Having passed an Approach signal, you observe the signal at the next control point displayed as a Green over two Reds. How will you proceed?

• A. Restricted speed
• B. Stop
• C. Top speed
• D. Reduce to 30 mph

Answer: (C)

In this signaling setup, the top light determines the main instruction for the next block, and the overall speed authority comes from that top aspect. A green top light means you are authorized to proceed, and in this configuration the two red lights below do not impose a stop or a reduced speed limit. Therefore, after passing the Approach signal, you can continue at track speed for the upcoming block, assuming there are no other posted restrictions or temporary speed limits elsewhere on the route.

If the top light were red or yellow, or if a specific speed sign were present, you would adjust accordingly. But with a green top light, the best course is to maintain normal, track-speed movement while remaining vigilant for any other speed restrictions that might be published along the way.
