If more than one indication is possible, and all indications are more favorable than Stop and Proceed, trains may proceed:

• A. Proceed with caution under dispatcher's instruction.
• B. Only after a Stop signal.
• C. Only when the Stop and Proceed is applicable.
• D. As though a Restricting Signal were displayed.

Answer: (D)

When more than one indication could apply and all are more favorable than Stop and Proceed, you proceed as though a Restricting Signal were displayed. This keeps you operating under the safety limit that applies when there’s any ambiguity, rather than assuming full clear track. A Restricting Signal means you move at restricted speed and be prepared to stop at the next signal or occupancy. By defaulting to that condition, you ensure you won’t exceed a safe pace or be caught off guard by a later restriction, even if some indications could seem more permissive. The other options would require actions not warranted by the available indications in this scenario: no dispatcher instruction is needed, no Stop signal is required, and you don’t wait for a Stop and Proceed when the indications are all more favorable than that.
