How does a flashing light operate under the rules?

• A. Flashes at 60 times or more per minute
• B. Always remains steady
• C. Flashes at 120 times or more per minute
• D. Flashes at varying intervals

Answer: (C)

A flashing light, as defined by the International Regulations for Preventing Collisions at Sea (COLREGs), is characterized by its frequency. Specifically, a light that flashes at 120 times or more per minute serves a particular purpose in signaling to other vessels. This high-frequency flashing indicates specific states or situations, such as those of vessels engaged in certain operations or specific types of warning signals. While choices regarding a lower frequency of flashes or a steady light may also exist, they do not meet the definition of a flashing light as it pertains to the COLREGs. Signals that remain steady are used for different indications, such as maintaining visibility, but do not convey the same urgency or alerting function that a rapid flashing light does. Thus, the definition of a flashing light includes the requirement of it flashing at frequencies of 120 times or more per minute, which aligns with maritime safety and communication standards. This distinctive characteristic of a flashing light helps to quickly relay critical information to other vessels in the vicinity, enhancing navigational safety.
