(1)
Can a vehicle, or vehicle
			 combination, acquire a permit to exceed the dimensions for legal vehicles in
			 regular operation when moving items of a divisible nature?
Yes. There
			 are specific configurations that receive extra length, extra width, or extra
			 height when carrying a divisible load.
(2)
What configurations can be issued a
			 permit, and how are they measured?
The configurations and measurement
			 criteria are:
(a) An overlength permit may be
			 issued to a truck-tractor to pull a single trailer or semi-trailer, with a
			 trailer length not to exceed fifty-six feet. The measurement for the single
			 trailing unit will be from the front of the trailer (including draw bar when
			 used), or load, to the rear of the trailer, or load, whichever provides the
			 greater distance up to fifty-six feet. Rear overhang may not exceed fifteen
			 feet.
(b) An overlength permit may
			 be issued to a truck-tractor to pull a set of double trailers, composed of a
			 semi-trailer and full trailer or second semi-trailer, with a combined trailer
			 length not to exceed sixty-eight feet. The measurement for double trailers will
			 be from the front of the first trailer, or load, to the end of the second
			 trailer or load, whichever provides the greatest distance up to sixty-eight
			 feet. Note: If the truck-tractor is carrying an allowable small freight
			 compartment (dromedary box), the total combined length of the combination,
			 combined trailer length notwithstanding, is limited to seventy-five
			 feet.
(c) An overlength permit may
			 be issued to a log truck pulling a pole-trailer, trailer combination, carrying
			 two distinct and separate loads, as if it was a truck-tractor pulling a set of
			 double trailers. Measurement for the log truck, pole-trailer, trailer
			 combination will be from the front of the first bunk on the truck to the rear
			 of the second trailer, or load, whichever provides the greatest distance up to
			 sixty-eight feet.
(d) An overheight
			 permit may be issued to a vehicle or vehicle combination, hauling empty apple
			 bins, not to exceed fifteen feet high. Measurement is taken from a level
			 roadbed. This permit may be used in conjunction with either of the overlength
			 permits in (a) or (b) of this subsection. The permit may also provide an
			 exemption from a front pilot/escort vehicle as required by WAC
			 468-38-100(1)(h).
			 The exemption does not limit the liability assumed by the permit
			 applicant.
(e) An overheight permit
			 may be issued to a vehicle or vehicle combination owned by a rancher and used
			 to haul the rancher's own hay from the rancher's own fields to feed the
			 rancher's own livestock, not to exceed fifteen feet high, measured from a level
			 roadbed. This permit may be used in conjunction with either of the overlength
			 permits in (a) or (b) of this subsection. The permit may also provide an
			 exemption from a front pilot/escort vehicle as required by WAC
			 468-38-100(1)(h).
			 The exemption does not limit the liability assumed by the permit
			 applicant.
(f) An overwidth permit,
			 termed a tarping system permit, may be issued to a vehicle or vehicle
			 combination for a divisible load when such vehicle is equipped with a tarping
			 system as defined in WAC
			 468-38-073(5)(n)
			 and under the following conditions:
(i) The
			 divisible load must be authorized by a tarping system permit in order to
			 display the special conditions on the permit;
(ii) A tarping system permit is required for
			 any divisible load exceeding one hundred and two inches (eight feet six inches)
			 in width but not exceeding nine feet in width, all of which must be within the
			 confines of the tarping system dimensions. For example, bulging of the tarping
			 material, to accommodate the load, is not authorized;
(iii) A tarping system permit is authorized
			 to be used in conjunction with either of the overlength permits authorized
			 under (a) or (b) of this subsection; and
(iv) Vehicles operating with a tarping system
			 permit are exempt from the requirements and restrictions listed in WAC
			 468-38-075(1).
