During night traffic control, which signaling approach improves visibility?

• A. Use slow, large motions
• B. Use fast, small motions
• C. Only use verbal directions
• D. Ignore signals

Answer: (A)

Nighttime signaling works best when signals are easy to notice and follow from a distance. Slow, large motions create a clear, predictable cue that drivers can see even in low light and glare, making it easier to judge your intent and react appropriately. The larger arc and deliberate pace improve visibility and reduce misreading, helping cover the whole range of distances at which drivers may be watching. Verbal directions can be missed in noise or overruled by ambient conditions, while fast or tiny motions are easy to overlook or misinterpret. Ignoring signals is unsafe. So, slow, large motions are the most reliable way to improve visibility during night traffic control.
