One law overrides another when there is a conflict. For instance, a slower driver is generally required to stay right, but the left turn law specfically requires them to merge left. A car driver must generally not travel far below the normal speed of traffic, but must do so when slowing to avoid a bicyclist ahead on the roadway, or to prepare to execute a turn or other maneuver safely. Hand signals must be made from the left arm, except where a cyclist is explicitly allowed to use the right hand.
There is no conflict between the FRAP law, bicycle-specific or otherwise, and the general turn-out law applicable to all drivers whose speed ends up limited for one reason or another. The cyclist, or tractor driver, or boat-hauler (I pull a boat behind my Element on occasion) must stay FRAP when traveling slower than other traffic, but this does not prevent them from turning out when traffic backs up on a 2-lane, nor does turning out on occasion preclude them from operating FRAP while on the roadway.
