — plan your trip via TripCheck.com and be patient.

Manufactured Homes / Mobile Homes

Specific information for moving oversized mobile and manufactured homes — fees, road restrictions, pilot/escort car requirements, and travel times — varies by dimension and is published through Oregon's dedicated manufactured-home moving resource.
