What does a flashing yellow light indicate?

A flashing yellow light signals drivers to proceed with caution. This means that while it is safe to continue driving, drivers need to be alert and prepared to react to any potential hazards or situations, such as pedestrians crossing or vehicles suddenly stopping. It does not require a complete stop, so drivers should still slow down and evaluate their surroundings for safety before moving through the intersection or area.

The other responses imply actions that are not appropriate for a flashing yellow light. Stopping completely is unnecessary, as the light indicates that it's permissible to move forward with caution. Speeding up is unsafe, as it doesn't take into account the potential hazards indicated by the flashing light. Additionally, turning left immediately is also not a prescribed action for a yellow light, as that action would depend on the specific road conditions and traffic.
