What does a Blue Signal signify?

• A. A blue flag, blue light, or blue tag indicating workers are on, under or between equipment.
• B. A signal indicating track occupancy.
• C. A bulletin order.
• D. A cab signal.

Answer: (A)

Blue signals are used to protect workers who are on, under, or between equipment. A blue flag, blue light, or blue tag indicates that personnel are in or around the equipment, so movement of the train or the equipment itself is restricted until the protection is removed or authorized. This protects workers in the area and is different from track occupancy signals (which indicate the track is occupied), bulletin orders (written directives), or cab signals (onboard speed/authority indications).
