What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. It serves as a warning to alert drivers that they may need to be more vigilant as they approach an intersection or a hazard. The flashing yellow light does not require a complete stop, but it is important for the driver to assess the situation carefully and be prepared to yield to any oncoming traffic or pedestrians.

In contrast, the other options suggest inappropriate actions that would not align with safe driving practices. Stopping immediately or waiting for a green light would not be necessary when encountering a flashing yellow light, as it does not indicate that vehicles must stop. Similarly, speeding up to cross quickly is dangerous and contradicts the caution that the flashing light is designed to invoke. It is essential for drivers to recognize the implications of traffic signals and adjust their driving behavior accordingly for safety.
