All small passenger vessels operating on lakes, bays, sounds, or river routes on runs of more than 30 minutes are required to carry __________. (small passenger vessel regulations)

Correct Answer: Option B — 3 red hand flare distress signals and 3 orange smoke hand distress signals

46 CFR 180.68 dictates the carriage requirements for visual distress signals based on the vessel's route and duration of operation. For lakes, bays, sounds, or river routes exceeding 30 minutes, the regulation specifically mandates three red hand flares and three orange smoke signals for emergency signaling.
