Washington State issues single-trip permits for indivisible loads that exceed the legal size and weight restrictions. These permits allows the one-way carriage of a load from a starting point to a destination during the time range specified in the permit. If the load must be returned to its original site, a second permit is often necessary. The charge for an oversize permit is normally fixed at $10, but the cost of an overweight permit varies according to the weight of the load.
This permit grants unlimited mobility for up to 365 days, allowing a specific vehicle and allowed load to travel one-way between two places on defined routes.
To get an annual permit, a load must fulfill the following criteria:
maximum width – 14′; 15′ prefabricated dwelling (trailer length cannot exceed 75′)
The maximum height is 15 feet and the maximum length is 125 feet (for vehicle combinations), with a single trailer measuring 56 feet and a double trailer measuring 68 feet.
Note: The weight per axle should not exceed 20,000 pounds.
The fee varies according on the permit, which starts at $100 ($10 each month).

Vehicles transporting oversize loads must show banners or placards that read "Oversize Load."
The signs must be at least 7 feet in length and 18 inches in height, with black lettering 10 inches tall on a yellow background.
To improve visibility during night transit, oversize loads must include amber lights on the front and sides, as well as red lights on the rear corners.

On two-lane roadways, loads more than 11 feet require one front and one rear pilot car.
On multi-lane roadways, loads larger than 14 feet require one rear pilot vehicle.
Loads larger than 20 feet require one front and one rear pilot vehicle on multi-lane roadways.
