• Inland lock and dam safety zones on U.S. rivers • How the Coast Guard and Army Corps of Engineers warn boats away from dangerous current near dams • Differences between buoys, signs, and lights as regulatory markers

💭 Think About

• When you approach a lock or dam on a river at night, which of these methods would be most visible and clearly warn you to stay clear? • Think about which answer choice sounds like a standardized danger / restricted area warning, not just normal navigation aids. • Which options describe ordinary aids to navigation (like channel markers) versus special warnings of hazards or restricted areas?

✅ Before You Answer

• Identify which colors and types of aids are normally used for channel marking (lateral system: red/right-returning, green/port), not for restricted areas. • Consider which options mention explicit warning methods (such as ‘signs’ or ‘flashing red’), which are typically used to mark dangerous restricted areas. • Visualize a real lock & dam: what do you most often see posted or flashing near the dam face itself to keep small boats out?
