The law in every state, whose bicycle law I have read, is functionally similar. Bicyclists should stay as far right as practicable. Most laws go on to qualify "practicable" In doing so cyclists are given broad discretionary latitude. One of the reasons a cyclist can deviate from far right is for reasons of safety. Another is sub-standard (not wide enough for a cyclist and motorist to safely share) lane width. That describes a LOT of our roads.
Bicyclists who relegate themselves to hugging the right make themselves less visible. What's the number one excuse offered when a motorist hits a cyclist? "I didn't see them." Hugging the right invites squeeze passes and increases the likelihood of a sideswipe crash.
This is a very good quick and easy safety guide for cyclists. https://bicyclesafe.com/ A mitigating measure in nearly every scenario is to move further out into the lane.
