Pilot Vehicles

(1) Pilot vehicle(s) may be needed to insure the safety of the traveling public when vehicle and load movements involve excessive width, height, length, or projections to the front or rear of vehicles or combinations of vehicles. The configuration of such pilot vehicles(s) must be a passenger car, pick-up, truck, or truck-tractor of legal size and weight. A pilot vehicle may not tow another vehicle.

(2) Pilot vehicles escorting oversize loads or vehicles are required to have the following:

(a) Warning signs mounted above the roofline of the vehicle. This sign must bear the legend “OVERSIZE LOAD.” The sign must be at least five feet wide by ten inches high; have black letters eight inches high with one-inch brush stroke in accordance with Federal Highway Administration series B, on highway yellow background. The sign must be displayed only during the course of the oversize movement, and must be removed or retracted at all other times. The sign must be clean, legible, and mounted adequately to afford full view at all times, when in use, to the front or rear depending upon location of pilot vehicle or relative to the oversize unit;

(b) Warning lights are required in addition to those lights that may otherwise be required by law. The warning lights must be displayed only during the course of the oversize movement, and at all other times the requirements found in ORS 816.350(7) will apply. Strobe lights are allowed. These lights must be mounted above the roof of the cab, be clearly visible from 500 feet, have a minimum of 30 flashes per minute and be either:

(A) Two flashing amber lights as widely spaced laterally as is practical;

(B) Revolving type amber light(s); or

(C) Amber type strobe light(s) with 360 degree visibility.

(c) Two-way radio communications between the oversize vehicle and the pilot vehicle(s) must be maintained at all times;

(d) Two 18-inch-square red or fluorescent orange flags mounted on three-foot length staffs must be carried by each pilot vehicle. The pilot vehicle operator will use the flags to warn oncoming or overtaking traffic when the oversize unit is stopped and obstructing traffic;

(e) Eight safety flares or reflectors. Safety flares may not be used when the movement involves hazardous materials; and

(f) For a load exceeding 14 feet 6 inches high, an over-height pole adequate to determine load clearance is required if the permittee has not provided the department with a signed official ODOT form assuming all liability for any damage that may occur during an over-height movement. Instructions for over-height pole use are found on Permit Attachment 75-A.

(3) The number of pilot vehicles required for certain movements is shown on Permit Attachment 75-A, which is issued with permits requiring pilot vehicles. The Chief Engineer is authorized to alter the number of pilot vehicles from those specified in Permit Attachment 75-A depending upon local conditions, seasonal traffic, construction projects, or other considerations. The permit will reflect altered requirements. Further, units with an overall width not exceeding 12 feet that meet the warning lights requirements described in 734-075-0040(2) and (3) are exempt from rear pilot car requirements on Group 1 Highways unless specifically required by the permit or Chief Engineer.

(4) Permit Attachment 75-A is available from the Motor Carrier Transportation Division, Over-Dimension Permit Unit.

(5) The highway classification groups referred to in Permit Attachment 75-A are established by and maintained by the Chief Engineer.

(6) Positioning of pilot vehicles — Unless specified otherwise, the pilot vehicle(s) must be positioned ahead of (when one is required) or to the front and rear of (when two or more are required) the oversize unit at a distance of 300 feet to 500 feet from the unit. In areas where increased traffic congestion is encountered, where traffic is controlled by signals, or where other conditions may so require, the spacing will be reduced as may be required to properly safeguard the traveling public.

(7) When for any cause the oversize unit is stopped and occupies or encroaches onto the highway’s travel lane, the pilot vehicle(s) must be positioned to warn and safeguard other traffic approaching from any direction from which visibility or sight distance may be limited.

(8) Duties of pilot vehicle operations:

(a) Warn approaching or overtaking traffic of the unit’s presence on the highway to provide a maximum of protection and safety for the traveling public; and

(b) When encountering bridges, structures, tunnels, or other locations where clearances may be limited to the extent that normal two-way traffic cannot be maintained, the pilot vehicle operator must signal by hand or radio to the towing vehicle driver when the oversize unit can proceed without conflict to approaching traffic. As the oversize unit then proceeds through such areas of impaired clearance, the pilot vehicle operator must warn approaching traffic.

(9) Pilot vehicle(s) are considered to be under the direct control and supervision of the oversize vehicle operator.

(10) Specific identified locations may require additional precautions. Permits will specify locations that require certified flagging to be conducted. The flagging must be conducted in accordance with the standards in the Manual on Uniform Traffic Control Devices as adopted in OAR 734-020-0005.

General Permit Provisions

(1) Posted Load Limits: Notwithstanding the weights or dimensions allowed under a permit, the posting of any highway or structure to reduce weights or dimensions will modify the limits allowed under the permit.

(2) Impaired Clearance: Full responsibility for determining adequate clearance, both vertical and horizontal is hereby imposed upon the permittee and the driver of equipment having a width or height in excess of the legal limit. When the vertical or horizontal clearance of any bridge or structure is impaired to the extent that full two-way traffic cannot be maintained, the permittee must provide a pilot vehicle for the purpose of preventing approaching vehicles from entering the bridge or structure while it is impaired by the movement covered by this permit.

(3) Spacing Interval: Two or more vehicles required to display warning signs must maintain a distance of one-half mile between combinations traveling in the same direction, except when overtaking or passing or in areas where increased traffic congestion is encountered, where traffic is controlled by signals or where other conditions may so require. All slow-moving lanes and turn-outs must be used to allow following traffic to pass.

(4) Bond — Highway Damage: Permittee will be held responsible and liable for any and all damage to or destruction of any highway or any highway structure occasioned by the movement over said highways, and hereby agrees to reimburse the Department of Transportation (Department) for the cost or expense of repairing or restoring any highway structure damaged, or destroyed; such reimbursement to be made by the permittee within ten days after being billed for the same by the Department. When requested to do so, permittee must furnish the State either a certified check or a surety bond, in any amount to be specified by the Department to guarantee the payment of claim for damages which may result from movement of an unusually large or heavy nature.

(5) Insurance: Permittee will also be held responsible and liable for any and all injury to persons or damage to property resulting from the movement on said highways, and will indemnify and hold harmless the State of Oregon, and Oregon Transportation Commission, its members, officers, and employees, jointly and severally, from liability in the event that such injury or damage may occur. In this connection, the granting authority may require the permittee to furnish to the Department evidence of satisfactory public liability and property damage insurance, in amounts as may be required by the Department, and evidence of satisfactory indemnity insurance indemnifying the State of Oregon and its Transportation Commission, its members, officers, and employees, jointly or severally against liability in the event of any injury or accident occurring by reason of said permittee’s operations on a state highway. This permit will automatically terminate, and be of no force and effect in the event that any insurance filed under this provision is canceled or is allowed to lapse.

(6) County Roads and City Streets: This permit does not authorize operations over county roads or city streets unless specifically noted. To operate over a county road a permit must be obtained from the county authority having jurisdiction over the road; likewise, to operate over a city street other than a state highway route, a permit must be obtained from the proper city authority.

(7) Cancellation: This permit may be canceled at any time by the granting authority upon proof satisfactory to it that the permittee has violated any of the terms of the permit or that the permit was obtained through misrepresentation in the application or when in the judgment of the granting authority the public interest requires cancellation (ORS 818.220).

(8) Rear-view Mirrors: A Power unit must be equipped with a minimum of two rear view mirrors positioned to allow the operator to view the rear of the last vehicle of the combination and to see down each side of the vehicle(s) being transported. Mirrors may exceed authorized width only as much as required to provide the operator the required view to the rear and must be retracted to legal width at all other times.

(9) It is the responsibility of the motor carrier to notify the Over-Dimension Permit Unit in the event of striking a structure in the course of a movement. In addition to any other notification required by law, within 24 hours of striking a structure, the motor carrier must initially report the incident to the Over-Dimension Permit Unit pager at (503) 588-9610. The motor carrier will be contacted and provided with a form to report the incident and within 72 hours of the contact must return the completed form by fax to (503) 378-2873 or delivery to the Over-Dimension Permit Unit at 550 Capitol St. NE, Salem, OR 97301-2530.
