OAR 734-075-0085: 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) 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. (5) 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). (6) 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. (7) In addition to any other notification required by law, within 24 business hours of striking a structure, the motor carrier must report the incident to the Over-Dimension Permit Unit at (503) 373-0000.
