What does a sign indicating "one-way traffic" mean?

A sign indicating "one-way traffic" signifies that vehicles are permitted to travel in a single direction only. This means that drivers must adhere to the specified direction and cannot drive against the flow of traffic. One-way traffic signs are crucial for maintaining order and safety on the roads, as they help prevent confusion and potential collisions by clearly directing how vehicles should navigate the area.

Understanding this sign is important for safe driving, especially in urban environments where the layout might involve narrow streets or intersections. Recognizing that traffic flows only in one direction helps drivers anticipate the movement of other vehicles and follow the appropriate route, thereby enhancing traffic efficiency and reducing the likelihood of accidents.

The other options depict scenarios that do not relate to the function of a one-way traffic sign. For example, signs indicating pedestrian-only zones or specific parking regulations are designed to address different aspects of road use and do not pertain to the direction of vehicle travel.
