About this exam
The U.S. Coast Guard Merchant Mariner Credential Rules of the Road—International Examination assesses knowledge of the International Regulations for Preventing Collisions at Sea, commonly called the International Rules or COLREGS. It is taken by applicants whose requested credential or endorsement requires this examination; it is not a general college or employment entrance test. The credential application process also has separate requirements, which may include sea service, medical documentation, and other qualifications. Check current U.S. Coast Guard guidance for the requirements that apply to your application.
Expect to study how the International Rules apply, key definitions and vessel categories, and the responsibilities of vessels underway or in restricted circumstances. Important areas include keeping a proper lookout, proceeding at a safe speed, assessing collision risk, taking effective avoiding action, and navigating narrow channels and fairways. Exam modules and testing arrangements can depend on the credential sought and the applicant’s route. Prepare by learning the rule language and applying it to navigation situations, rather than relying only on memorized phrases; online multiple-choice practice can help you check understanding.
How to prepare for the International Rules of the Road exam
- Review the current International Rules rule by rule, focusing on scope, definitions, vessel categories, lookout, safe speed, risk of collision, and collision-avoidance action.
- Work through scenario-based questions under timed conditions; after each set, explain why the applicable rule fits and why other actions would be unsafe or incorrect.
- Use current U.S. Coast Guard application and examination guidance, along with authoritative versions of the Navigation Rules, to confirm the required exam modules and the rules you are expected to know.
