When is it appropriate to dim the headlight to allow the passing of hand signals?

Dimming the headlight to allow the passing of hand signals is primarily a safety measure. It ensures that the crew members can clearly see and interpret the signals being given, which is crucial for maintaining safe operations on the tracks. When passing through areas with work crews or other employees, limiting the brightness of the headlight can help prevent temporary blindness or distraction, allowing the signals to be seen clearly.

While dimming may occur during daylight hours or be left to the discretion of the conductor, these situations can vary significantly. The key point is that dimming should always prioritize safety for employees, especially when hand signals are in use, ensuring operational effectiveness and minimizing the risk of accidents. Therefore, the appropriate action is to dim the headlight whenever safety for employees requires it, reflecting a commitment to safe practices on the job.
