Kennewick, 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 limits, and local restrictions must also be reviewed, and over-legal machinery may require a Washington permit.

Farm equipment exceeding Washington’s legal dimensions or weight limits requires an oversize or overweight permit before moving through Kennewick. Permit planning is based on the complete loaded dimensions, axle configuration, gross weight, and proposed route. City or county approval may also be required when the permitted route includes Kennewick streets or Benton County roads.

Farm equipment transported through Kennewick may require certified pilot or escort vehicles when the loaded dimensions exceed Washington thresholds or the permit specifies additional traffic control. Escort placement depends on the load dimensions and roadway type, with front, rear, or multiple escorts possible. Height-pole vehicles or additional coordination may be required for taller or unusually large machinery.

Oversized agricultural equipment moving through Kennewick must follow the travel hours listed on the Washington permit. Night movement may require additional approval, lighting, escorts, or route review, particularly for wider, taller, or longer loads. Holiday restrictions, weather, visibility, and traffic conditions may also delay movement on I-82, US-395, or local roads.

Agricultural machinery transported through Kennewick must be secured with equipment rated for the load, including properly positioned chains, binders, straps, and blocking. Tires, attachments, booms, and movable components should be checked before dispatch. Washington permit conditions may also require warning devices, lighting, flags, escorts, or other safety equipment.

Route planning around Kennewick should account for Columbia River crossings, irrigated farm roads, seasonal agricultural traffic, and access between I-82, US-395, and rural delivery points. Vineyard, orchard, and farm entrances should be reviewed for road width, surface stability, overhead clearance, and trailer turnaround space.
