What does a flashing yellow light mean?

Answer: C — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. This signal serves as a warning that there may be a potentially hazardous situation ahead or that the driver should be alert for changes in traffic conditions. It does not require a complete stop, as a red light would, but instead prompts the driver to be vigilant, potentially yielding to other traffic or pedestrians while continuing through the intersection or area. In contrast to a flashing yellow light, a steady yellow light would signal the approach of a red light, urging drivers to prepare to stop. A flashing yellow light emphasizes the need for caution rather than a normal driving speed, making it essential for drivers to stay alert and ready to react appropriately to any unforeseen circumstances.
