(a) When one vehicle is towing another, the drawbar or other connection shall be of sufficient strength to pull all weight towed thereby, and such drawbar or other connection shall not exceed 15 feet from one vehicle to the other, except that the connection may be longer between any two vehicles transporting poles, pipes, machinery, or other objects of such structural nature as cannot readily be dismembered.
(b) When one vehicle is towing another and the connection consists of a chain, rope, or cable, there shall be displayed upon such connection a white flag or cloth not less than 12 inches square.
(c) Trailers shall not be operated, permitted to be operated, caused to be operated, or parked on public highways without the safety chain or chains (stay chain or cable) securely coupled to the motor vehicle to which it has been coupled for towing. The safety chain or chains shall not be coupled to the same coupling of the towing vehicle to which the tow bar is coupled. Each chain or cable and its accompanying coupling and mounting devices shall have an ultimate strength equal at least to the gross weight of the trailer. No more slack shall be left in the safety chain or cables than shall be necessary to permit proper turning. The safety chain or cable shall be so connected to the trailer and towing vehicle, and also to the tow bar so as to prevent the tow bar from dropping to the ground in the event the tow bar or coupling should fail.
(d) No asphalt kettle containing hot liquid asphalt shall be towed or otherwise moved upon the highway, unless the kettle is no more than one-half full of liquid asphalt, the top has been securely fastened, and chunks of cold, hard asphalt have been added to the liquid asphalt in sufficient quantities to cool the asphalt to a semisolid state and minimize splashing. In no event shall an asphalt kettle be towed or moved along the public highway while the heating element is operating.
