1. (d) The use of a certified escort vehicle in the rear in lieu of a warning sign may be required if the use of such vehicle would provide more effective warning or would be more convenient to the permittee.
2. (e) No vehicle operating under a special hauling permit may travel on a road or cross a bridge if the gross vehicle weight exceeds the posted limit.

3. (f) Overhead wires, cables, signal or traffic lights, limbs of trees or overhead structures shall not be disturbed without first obtaining permission from the owners thereof and movements shall not be commenced until after such consents are obtained.

   1. (1) Special permit vehicles operating on four lane or divided highways shall be driven in the right-most lane for traffic, except the right lane must exit. Vehicles on two lane highways shall pull off of the pavement whenever possible to allow traffic from both directions to pass. Permit vehicles shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety.
   2. (2) Special hauling permit vehicles must travel at least 2,000 feet apart unless specified on the permit.
   3. (3) Loads must be adequately secured to the vehicle.

   4. (4) No movements are allowed upon any highway when the visibility is limited by atmospheric or other conditions so as to make travel hazardous for any vehicle. No travel is allowed when any person, vehicle or highway is not clearly discernible at a distance of 1,000 feet. No travel is allowed when the surface of the highway is made hazardous by rain, sleet, snow or ice. No travel is allowed when the surface of the highway is made hazardous by fog, flood or wind. During such periods, vehicles may be halted by the Department of Transportation, State Police or other authorized agency and ordered removed from the highway.

      (h) Night moves.

      In addition to the requirements contained in section 154-1.14 of this Subpart, the following requirements are applicable to nighttime (period between one-half hour after sunset to one-half hour before sunrise) movements of over width and/or over length loads. For over width loads uniform in width, amber lights must be placed on the forward corners of the load and red lights on the rear corners. If the load is over width for its entire length with a wider portion near the middle of the load, red lights must be placed at the rear corners, and amber lights must be placed at the front corners, and on each side at the extreme width limits of the load. If the load is nonuniform in width with the over width portion at the rear extremity of the load, red lights must be placed on the sides of the load at the location of its extreme width. If the load is nonuniform in width with the over width portion at the front, amber lights must be placed on each side of the load at the location of its extreme width. If the load is only over length and the overhang of the load is less than two feet, red lights must be placed on the rear side corners of the load. If the load is over length by greater than two feet, red lights must be placed on the rear corners of the load and amber lights must be placed at least every six feet along the side of the overhang portion of the load. The diagrams below indicate the correct placement of lights for night moves.
