What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. This means that while you can continue driving, you need to be alert to potential hazards, such as pedestrians crossing, other vehicles making turns, or changing road conditions. It's a signal to be more vigilant and prepared to react appropriately to any situation that may arise.

In contrast, the other choices misrepresent the meaning of a flashing yellow light. For example, a solid red light requires a complete stop, while yielding to all traffic is relevant for certain intersections or signs, but a flashing yellow doesn’t invoke those rules. Making a U-turn is not related to a flashing yellow signal, as it pertains to different traffic situations. Understanding the meaning of a flashing yellow light is crucial for safe navigation on the road.
