What does an arrow mark indicate regarding traffic movement?

An arrow mark on the roadway is a clear visual indication that directs traffic movement in a specific way. When an arrow points in a particular direction, it signifies that all vehicles should proceed in that direction. This helps to organize traffic flow, ensuring that drivers understand where they are permitted to go and reducing confusion at intersections or lanes that branch out.

In contrast, stopping at a signal is usually indicated by traffic signals rather than specific markings on the road. Pedestrian movement has its own set of signs and signals to indicate where and when it is safe to cross, which is distinctly different from the direct instructional nature of an arrow for vehicular traffic. Lastly, the regulation regarding commercial vehicles typically requires specific signage or markings that indicate restrictions based on vehicle type, rather than the directional guidance provided by an arrow mark. Thus, the presence of an arrow is a straightforward directive for all traffic, ensuring adherence to the intended route.
