COLREGs · Rule 24
Towing and Pushing
TL;DR
Different light arrangements for towing astern (length of tow drives masthead-light count), pushing ahead, towing alongside, and towing operations that severely restrict ability to deviate (NUC-style three-light vertical).
Why it shows up on the exam
Inland and international diverge significantly — Inland Western Rivers towing has its own light scheme.
