If the signal at the next control point after an Approach signal shows Green over two Reds, what is your speed?

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

Answer: (C)

The signal aspects tell you how fast you’re allowed to run and what to expect ahead. An Approach signal asks you to be prepared for the next signal, but the actual speed you may run is governed by the next signal’s aspect. If the next control point shows Green over two Reds, that indicates a clear route ahead with no speed restriction, so you may proceed at timetable/top speed until you reach the next signal or limit.

That’s why top speed is the best answer here. Stopping would be required only if the next signal showed red; a restriction or a 30 mph limit would be indicated by a different aspect or speed sign, not by Green over two Reds.
