Roadway Position (see Section 316.2065, F.S.)

A bicyclist who is not traveling at the same speed of other traffic must ride in the lane marked
for bicycle use or, if no lane is marked for bicycle use, as close as practicable to the right-hand curb or edge of the roadway except in the following situations: when passing, making a left turn, to avoid road hazards, or when a lane is too narrow for a bicycle and a car to share safely.
A bicyclist operating on a one-way street with two or more traffic lanes may ride as close to the left-hand edge of the roadway as practicable.
Persons riding bicycles upon a roadway shall not ride more than two abreast except on paths or parts of roadways set aside for the exclusive use of bicycles. Persons riding two abreast shall not impede traffic when traveling at less than the normal speed of traffic at the time and place and under the conditions existing, and shall ride within a single lane.
This was copied from the Gainesville Cycleing Club’s website.

It doesn't say who gets to determine when it's safe or not.
