What is the associated cab code for a slow clear?

• A. Cab code A
• B. There is no cab code
• C. Cab code B
• D. Cab code C

Answer: (B)

The thing being tested is how cab signaling uses codes with specific signal indications. A cab code is only used when a signal indication carries a coded command for the cab. Slow clear is an indication that the signal is effectively clear but with a reduced speed, and it does not transmit a separate coded instruction. So there is no associated cab code for slow clear—the cab code field remains unused for that indication. If other signal aspects do convey a coded instruction, those would have a cab code, but slow clear does not.
