In West Africa, two or three variants of the European system of signs are followed, although at least a few signs of the American system have also been introduced. With regard to traffic light signals, both two-light and three-light systems are known as to road markings, in urban areas there have been introduced delimitation lines for parking (or no-parking) centre lines and stop lines Much attention seems to have been paid, at least in some countries, to proper methods of hand-signaling traffic police.
