When driving towards a yellow arrow, what should you be cautious of?

When approaching a yellow arrow, it is crucial to understand that it serves as a warning signal indicating that the traffic light is about to change, typically to red. Therefore, being cautious of oncoming traffic is vital, as vehicles may be adjusting their speed and direction in anticipation of the light change. This situation can be particularly hazardous, as drivers might be rushing to clear the intersection before the light turns red, which can lead to collisions if you’re not alert to their movements.

While the other options may present valid concerns in different contexts (such as road closures or blocked lanes), the immediate reasoning for being cautious when encountering a yellow arrow pertains significantly to the behavior of oncoming traffic and the potential risks it introduces at that moment. Understanding this helps enhance overall driving safety at intersections.
