A color light, color position light, or semaphore signal that conveys Stop as its most restrictive speed and does NOT have a P marker, C marker, APP marker, or a G marker is known as what?

• A. Absolute Signal
• B. Intermediate Signal
• C. Stop Signal
• D. Distant Signal

Answer: (A)

Absolute signals are fixed signals that enforce a hard stop at the entrance to a block or interlocking. When a color light, color position light, or semaphore shows Stop as its most restrictive speed and has no P, C, APP, or G markers, it is classified as an Absolute Signal. The absence of those markers means there’s no permissive condition or special clearance attached to the aspect; you must come to a full stop and only proceed when cleared. Distant signals, by contrast, merely warn about the status of the next fixed signal and do not authorize movement. This description matches the defining behavior of an Absolute Signal, making it the correct term.
