Blue signals indicate:

Blue signals indicate:

• A. Workmen are on, under, or between rolling equipment.
• B. Signals are out of service.
• C. Track maintenance in progress.
• D. The train has the right of way.

Answer: (A)

Blue signals are used to protect workers who are on or near the track or rolling equipment. When a blue signal is present, it means a work crew member is on, under, or between cars and needs protection from moving equipment. Because of that, you must not pass beyond the blue signal and should obtain proper clearance from the person in charge of the protection before moving. This safety indication is specific to workers’ presence and does not indicate that signals are out of service, that track maintenance is in progress, or that the train has the right of way.
