What type of lighting is used to alert boat traffic to the location of piers on large rivers?

• A. Navigation lights
• B. Highway lighting
• C. Guide signs
• D. Street lighting

Answer: (A)

Navigation lighting is used to alert boat traffic to the location of piers on large rivers. These lights are specifically designed for mariners, marking hazards and helping vessels judge distance and safe paths at night or in poor visibility. On a pier, warning or obstruction lights outline the structure so boats won’t collide with it. This is different from land-based lighting like highway or street lighting, which are meant for drivers and pedestrians and aren’t intended to guide boats. Guide signs serve land traffic information and don’t provide the navigational cues mariners rely on. So, the lighting that alerts boat traffic to piers is navigation lights.
