USCG Exam PracticeLeeway allowance in plotting
A vessel is navigating in a traffic separation scheme. When crossing a traffic lane, the vessel should cross on a heading that is:
- A. Parallel to the general direction of traffic flow
- ✓ As nearly as practicable at right angles to the general direction of traffic flowCorrect
- C. At as small an angle to the general direction of traffic flow as practicable
- D. At a 45-degree angle to the general direction of traffic flow
Why B is correct
33 CFR §83.10(c) states that a vessel obliged to cross a traffic lane shall do so on a heading as nearly as practicable at right angles to the general direction of traffic flow. Option C describes the requirement for joining or leaving a lane, not crossing one.
