International Regulations for Preventing Collisions at Sea

Also known as: COLREGS, International Rules of the Road

Quick Summary

The International Regulations for Preventing Collisions at Sea, often called COLREGs, are internationally agreed-upon traffic rules for ocean waters. These rules, based on British regulations from 1862 and refined through international conferences, specify how ships must navigate in relation to each other. They cover crucial aspects like the color and arrangement of lights, the size and shape of daymarks, sound signals, and the appropriate actions to take when vessels approach each other. The regulations vary for different types of vessels, including power-driven and sailing ships, with some exceptions for smaller craft and naval vessels. Adherence to these rules is essential for preventing collisions and ensuring safety at sea.123
