What should a driver do when encountering a flashing yellow light?

Answer: B — Proceed with caution

When a driver encounters a flashing yellow light, the appropriate response is to proceed with caution. This signal typically indicates that drivers should be aware of potential hazards in the area and exercise heightened alertness as they move through the intersection or past the light. Flashing yellow lights are often used in situations where there may be increased pedestrian activity, road work, or any other condition that might necessitate careful navigation. It is a reminder for drivers to reduce speed and prepare to react to any unforeseen circumstances, ensuring safety for everyone on the roadway. Stopping immediately would not be correct unless required by additional signage or conditions since a flashing yellow does not mean stop but rather proceed with caution. Accelerating through the intersection undermines the very purpose of the warning and could lead to dangerous situations. Ignoring the light altogether poses an even greater risk to both the driver and others, leading to potential accidents. Thus, proceeding with caution is the safest and most responsible action in response to a flashing yellow light.
