The direction of traffic refers to the flow of vehicles, pedestrians, and other forms of transportation on a road or pathway. It is determined by the designated lanes, signs, and signals that guide the movement of individuals and vehicles in a safe and organized manner. This can vary depending on the country, with some following a right-hand traffic system and others following a left-hand traffic system. The direction of traffic is crucial for maintaining order and preventing accidents on the road, making it an essential aspect of transportation infrastructure.
