Headlight dimming restrictions are found in which USOR section?

• A. USOR 408
• B. USOR 412
• C. USOR 410
• D. USOR 502

Answer: (B)

Headlight usage is governed by rules that tell crews when to dim the locomotive lights to avoid glare that could blind opposing trains, pedestrians, or other crews. The section that covers these headlight dimming restrictions is USOR 412. It lays out exactly when dimming is required or allowed, tying into safety practices for night and low-visibility operations. The other sections focus on different aspects of operations, such as signaling, train movements, or yard switching, so they don’t specifically address headlight dimming. That’s why USOR 412 is the correct reference.
