What does a flashing yellow traffic light indicate?

Answer: B — Proceed with caution

A flashing yellow traffic light indicates that drivers should proceed with caution. This means that while you do not need to come to a complete stop, you should be alert to your surroundings and prepared to yield to any pedestrians or vehicles that may have the right of way. The flashing yellow light serves as a warning that the situation at the intersection may require drivers to pay closer attention, as conditions could be changing or visibility may not be optimal. In contrast to a steady yellow light, which signals that a signal change is coming and requires drivers to prepare to stop, a flashing yellow light emphasizes a need for caution without requiring an immediate stop. This is important for maintaining the flow of traffic while still ensuring safety for all road users.
