When encountering a flashing yellow light, what should a driver do?

When encountering a flashing yellow light, the appropriate action for a driver is to slow down and proceed with caution. A flashing yellow light indicates that the driver should be aware of potential hazards or a situation ahead that requires careful attention. It serves as a warning rather than a stop signal, suggesting that while it is safe to continue driving, the driver should be alert and ready to adjust their speed or be prepared to yield if necessary.

This instruction is crucial for ensuring safety as it prompts drivers to remain vigilant for pedestrians, cyclists, or other vehicles that may be present in or near the intersection. It also underscores the importance of awareness in driving situations, allowing for better decision-making based on the current traffic conditions.

The other options do not align with the appropriate action for a flashing yellow light. Coming to a complete stop is unnecessary unless indicated by other traffic signals or signs, and speeding up to clear the intersection or ignoring the signal could lead to dangerous situations, including accidents.
