What is indicated by two opposing arrows on a traffic sign?

Answer: B — Traffic may flow on both sides

Two opposing arrows on a traffic sign signal that traffic may flow on both sides. This visual representation indicates that vehicles can travel in both directions on a certain stretch of the road. It is essential for drivers to be aware of such signage, as it helps in maintaining safe navigation, particularly in areas that may involve narrower roads or two-way streets where vehicles need to be cautious when passing each other. In contrast, options suggesting that traffic only flows in one direction or that the road is closed would not align with the meaning of opposing arrows. Additionally, a detour typically involves an alternate route due to road conditions or construction, which would usually not be indicated by opposing arrows but rather specific detour signs. Thus, understanding the significance of opposing arrows in traffic signage is critical for ensuring safe and efficient driving.
