Which Of The Following Is NOT A Standard Hand Signal Listed In The 7 Hand Signals?

• A. Turn On Headlights
• B. Stop
• C. Proceed
• D. Back

Answer: (A)

Hand signals communicate movement commands to the engineer using clear, visible arm and hand gestures. The standard signals cover actions like stopping, proceeding, and backing the train, all performed with specific motions that can be seen from a distance. Turning on headlights is not a gesture; it’s a control action inside the locomotive cab. Since it isn’t a gesture used to communicate movement on the track, it isn’t part of the standard hand signals. The other options—Stop, Proceed, and Back—are all basic, recognized signals used to direct the train’s actions.
