(a)   No person shall operate or move any crawler-type tractor, steam shovel, derrick, roller, or any equipment or structure having a normal operating speed of six or less miles per hour or a vertical body or load clearance of less than nine inches above the level surface of a roadway, upon or across any tracks at a railroad grade crossing without first complying with divisions (a)(1) and (2) of this section.
      (1)   Before making any such crossing, the person operating or moving any such vehicle or equipment shall first stop the same, and while stopped, the person shall listen and look in both directions along the track for any approaching train and for signals indicating the approach of a train, and shall proceed only upon exercising due care.
      (2)   No such crossing shall be made when warning is given by automatic signal, crossing gates, or a flagperson, or otherwise of the immediate approach of a railroad train or car.
   (b)   If the normal sustained speed of the vehicle, equipment, or structure is not more than three miles per hour, the person owning, operating, or moving the same shall also give notice of the intended crossing to a station agent or superintendent of the railroad, and a reasonable time shall be given to the railroad to provide proper protection for the crossing.  Where the vehicles or equipment are being used in constructing or repairing a section of highway lying on both sides of a railroad grade crossing, and in this construction or repair it is necessary to repeatedly move the vehicles or equipment over the crossing, one daily notice specifying when the work will start and stating the hours during which it will be prosecuted is sufficient.
