Dozer blades shorter than 14′ wide may be hauled without being detached provided the dozer is firmly supported. If buckets, blades, counterweights, etc., are easy to remove, they must be removed, but can be hauled with the load. Blade can be detached and hauled with the dozer on same trailer if the load would be overweight with or without the blade. It should be stated on the permit. On wide loads, side mirrors must extend far enough to avoid view being blocked by the load.
SIGNS, FLAGS & LIGHTS: "Oversize Load” or "Wide Load” signs required on front of towing unit and on rear of load for any oversize, overweight or overweight only load. Red flags at least 12″ square must be affixed to front right and left sides of towing unit and to each corner of the load. Towing vehicles pulling oversize loads that exceed 12′ wide may display an amber rotating flashing beacon atop the cab.
