WAC 468-38-290
Farm implements. (1) For purposes of
issuing special farm implement permits and certain permit
exemptions, what is considered a farm implement? A farm
implement includes any device that directly affects the
production of agricultural products, including fertilizer and
chemical applicator apparatus (complete with auxiliary
equipment). For purposes of this section, the implement must
be nondivisible, weigh less than sixty-five thousand pounds,
and comply with the requirements of RCW 46.44.091. The
implement must be less than twenty feet in width and not
exceed sixteen feet in height. However, for purposes of this
section, farm implements must not exceed fourteen feet in
height in the counties of Whatcom, Skagit, Island, Snohomish,
and King. If the implement is self-propelled, it must not
exceed forty feet in length, or seventy feet overall length if
being towed. The implement must move on pneumatic tires, or
solid rubber tracks that will not damage public highways with
parts that extend beyond the tracks. Implements exceeding any
of these criteria must meet all requirements for special
permits as referenced in other sections in this chapter and
chapter 46.44 RCW.
(2) What dimensional criteria requires a special permit
to move extra-legal farm implements? Self-propelled farm
implements, including a farm tractor pulling no more than two
implements, that exceed fourteen feet in height or sixteen
feet in width, but less than twenty feet in width, are
required to get a special permit for movement of farm
implements on state highways. Note: A tow vehicle capable of
carrying a load (i.e., a truck of any kind) may not tow more
than one trailing implement.
(3) Will the opportunity to purchase a special permit to
move oversize farm implements be affected if the implement(s)
is carried on another vehicle? The opportunity to purchase a
special permit for farm implements as defined in subsection
(1) of this section will not be affected unless one of the
following circumstances occurs:
(a) The authorized users of the permit outlined in
subsection (5) of this section use a commercial for-hire
service to move the implement(s); or
(b) The loaded farm implement creates a combined height
that exceeds sixteen feet; or
(c) The loaded farm implement causes the hauling vehicle
to exceed legal weight limits. The farm implement weight may
exceed sixty-five thousand pounds when carried on another
vehicle; however, the combined gross weight of the hauling
unit carrying the implement may not exceed the legal weight
limits established in RCW 46.44.041 Maximum gross
weights -- Wheelbase and axle factors.
If any of these circumstances occur, the provisions of
this subsection will not apply to the movement of the farm
implement. The movement will be required to comply with the
requirements for special permits as provided in chapter 46.44 RCW and in other sections in this chapter.
(4) How does the special permit farm implement
application process differ from the special permit process
outlined in WAC 468-38-050? Due to the size of the implement
and the potential for use in multiple jurisdictions, the
written application must be submitted to the department's
Olympia office for approval. Permits can be requested for
three-month periods up to one year. Once approved, a special
permit may be generated from the Olympia office by facsimile
or a letter of authorization will be sent authorizing the
applicant to acquire a special permit at the nearest permit
sales location. If the movement of the farm implement(s) is
confined to a single department maintenance area, the
applicant may make direct written application to that
maintenance area office in lieu of the Olympia office.
(5) Who is authorized to purchase a farm implement
special permit? The purchase and use of a special permit to
move farm implements is restricted to a farmer, or anyone
engaged in the business of selling, repairing and/or
maintaining farm implements.
(6) Will the special permit restrict the movement to a
specific area? The special permit to move farm implements is
generally restricted to six contiguous counties or less. With
proper justification, the area can be expanded. Farm
implements may only travel on highway structures that are
designed to support the weight of the farm implement.
(7) Is department notification required before moving
implement(s)? Affected department maintenance areas must be
notified at least eight (8) hours in advance of implement(s)
movements in excess of sixteen feet wide. Movements of
implements that exceed the legal weight limit established in
RCW 46.44.041 must contact all affected department maintenance
areas at least eight hours in advance for weight restriction
information. The notification is for the purpose of ensuring
that there will not be any planned activity or weight
restrictions that would restrict the move. Locations of
department maintenance area offices and phone listings are
provided with each letter authorizing the purchase of the farm
implement special permit.
(8) What safety precautions must be taken when moving
extra-legal farm implement(s)? The movement of extra-legal
farm implements must comply with the safety requirements
following:
(a) Oversize load signs: If the farm implement exceeds
ten feet in width or exceeds fourteen feet in height from the
road surface, it must display an "OVERSIZE LOAD" sign(s) visible
to both oncoming traffic and overtaking traffic. Signs must
comply with the requirements of WAC 468-38-155(7). If the
implement is both preceded and followed by pilot/escort
vehicles, a sign is not required on the implement itself.
(b) Curfew/commuter hours: Movement of a farm implement
in excess of ten feet wide or fourteen feet in height must
comply with any published curfew or commuter hour
restrictions, which are an attachment to the farm implement
special permit.
(c) Red flags: If the farm implement is moving during
daylight hours, and exceeds ten feet in width, the vehicle
configuration must display clean, bright red flags. The red
flags must measure at least eighteen inches square and be able
to wave freely. The red flags are to be positioned at all
four corners, or extremities, of the overwidth implement and
at the extreme ends of all protrusions, projections or
overhangs. If a transported implement overhangs the rear of a
transporting vehicle or vehicle combination by more than four
feet, one red flag is required at the extreme rear. If the
width of the rear overhang or protrusion exceeds two feet, two
red flags must be positioned at the rear to show the maximum
width of the overhang or protrusion.
(d) Warning lights and slow moving emblem: Lamps and
other lighting must be in compliance with RCW 46.37.160. In
addition to lighting requirements, RCW 46.37.160 requires the
use of a "slow moving emblem" for moves traveling at
twenty-five miles per hour or less.
(e) Convoys: Convoys, the simultaneous movement of two
or more individually transported implements, are authorized
when the criteria are met following:
(i) A minimum of five hundred feet is maintained between
vehicles to allow the traveling public to safely pass;
(ii) If five or more vehicles are lined up behind any one
of the convoy implements, the operator must pull off the road
at the nearest point wide enough to accommodate the
implement(s) and to allow the vehicles to safely pass; and
(iii) The convoy is preceded and followed with properly
equipped pilot/escort vehicles.
(9) Are there any unique requirements or exemptions
regarding the use of farm implement(s) pilot/escort vehicles?
Pilot/escort vehicles must comply with the requirements of WAC 468-38-100, except for the specific exemptions related only to
special permits for moving farm implement(s) following:
(a) A farmer, farm implement dealer, or agri-chemical
dealer (including employees of each) is exempt from WAC 468-38-100(4) regarding operator certification, WAC 468-38-100
(8)(a) and (b) regarding pilot/escort vehicle physical
description, WAC 468-38-100 (10)(f) regarding use of height
measuring device when the implement does not exceed fifteen
feet in height measured from the road surface, and WAC 468-38-100(11) regarding passengers, when moving a farm
implement off the interstate and to the interstate segments
following:
(i) I-90 between Exit 109 (Ellensburg) and Exit 270 (Four
Lakes);
(ii) I-82 between Junction with I-90 (Ellensburg) and
Exit 31 (Yakima);
(iii) I-82 between Exit 37 (Union Gap) and
Washington/Oregon border;
(iv) I-182 between Junction with I-82 (West Richland) and
Junction with SR-395; or
(v) I-5 between Exit 208 (Arlington) and Exit 250 (south
of Bellingham).
(b) On two lane highways, one pilot/escort vehicle must
precede and one must follow the implement(s) when the width
exceeds twelve feet six inches. Implements up to twelve feet
six inches wide are exempt from using pilot/escort vehicles.
(c) On all highways, one pilot/escort vehicle equipped
with a height measuring device in compliance with WAC 468-38-100 (10)(f) and (14) must precede the farm implement
when the height of the farm implement exceeds fifteen feet
measured from the road surface. Movements within a sixty mile
radius from the place where the implement(s) is principally
used or garaged are exempt from this requirement.
(d) A flag person(s) may be used in lieu of a
pilot/escort vehicle for moves under five hundred yards. This
allowance must be stated on any farm implement special permit
that may be required for the move.
(e) Posting a route may also be used in lieu of a
pilot/escort vehicle(s) when the route is less than two miles.
Signs must state, "OVERSIZE VEHICLE MOVING AHEAD" on a background
square at least three feet on each side (in diamond
configuration), with black lettering on orange background. The signs must be placed at points before the oversize
implement enters or leaves the highway, and at access points
along the way. Signs must be immediately removed after the
move has been completed.
