What should you do when the ramp meter display is dark or not emitting a red or green light?

• Stop and wait for further instructions.
• Proceed without stopping and enter the freeway by merging or yielding as normal conditions allow.
  Explanation:

  "When a ramp meter is displaying a circular red display, vehicles facing the red light must stop. When a ramp meter is displaying a circular green display, a vehicle facing the green display may proceed to merge onto the freeway. When the display is dark or not emitting a red or green display, a vehicle may proceed without stopping and enter the freeway by merging or yielding as normal conditions allow."
• Honk the horn to signal confusion.
• None of the above.
