International Regulations for Preventing Collisions at Sea
The International Regulations for Preventing Collisions at Sea 1972, also known as Collision Regulations (COLREG), are published by the International Maritime Organization (IMO) and set out, among other things, the "rules of the road" or navigation rules to be followed by ships and other vessels at sea to prevent collisions between two or more vessels. COLREG can also refer to the specific political line that divides inland waterways, which are subject to their own navigation rules, and coastal waterways which are subject to international navigation rules. They are derived from a multilateral treaty called the Convention on the International Regulations for Preventing Collisions at Sea, also known as Collision Regulations of 1960.
Although rules for navigating vessels inland may differ, the international rules specify that they should be as closely in line with the international rules as possible. In most of continental Europe, the Code Européen des Voies de la Navigation Intérieure (CEVNI, or the European Code for Navigation on Inland Waters) apply. In the United States, the rules for vessels navigating inland are published alongside the international rules.
As of 2022, there are 41 Rules and four annexes in COLREGs Rules in force.
Rule 1 - Application. This rule states that the COLREGs should be complied with by all vessels on the "high seas".
Rule 2 – Responsibility. This rule allows Master mariners and other persons in charge of vessels to depart from the rules to "avoid immediate danger", provided there are special circumstances for doing so. The rule also effectively requires all navigators to exercise good seamanship in applying the rules.
Rule 3 – General Definitions. This rule sets out key definitions that apply to terms in the rest of the rules, including definitions for 'power-driven vessels', 'sailing vessels' and other terms such as 'not under command' and 'vessel restricted in her ability to manoeuvre.
Rule 4 – Application. This rule states that the rules in this section apply to all vessels in any condition of visibility.
Rule 5 – Look-out. This rule concerns the keeping of a proper lookout to sea. It involves keeping the lookout by all available means, including audible means, visual means and by the use of marine radar.
