How should you respond to a signal displaying a flashing yellow aspect?

• A. Be prepared to stop at the next stop signal unless authorized to proceed under specific instructions.
• B. Accelerate to clear the segment.
• C. Proceed as normal.
• D. Treat it as a steady green.

Answer: (A)

A flashing yellow signal tells you to proceed with caution and be prepared to stop at the next stop signal unless you’re specifically authorized to proceed under a timetable or other instructions. This means you should slow down, stay alert for the next signal, and be ready to stop if that signal requires it. It’s not a green or normal proceed indication, and you shouldn’t speed up or ignore the caution. The instruction to be prepared to stop at the next signal is the key takeaway, with a possible exception only if a supervisor or timetable explicitly authorizes continuing under specific conditions.
