A variety of cones (and cone sizes) are used on highways. A common small triangular orange cone with reflective strips is typically made of 5 lb. or 7 lbs of PVC plastic.
Often the taller tube cones are used on highways, and these too can range in size. Many are made from durable high density polyethylene and (including the rubber base) weigh 12lbs to 20lbs.
