COLREGs Lights and Marks

COLREGS Rules Огни и знаки

COLREGs lights and marks are an integral part of the International Regulations for Preventing Collisions at Sea (COLREGs-72) and play a key role in ensuring maritime safety.

The system of lights and marks is designed to indicate vessels in various visibility conditions, their maneuvers, and characteristics, helping to prevent collisions and ensure a clear understanding of the situation on the water.

These rules are mandatory for all vessels, including naval ships in peacetime, regardless of their size and purpose.

On this page, you will find a complete list of COLREGs lights and marks, as well as simulators that will help you test and reinforce your knowledge in a convenient “game-like” format.
