What does a flashing yellow traffic light mean?

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal alerts drivers to be aware of their surroundings, as they may encounter potential hazards or need to yield to other traffic or pedestrians. The flashing yellow light is not a command to stop; rather, it encourages drivers to reduce their speed and approach the intersection or hazard with increased vigilance.

In contrast, the options suggesting an immediate stop or increasing speed do not align with the meaning of a flashing yellow light, which is designed to ensure safety by prompting caution without requiring a complete halt. The option suggesting preparing to stop is also misleading, as the light does not indicate an immediate need to stop but rather to be aware and cautious of the actions that may need to be taken based on the situation.
