What does a flashing yellow traffic signal mean?

Answer: B — Proceed with caution

A flashing yellow traffic signal indicates that drivers should proceed with caution. This warning signal alerts motorists to be aware of their surroundings and to be prepared to yield to other vehicles and pedestrians as necessary. It signifies that they should slow down and be alert to any potential hazards or changes in traffic flow ahead, rather than coming to a complete stop as would be required with a red signal. In contrast to the other options, a flashing yellow does not instruct drivers to stop immediately or yield specifically to pedestrians, nor does it direct them to make a right turn. The emphasis is on cautious movement, implying that while it is safe to continue driving, one must do so with heightened awareness of the surroundings and possible obstacles. This understanding is critical for ensuring safety both for the driver and others on the roadway.
