AMENDATORY SECTION(Amending WSR 05-04-053, filed 1/28/05, effective 2/28/05)
WAC 468-38-070 Maximums and other criteria for special permits -- Nondivisible. (1) Are there maximum dimensions established for moving nondivisible over-dimensional vehicles and/or loads? Yes. In all instances the general safety of the public is considered paramount and will ultimately govern over-dimensional moves. There are some general rules; however, physical barriers determine most maximums for over-dimensional moves. Over-dimensional maximums are addressed as follows:
(a) Overwidth: As stipulated in RCW 46.44.092, fourteen feet on any two-lane highway; twenty feet on any multiple-lane highway where a physical barrier serving as a median divider (i.e., jersey barrier, cyclone fence, guardrail, etc.) separates the oncoming and opposing traffic lanes; thirty-two feet on any multiple-lane undivided highway. Permits may be issued for widths in excess of the preceding limits when traveling on highway segments that by design can accommodate the greater width.
(b) Overheight: Any move involving height, especially permitted moves exceeding fourteen feet, are governed by the ability to clear overhead obstructions such as bridges, underpasses, wires, overhead signs, and other objects. The issuance of a permit does not insure the route to be free of overhead obstructions. It is the responsibility of the permit applicant to check, or prerun, the proposed route and provide for safe maneuvers around the obstruction or detours as necessary. Structures owned by the state should be reviewed with department field personnel to determine safe navigation of the move, including options for temporary removal of obstructions. Detours off the state route onto county or city roads require authorization from those jurisdictions. A traffic control plan (see WAC 468-38-405 (3)(d)) may be requested for approval by the department before a permit is issued.
(c) Overlength: Routes will be limited to over-dimensional moves based on ability to negotiate curves, interchanges, entrance and exit roadways and other obstacles.
(2) Are there maximum weights established for moving nondivisible overweight vehicles and/or loads? Yes. Weight maximums for the movement of a nondivisible load under special permit are established in RCW 46.44.091. In addition, tire loading for the movement of a nondivisible load is limited to the lesser of six hundred pounds per inch width of tire or the tire manufacturer's rating with proper inflation, as determined by the nomenclature imprinted on the tire.
(3) Are there maximums and/or other criteria established for the use of specific vehicle combinations when moving over-dimensional nondivisible loads? Yes. The maximums for specific vehicle combinations are as follows:
(a) Truck-tractor pulling a semi-trailer or full trailer: Trailers in excess of legal length and/or width dimensions, or the permitted length of fifty-six feet, shall not exceed the length or width of the nondivisible load being transported. The department may grant an exception when the added dimension is necessary to spread the weight of the load to comply with requirements established by the department to protect the infrastructure. Jeeps and/or boosters may be added to the trailer to help distribute weight as necessary. A "pusher" power unit may also be added to the configuration upon approval of the department. Jeeps, boosters and pusher power units will be considered part of the trailing unit plus load measurement.
(b) Truck-tractor pulling semi-trailer and full trailer (or two semi-trailers in B-train configuration): The combined trailer length, including the space between trailers, may not exceed sixty-one feet. This combination is limited to nondivisible loads not to exceed ten feet wide. Both trailers may carry a nondivisible load, with the widest load carried on the first trailer. Trailers in excess of legal width shall not exceed the width of the nondivisible load being transported. This combination may not carry overheight, overlength or overweight loads.
(c) Truck and trailer: There are ((
two)) three scenarios
for this combination:
(i) Both truck and trailer carrying loads: The combined overall length of the combination when carrying a nondivisible overlength load must not exceed eighty-five feet. Any nondivisible overlength load is restricted to only one vehicle. The trailer may be loaded with the overhang entirely to the rear of the trailer, or the truck may be loaded with the overhang entirely to the front of the truck. Both truck and trailer may carry overwidth and overheight loads. The truck and/or trailer in this configuration may not carry an overweight nondivisible load.
(ii) Unladen truck and trailer: The unladen truck may be treated as a truck-tractor and the combination addressed as described in (a) of this subsection: Provided, That the truck-tractor is not carrying any load of any kind, and that its use as an unladen truck is specified on the special permit. The trailing unit is measured from the foremost point of the draw bar or load, whichever is greater, to the rearmost part of the trailer or load, whichever is greater. This combination may carry a nondivisible overweight load on the trailer. For example, an unladen dump truck may acquire a special permit to pull a tilt trailer with a dozer or backhoe where the trailer load causes the axles to exceed legal weight. An unladen truck with unladen trailer must not exceed an overall length of eighty-five feet.
(iii) Log truck with pole trailer - nondivisible poles: A log truck with pole trailer hauling a single load of nondivisible poles, where the log truck is supporting a proportionate share of the load, must be permitted for overlength based on load length, similar to a truck tractor semi-trailer configuration. Measurement will be taken from the front of load or bunks, whichever comes first, to the end of the load. No portion of the pole trailer may extend beyond the load in an overlength configuration.
(4) Can a vehicle, or vehicle combination, carry multiple pieces when using an over-dimensional nondivisible special permit? Yes, under the following conditions:
(a) The vehicle(s) and load are transported at legal weights.
(b) The largest nondivisible piece(s) must be loaded to its practicable minimum. No single piece may create a dimension greater than the dimension it would create if loaded properly and carried by itself.
(c) Additional pieces may be added within the envelope dimension created by the largest piece(s) loaded to its practicable minimum. The envelope should be viewed as an imaginary cube with height, length and width defined by the extremities, regardless of shape, of the over-dimensional piece(s) and other legal dimensions as necessary. The department will provide an illustrative example upon request.
(5) Are there any circumstances when an over-dimensional vehicle(s) can move a legal size load? Yes, when the following conditions have been met:
(a) The vehicle(s) are making the move in conjunction with being in route to pick up a nondivisible load under special permit (front haul); or
(b) The vehicle(s) are making the move in conjunction with returning from a delivery of a nondivisible load under special permit (back haul); and
(c) The route traveled is the same route that would have been used if a legal load had not been moved; and
(d) The front haul or back haul is noted on the special permit used for the nondivisible move.

A vehicle or vehicle combination operating on a special permit for overweight only, in compliance with all legal dimension limits, is exempt from all of the requirements/restrictions included in subsection (1)(a) through (d) of this section: Provided, That the vehicle or vehicle combination can maintain posted speed limits. This exemption may be used in conjunction with the height and width exemption in subsection (3) of this section.
[Statutory Authority: RCW 46.44.090. 05-04-053, § 468-38-075, filed 1/28/05, effective 2/28/05; 02-06-106, § 468-38-075, filed 3/5/02, effective 4/5/02; 94-07-055 (Order 143), § 468-38-075, filed 3/11/94, effective 3/11/94; 93-21-008 (Order 139), § 468-38-075, filed 10/8/93, effective 11/8/93.]
(a) The vehicle(s) or load is over eleven feet wide. Two pilot/escort vehicles are required on two lane roads, one in front and one in back.
(b) The vehicle(s) or load is over fourteen feet wide. One escort vehicle is required at the rear of the movement on multilane highways.
(c) The vehicle(s) or load is over twenty feet wide. Two pilot/escort vehicles are required on multilane undivided highways, one in front and one in back.
(d) The trailer length, including load, of a tractor/trailer combination exceeds one hundred five feet, or when the rear overhang of a load measured from the center of the rear axle exceeds one-third of the trailer length plus load of a tractor/trailer or truck/trailer combination. One pilot/escort vehicle is required at the rear of the movement on two-lane highways.
(e) The trailer length, including load, of a tractor/trailer combination exceeds one hundred twenty-five feet. One pilot/escort vehicle is required at the rear of the movement on multilane highways.
(f) The front overhang of a load measured from the center of the front steer axle exceeds twenty feet. One pilot/escort vehicle is required at the front on all two-lane highways.
(g) The rear overhang of a load on a single unit vehicle,
measured from the center of the rear axle, exceeds ((
the total length of a single unit vehicle with load)) twenty
feet. One pilot/escort vehicle is required at the rear of the
movement on two-lane highways.
(h) The height of the vehicle(s) or load exceeds fourteen feet six inches. One pilot/escort vehicle with height measuring device (pole) is required at the front of the movement on all state highways and roads.
(i) The operator, using rearview mirrors, cannot see two hundred feet to the rear of the vehicle or vehicle combination.
(j) In the opinion of the department, a pilot/escort vehicle(s) is necessary to protect the traveling public. Assignments of this nature must be authorized through the department's administrator for commercial vehicle services.
(2) Can a pilot/escort vehicle be temporarily reassigned a position relative to the load during a move? When road conditions dictate that the use of the pilot/escort vehicle in another position would be more effective, the pilot/escort vehicle may be temporarily reassigned. For example: A pilot/escort vehicle is assigned to the rear of an overlength load on a two-lane highway. The load is about to enter a highway segment that has curves significant enough to cause the vehicle and/or load to encroach on the oncoming lane of traffic. The pilot/escort vehicle may be temporarily reassigned to the front to warn oncoming traffic.
(3) Can a certified flag person ever substitute for a pilot/escort vehicle? In subsection (1)(d) and (e) of this section, the special permit may authorize a riding flag person, in lieu of a pilot/escort vehicle, to provide adequate traffic control for the configuration.
(4) Must an operator of a pilot/escort vehicle be certified to operate in the state of Washington? Yes. To help assure compliance with the rules of this chapter, consistent basic operating procedures are needed for pilot/escort vehicle operators to properly interact with the escorted vehicle and the surrounding traffic. Operators of pilot/escort vehicles, therefore, must be certified as having received department-approved base level training as a pilot/escort vehicle operator. A pilot/escort vehicle operator with a Washington state driver's license must have a valid Washington state pilot/escort vehicle operator certificate/card which must be on the operator's person while performing escort vehicle operator duties. Escort vehicle operators with a driver's license from a jurisdiction other than Washington state may acquire a Washington state escort vehicle operator certificate/card, or operate with a certification from another jurisdiction approved by the department, subject to the periodic review of the issuing jurisdiction's certification program. A current list of approved programs will be maintained by the department's commercial vehicle services office. Washington state pilot/escort vehicle operator cards must be renewed every three years.
(5) What are the pretrip procedures that must be followed by the operator of a pilot/escort vehicle?
(a) Discuss with the operator of the extra-legal vehicle the aspects of the move including, but not limited to, the vehicle configuration, the route, and the responsibilities that will be assigned or shared.
(b) Prerun the route, if necessary, to verify acceptable clearances.
(c) Review the special permit conditions with the operator of the extra-legal vehicle.
(d) Determine proper position of required pilot/escort vehicles and set procedures to be used among the operators.
(e) Assure availability of additional certified flag persons if stated as a condition of the oversize/overweight special permit.
(f) Check mandatory equipment, provided in subsections (9) and (10) of this section. Each operator is responsible for his or her own vehicle.
(g) Check two-way communication system to ensure clear communications and predetermine the channel to be used.
(h) Adjust mirrors, mount signs and turn on lights, provided in subsections (8)(e) and (9)(a) and (b) of this section.
(6) What are the responsibilities of the operator of a pilot/escort vehicle when assigned to be in front of the extra-legal movement? The operator shall:
(a) Provide general warning to oncoming traffic of the presence of the permitted vehicle by use of signs and lights, provided in subsection (9) of this section;
(b) Notify the operator of the extra-legal vehicle, and the operator(s) of any trailing pilot/escort vehicle(s), about any condition that could affect either the safe movement of the extra-legal vehicle or the safety of the traveling public, in sufficient time for the operator of the extra-legal vehicle to take corrective action. Conditions requiring communication include, but are not limited to, road-surface hazards; overhead clearances; obstructions; traffic congestion; pedestrians; etc.;
(c) Provide guidance to the extra-legal vehicle through lane changes, egress from one designated route and access to the next designated route on the approved route itinerary, and around any obstacle;
(d) In the event of traffic buildup behind the extra-legal vehicle, locate a safe place adjacent to the highway where the extra-legal vehicle can make a temporary stop. Notify the operator of the extra-legal vehicle, and the operator(s) of any trailing pilot/escort vehicle(s), in sufficient time for the extra-legal vehicle to move out of the traffic flow into the safe place, allowing the following traffic to pass safely;
(e) In accordance with training, be far enough in front of the extra-legal vehicle to signal oncoming traffic to stop in a safe and timely manner before entering any narrow structure or otherwise restricted highway where an extra-legal vehicle has entered and must clear before oncoming traffic can enter;
(f) In accordance with training, do not be any farther ahead of the extra-legal vehicle than is reasonably prudent, considering speed of the extra-legal vehicle, other traffic, and highway conditions. Do not exceed one-half mile distance between pilot/escort vehicle and extra-legal vehicle in order to maintain radio communication, except when necessary to safely travel a long narrow section of highway; and
(g) Assist in guidance to a safe place, and/or traffic control, in instances when the extra-legal vehicle becomes disabled.
(7) What are the responsibilities of the operator of a pilot/escort vehicle when assigned to be at the rear of the extra-legal movement? The operator shall:
(a) Provide general warning to traffic approaching from the rear of the extra-legal vehicle ahead by use of signs and lights, provided in subsection (9) of this section;
(b) Notify the operator of the extra-legal vehicle, and the operator(s) of any leading pilot/escort vehicle(s), about any condition that could affect either the safe movement of the extra-legal vehicle or the safety of the traveling public, in sufficient time for the operator of the extra-legal vehicle to take corrective action. Conditions requiring communication include, but are not limited to, objects coming loose from the extra-legal vehicle; flat tires on the extra-legal vehicle; rapidly approaching traffic or vehicles attempting to pass the extra-legal vehicle; etc.;
(c) Notify the operator of the extra-legal vehicle, and/or the operator of the lead pilot/escort vehicle, about traffic buildup or other delays to normal traffic flow resulting from the extra-legal move;
(d) In the event of traffic buildup behind the extra-legal vehicle, notify the operator of the extra-legal vehicle, and the operator(s) of any pilot/escort vehicle(s) in the lead, and assist the extra-legal vehicle in its move out of the traffic flow into the safe place, allowing the following traffic to pass safely;
(e) In accordance with training, be far enough behind the extra-legal vehicle to provide visual warning to approaching traffic to slow or stop in a timely manner, depending upon the action to be taken by the extra-legal vehicle, or the condition of the highway segment (i.e., limited sight distance, mountainous terrain, narrow corridor, etc.);
(f) Do not follow more closely than is reasonably prudent, considering the speed of the extra-legal vehicle, other traffic, and highway conditions. Do not exceed one-half mile distance between the pilot/escort vehicle and the extra-legal vehicle in order to maintain radio communication, except when necessary to safely travel a long narrow section of highway; and
(g) Assist in guidance to a safe place, and/or traffic control, in instances when the extra-legal vehicle becomes disabled.
(8) What kind of vehicle can be used as a pilot/escort vehicle? In addition to being in safe and reliable operating condition, the vehicle shall:

(9) In addition to equipment required by traffic law, what additional equipment is required on the vehicle when operating as a pilot/escort, and when is it used?
(a) A minimum of two flashing or rotating amber (yellow) lights, positioned above the roof line, visible from a minimum of five hundred feet to approaching traffic from the front or rear of the vehicle. Light bars, with appropriately colored lights, meeting the visibility minimums are acceptable. Lights must only be activated while escorting an extra-legal vehicle, or when used as traffic warning devices while stopped at the side of the road taking height measurements during the prerunning of a planned route. The vehicle's headlights must also be activated while escorting an extra-legal vehicle.
(b) A sign reading "OVERSIZE LOAD," measuring at least five feet wide, ten inches high with black lettering at least eight inches high in a one-inch brush stroke on yellow background. The sign shall be mounted over the roof of the vehicle and shall be displayed only while performing as the pilot/escort of an extra-legal load. When the vehicle is not performing as a pilot/escort, the sign must be removed, retracted or otherwise covered.
(c) A two-way radio communications system capable of providing reliable two-way voice communications, at all times, between the operators of the pilot/escort vehicle(s) and the extra-legal vehicle(s).
(10) What additional or specialized equipment must be carried in a pilot/escort vehicle?
(a) A standard eighteen-inch STOP AND SLOW paddle sign.
(b) Three bi-directional emergency reflective triangles.
(c) A minimum of one five-pound B, C fire extinguisher, or equivalent.
(d) A high visibility safety garment designed according to Class 2 specifications in ANSI/ISEA 107-1999, American National Standard for High Visibility Safety Apparel, to be worn when performing pilot/escort duties outside of the vehicle. The acceptable high visibility colors are fluorescent yellow-green, fluorescent orange-red or fluorescent red.
(e) A highly visible colored hard hat, also to be worn when performing pilot/escort duties outside of the vehicle, per WAC 296-155-305.
(f) A height-measuring device (pole), which is nonconductive and nondestructive to overhead clearances, when required by the terms of the special permit. The pole may be carried outside of the vehicle when not in use. See also subsection (14) of this section.
(g) First-aid supplies as prescribed in WAC 296-800-15020.
(h) A flashlight in good working order with red nose cone. Additional batteries should also be on hand.
(11) Can the pilot/escort vehicle carry passengers? A pilot/escort vehicle may not contain passengers, human or animal, except for a certified individual in training status or necessary flag person.
(12) Can the pilot/escort vehicle carry any other items, equipment, or load? Yes, as long as the items, equipment or load have been properly secured: Provided, no equipment or load may be carried in or on the pilot/escort vehicle that:
(a) Exceeds the height, length, or width of the pilot/escort vehicle, or overhangs the vehicle, or otherwise impairs its immediate recognition as a pilot/escort vehicle by the traveling public;
(b) Obstructs the view of the flashing or rotating amber lights, or "OVERSIZE LOAD" sign on the vehicle;
(c) Causes safety risks; or
(d) Otherwise impairs the performance by the operator or the pilot/escort vehicle of the duties required by these rules.
(13) Can a pilot/escort vehicle escort more than one extra-legal load at the same time? No, unless the department determines there are special circumstances that have resulted in an express authorization on the special permit.
(14) When and how must a pilot/escort vehicle use a height-measuring device? The height-measuring device (pole) must be used when escorting an extra-legal load in excess of fourteen feet six inches high, unless an alternative authorization has been granted by the department and stated on the special permit, or in rule. The height pole must extend between three and six inches above the maximum height of the extra-legal vehicle, or load, to compensate for the affect of wind and motion. When not in the act of escorting an extra-legal move, or prerunning a route to determine height acceptance, the height pole shall be removed, tied down or otherwise reduced to legal height.
(15) Do the rules change when a uniformed off-duty law enforcement officer, using official police car or motorcycle, performs the escorting function? While the spirit of the rules remains the same, specific rules may be modified to fit the situation.

(2) What are the dimensional limits of the combination? While the overall combination is not limited by dimension, the following limits are established:
(a) Length: The length of the manufactured housing unit may not exceed seventy-five feet, including the length of the tongue.
(b) Width: The width of the manufactured housing unit must not exceed a box (base) width of sixteen feet. The unit may have an eave provided it does not extend beyond either side by:
(i) More than thirty inches for units with a box width less than sixteen feet wide; or
(ii) More than sixteen inches for a unit with a box width of sixteen feet; however, the overall width shall not, under any circumstances, exceed eighteen feet.
(c) Width exemptions: External features, such as doorknobs, window fasteners, eave cap, clearance lights, and load securing devices, that extend no more than two inches on each side of the unit, are exempt from the overall width measurement.
(d) Height: The height of the unit is limited to the actual overhead clearance of the route.
(3) What are the criteria for receiving an annual/monthly special permit versus a single trip special permit?
(a) Annual/monthly permits are issued only to dealers or manufacturers described in chapter 46.70 RCW or licensed transporters described in chapter 46.76 RCW. Use of the annual/monthly permit is restricted to the movement of housing units with a box width not exceeding fourteen feet wide, plus an eave not to exceed twelve inches, and a height not to exceed fifteen feet measured from level ground when in transit mode.
(b) Single trip permits are required when the permit applicant is not a qualified dealer or transporter as described in (a) of this subsection, or when the width of the housing unit box exceeds fourteen feet wide, the overall width exceeds fifteen feet wide, and/or the height exceeds fifteen feet measured from level ground when in transit mode. Housing units that exceed sixteen feet wide and/or sixteen feet high must also comply with the requirements of WAC 468-38-405 Superloads, prior to the issuance of a special permit.
(4) When is it necessary to include a pilot/escort vehicle(s) in the movement of a manufactured house? The requirements for a pilot/escort vehicle escorting a manufactured home are the same as those found in WAC 468-38-100, except that the use of a height measuring device (pole) on the front pilot/escort vehicle is not required until the overall height of the housing unit exceeds fifteen feet. The vehicle or load width referenced in WAC 468-38-100 is to be interpreted as overall width when measuring a manufactured home.
(5) What are the insurance requirements, and what special reporting responsibilities does the transporter have in case of an accident?
(a) Insurance requirements for the movement of a manufactured home are outlined in RCW 46.44.180.

(2) What dimensional criteria must be met before a special permit is required to move extra-legal farm implements? Self-propelled farm implements, including a farm tractor pulling no more than two implements, that exceeds sixteen feet in width, but less than twenty feet wide, 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 ability to acquire a special permit to move oversize farm implements be affected if the implement(s) is carried on another vehicle? The ability to use 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
(4))) (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 fourteen feet; or
(c) The loaded farm implement causes the hauling vehicle to exceed legal weight limits. The farm implement may weigh up to forty-five thousand pounds; however, the combined gross weight of implement and hauling unit may extend to the limits established in RCW 46.44.041 Maximum gross weights -- Wheelbase and axle factors.
If any of the 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 appropriate requirements for special permits as referenced in chapter 46.44 RCW and in other sections throughout this chapter.
(4) How does the application process for a special permit for farm implements differ from the 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 a three-month period up to one year. Once approved, the special permit may be generated from the Olympia office by facsimile or a letter of authorization will be sent allowing the applicant to acquire a 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 acquire this specific special permit? The acquisition 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) Does the 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.
(7) Are notifications of movement required? Movements of vehicles in excess of sixteen feet wide must be communicated to all department maintenance areas affected at least eight hours in advance. The communication is for the purpose of ensuring there will not be any planned activity that would restrict the move. Locations of maintenance area offices and phone listings are provided with each letter authorizing the purchase of the special permit.
(8) What safety precautions must be taken when moving extra-legal farm implements? The movement of extra-legal farm implements must comply with the following safety requirements:
(a) Oversize load signs: If the farm implement exceeds ten feet wide, 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 must comply with any published curfew or commuter hour restrictions.
(c) Red flags: If the farm implement is moving during daylight hours, and exceeds ten feet wide, the vehicle configuration must display clean, bright red flags. The flags must measure at least twelve inches square and be able to wave freely. The 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 transporting vehicle or vehicle combination by more than four feet, one flag is required at the extreme rear. If the width of the rear overhang/protrusion exceeds two feet, there must be two flags positioned at the rear to indicate the maximum width of the overhang/protrusion.
(d) Warning lights and slow moving emblem: Lamps and other lighting must be in compliance with RCW 46.37.160. In addition to the lighting requirements, RCW 46.37.160 also 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 following criteria are met:
(i) A minimum of five hundred feet is maintained between vehicles to allow the traveling public to pass safely;
(ii) If five or more vehicles are lined up behind any one of the implements, the operator must pull off the road at the nearest point wide enough to allow the vehicles to pass safely; 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 pilot/escort vehicles with farm implements? Pilot/escort vehicles must comply with the requirements of WAC 468-38-100, except for the following specific exemptions related only to special permits for moving farm implements:
(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 escort vehicle physical description, WAC 468-38-100 (10)(f) regarding use of height measuring device, and WAC 468-38-100(11) regarding passengers, when moving a farm implement off the interstate and on the following interstate segments:
(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; and
(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) A flag person(s) may be used in lieu of a pilot/escort(s) for moves under five hundred yards. This allowance must be stated on any permit that may be required for the move.
(d) 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 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 removed immediately after the move has been completed.
