What is indicated by downward pointing arrows on direction signs?

Downward pointing arrows on direction signs typically indicate the direction that drivers should consider for their current lane maneuvering. When such arrows are displayed, they signal to the driver to "get in lane," helping ensure that the vehicle is positioned correctly to follow the intended path. This visual cue is essential in guiding drivers to make lane changes safely and effectively as they prepare to navigate intersections or merging areas.

The other options do not appropriately represent the specific action that downward pointing arrows convey. For instance, while "change lanes immediately" may suggest a need for lane adjustments, it lacks the clarity and positioning context provided by the downward arrows. Similarly, "proceed straight without changing lanes" and "continue on the current lane" might mislead drivers into ignoring the directional guidance that is necessary for safe navigation in the presence of such signs.
