What does a flashing yellow light at an intersection indicate?

A flashing yellow light at an intersection signals that drivers should proceed with caution. This means that while it is safe to continue through the intersection, drivers must be aware of their surroundings and be prepared to stop if necessary. The flashing yellow light often indicates that there may be a hazard ahead or that traffic conditions are changing, so reduced speed and increased vigilance are essential to ensure safety.

In this context, the other choices present actions that do not align with the intent of a flashing yellow light. Stopping immediately or yielding only to pedestrians implies an obligation that does not exist with a caution signal, while driving at normal speed disregards the need to remain alert and responsive to any potential dangers at the intersection.
