COLREG decision quiz

Eighteen scenario-based questions drawn from the International Regulations for Preventing Collisions at Sea 1972 (COLREGs). Each question describes a real encounter — aspect, lights or shapes visible, sea conditions — and asks which Rule applies and what action you must take. Covers: Rule 8 (action to avoid collision), Rule 9 (narrow channels), Rule 10 (TSS), Rule 13 (overtaking), Rule 14 (head-on), Rule 15 (crossing), Rules 16–17 (give-way and stand-on), Rule 18 (responsibilities between vessels), Rule 19 (restricted visibility), and Rule 34–35 (sound signals). Use for STCW officer of the watch preparation or watchkeeping refresher.
