734-082-0035 Pilot Vehicle(s) (1) Pilot vehicles may be needed to ensure 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 vehicle(s) must be a passenger car, pickup truck, 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 sign(s) mounted above the roofline of the vehicle. One required sign must bear the legend “OVERSIZE LOAD.” When three front pilot vehicles are required by a permit, and the load will cross the centerline of the highway, additional signs that bear the legend “REDUCE SPEED” and “MOVE RIGHT” may be required. Signs 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. Signs must be displayed only during the course of the oversize movement, and must be removed or retracted at all other times. Signs 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) must apply. Strobe lights are allowed. These lights must be mounted above the roof of the cab, be clearly visible from a distance of 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; or (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 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/or 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 Attachment 82A, revised January 2023. Attachment 82A is by reference made part of Division 82 rules, and is available from the CCD Over-Dimension Permit Unit. (3) The number of pilot vehicles required for certain movements is shown on Attachment 82A, revised January 2023, which is issued with permits requiring pilot vehicles. The Chief Engineer is authorized to alter the number of pilot vehicles from those specified in Attachment 82A depending upon local conditions, seasonal traffic, construction projects, or other considerations. The permit will reflect altered requirements. (4) The highway classification groups referred to in Attachment 82A, revised January 2023, are established and maintained by the Chief Engineer. (5) 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 traffic congestion is encountered, where traffic is controlled by signals, or where other conditions may require, the spacing will be reduced as may be required to properly safeguard the traveling public. (6) 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. (7) Duties of pilot vehicle operations: (a) Warn approaching and/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 will act as flagger to warn approaching traffic. (8) Pilot vehicles are considered to be under the direct control and supervision of the operator of the vehicle to which the permit is issued. (9) Specifically identified locations may require additional precautions. Permits may 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.
