The term CONSTRUCTION ZONE SIGHT is composed of two words, CONE (4 letters) and TRAFFICCONE (11 letters). A CONE is a three-dimensional object with a circular base and a pointed top, usually made of plastic or rubber. It is often used to mark off areas in construction zones, as well as for traffic control. A trafficcone is a type of CONE that is specifically designed for use in traffic control. It is usually taller than a regular CONE and has reflective material on it to make it more visible at night.
