USCG Exam PracticeRule 8 — Action to Avoid Collision

A vessel is required by the Inland Rules not to impede the passage of another vessel. Risk of collision subsequently develops between the two vessels. Which statement correctly describes the obligations of the vessel whose passage is not to be impeded?

  1. A. It is relieved of all obligations under Rules 4–19 because the other vessel must keep clear.
  2. It remains fully obliged to comply with Rules 4–19 when the two vessels are approaching so as to involve risk of collision.Correct
  3. C. It must immediately stop and take all way off until the other vessel passes.
  4. D. It may only take action after the other vessel has failed to comply with the non-impede obligation.

Why B is correct

33 CFR §83.08(f)(iii) states that a vessel the passage of which is not to be impeded remains fully obliged to comply with Rules 4–19 when the two vessels are approaching one another so as to involve risk of collision. The non-impede obligation does not suspend the privileged vessel's duties under the steering and sailing rules.
