What does a flashing yellow signal mean?

Answer: B — Proceed with caution; yield to oncoming traffic

A flashing yellow signal indicates that a motorist should proceed with caution. This warning signal alerts drivers to slow down and be prepared to yield to any oncoming traffic or pedestrians in the intersection or road area. It is a reminder that while you can continue moving, you must do so carefully and be aware of your surroundings, as there may be hazards present that require your attention. The other choices suggest actions that are inappropriate for a yellow flashing signal. Stopping and waiting for a green light may not be necessary, as the flashing yellow does not indicate a complete stop is required. Increasing speed to cross quickly may lead to dangerous situations, as it ignores the caution aspect of the signal. Disregarding the signal entirely would compromise safety and goes against traffic laws. Thus, proceeding with caution and yielding where necessary is the correct interpretation of a flashing yellow signal.
