What does a flashing yellow traffic light indicate?

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal alerts motorists that they must be careful and be aware of their surroundings, as there may be situations requiring quick decisions or adjustments to their driving. It signals that an intersection or a potentially hazardous condition is near, and drivers should be prepared to react appropriately to ensure safety, such as yielding to any other road users or being ready to stop if necessary.

In contrast, stopping immediately would be suggested by other signals, like a solid red light. Yielding to oncoming traffic would apply in specific situations, typically at stop signs or a solid yellow light but not a flashing yellow. Similarly, turning left does not necessarily relate to this signal, as a flashing yellow light applies broadly and doesn't specifically indicate a turn. Thus, the proper response to a flashing yellow light is to proceed with caution, as indicated in the correct choice.
