What does a flashing yellow light indicate?

Answer: B — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. This signal is used to alert drivers that they should be aware of potential hazards or changing conditions ahead. It encourages vigilance, as it might be signaling an intersection, a pedestrian crosswalk, or a construction zone where additional care is needed. Unlike a solid yellow light, which warns of an impending red light, the flashing yellow does not require drivers to stop, but it does mean they should slow down and be prepared to react to other vehicles, pedestrians, or obstacles in the roadway. This approach fosters safer driving behaviors by reminding drivers to remain alert and responsive rather than maintaining their standard speed or assuming clear passage.
