If a light is absent, a white light is displayed where a colored or lunar light should be, or additional colored or lunar lights are displayed, how must you regard the signal?


  1. Stop, and then proceed at restricted speed and report the issue to the dispatcher
  2. Regard that signal as displaying the most restrictive indication it can give
  3. Proceed at maximum authorized speed and report the issue to the dispatcher
  4. Proceed at reduced speed until you pass the next governing signal

Answer: Regard that signal as displaying the most restrictive indication it can give
Feedback:
If a light is dark or just a lightbulb without a lens is seen, regard that block or interlocking signal as displaying the most restrictive indication it can give. In most cases, this indicates either stop or restricted speed.
