Before Going On, Under, Or Between Engines And/Or Cars, What Must Workmen Display?

• A. Blue Signal Protection
• B. Red Flag
• C. White Light
• D. Stop Sign

Answer: (A)

Before going on, under, or between engines and/or cars, workers must display blue signal protection. This blue signal warns approaching crews that someone is on or around the equipment and needs protection from movement, so trains and other workers proceed with caution or stop as needed. The blue flag or blue light is the standard way to indicate this protection, whether it’s daytime (flag) or nighttime (blue light). Red flags, white lights, and stop signs serve different signaling purposes and do not provide the required protection signal in this situation.
