USCG Exam Practice · Rule 28 — Constrained by Draft (lights)
A vessel not under command that is making way through the water at night must exhibit which combination of lights?
- ATwo all-round red lights in a vertical line, sidelights, and a sternlight✓ correct
- BThree all-round lights (red-white-red) in a vertical line, sidelights, and a sternlight
- CTwo all-round red lights in a vertical line and a masthead light
- DTwo all-round red lights in a vertical line only; no other lights are required
Why A is correct
33 CFR §83.27(a)(i) requires two all-round red lights in a vertical line, and §83.27(a)(iii) adds sidelights and a sternlight when the vessel is making way. The red-white-red pattern belongs to a vessel restricted in her ability to maneuver, not one not under command.
