What is required when delayed within a block in CTC limits when PTC is not in effect?

• A. Proceed immediately to normal speed.
• B. Proceed prepared to stop at the next signal until the next signal is visible and that signal displays a proceed indication.
• C. Stop in place and wait for instruction.
• D. Notify the dispatcher and expect a new route.

Answer: (B)

When PTC isn’t in effect, operating inside CTC limits requires you to proceed prepared to stop at the next signal until you can see that signal and it shows a proceed indication. This safety rule keeps you from rushing through a block if conditions changed while you were delayed, since there’s no automatic enforcement of movement authority. You must be ready to stop at the next signal if it’s red or not yet visible, and only continue once you can clearly see the next signal and it indicates you may proceed.
