What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. This signal alerts drivers that there may be a potential hazard ahead or that they need to be mindful of their surroundings. It doesn’t require a stop, but it does emphasize the need for careful observation and decision-making, allowing drivers to navigate the situation safely.

The other options imply actions that are not appropriate in response to a flashing yellow light. Stopping immediately is unnecessary and could disrupt traffic flow, while speeding up to clear an intersection poses a risk of accidents. Turning left or right is not designated by a flashing yellow light specifically, which could lead to confusion about the intended actions at the intersection. Thus, the emphasis on caution allows drivers to maintain safety while proceeding through an area where attention is especially needed.
