What does a flashing yellow traffic signal indicate?

Answer: B — Proceed with caution

A flashing yellow traffic signal indicates that drivers should proceed with caution. This means that while it is safe to continue through the intersection or area, drivers need to be aware of their surroundings and look out for any potential hazards, such as other vehicles or pedestrians. In contrast, options that suggest stopping or yielding are not applicable here. A flashing yellow does not require a complete stop; instead, it communicates to drivers that they should reduce speed and be prepared to react to any unforeseen circumstances. Drivers should always remain vigilant when moving through an area with a flashing yellow light, as it signals a need for increased awareness rather than simply proceeding without caution.
