Auburn, WA
Farm Equipment Transport

Farm equipment generally moves without an oversize permit in Washington when the loaded vehicle remains within 8 feet 6 inches wide, 14 feet high, 53 feet in trailer length, and 80,000 pounds gross vehicle weight. Axle spacing, bridge ratings, and city restrictions must also be reviewed before transport through Auburn.

Oversized agricultural machinery moving through Auburn requires a Washington permit when the loaded vehicle exceeds legal dimensions or weight limits. Permit routing is based on the equipment measurements, axle configuration, gross weight, and roadway restrictions. Separate city or county approval may be required when Auburn streets or King County roads are included.

Oversized agricultural equipment moving through Auburn may require certified pilot or escort vehicles based on Washington rules and permit conditions. The number and position of escorts depend on the load dimensions, roadway type, visibility, and route restrictions. Height-pole vehicles or additional escorts may be required for especially tall or wide loads.

Oversized agricultural equipment moving through Auburn must comply with the travel periods authorized by the Washington permit. Night movement may require additional approval, escorts, lighting, or route review. Seattle-Tacoma traffic, holidays, weather, visibility, and local restrictions can also affect dispatch timing.

Farm equipment transported through Auburn requires a trailer and securement plan matched to the machinery’s dimensions, weight, and condition. Chains, binders, straps, blocking, lights, and brakes should be inspected before entering regional traffic. Washington permit conditions may also require flags, signs, pilot cars, or height-clearance equipment.

Transport routes around Auburn should account for Seattle-Tacoma traffic, steep grades, bridge limits, seasonal weather, and access between WA-18, WA-167, and rural properties. Farm and nursery entrances should be reviewed for road width, surface stability, overhead clearance, and trailer staging space.
