What does a flashing green traffic light indicate?
Answer: A — Proceed with caution.
A flashing green traffic light is used in areas where there is not much traffic and provides a signal for drivers to proceed with caution. It indicates that drivers should be aware of potential hazards and be prepared to stop if necessary. Unlike a solid green light, a flashing green light does not give the right-of-way to drivers. Therefore, options B, C, and D are incorrect as they do not accurately describe the purpose of a flashing green light.
