What does a flashing yellow light indicate?

A flashing yellow light signals drivers to proceed with caution. This means that when you encounter a flashing yellow light, you should slow down and be alert for any potential hazards, including pedestrians, cyclists, or other vehicles that may be in or approaching the intersection. The warning indicates that while it is safe to continue through the intersection, you must remain vigilant to ensure safety, particularly if conditions are less than ideal or if there are other traffic control devices present.

The other options do not accurately reflect the purpose of a flashing yellow light. Stopping immediately would be appropriate for a red light, while speeding up is not safe or advisable as it could increase the risk of an accident. Turning left or right carefully is a general precaution but does not specifically relate to the meaning of a flashing yellow light, which emphasizes caution rather than a specific maneuver.
