Actually, speaking from SC, no matter what your LEO friends tell you they want, you are required to inform the LEO that you are armed during a traffic stop, if you are.
Friends change their minds and the law stay's the same.
FL is a "No duty to inform" state as far as CCW is concerned.
If they ask you if you have a firearm you must inform them you have a CCW permit and are legally armed. I would suggest that if they ask you a "Do you have anything I should be aware of" type question you should also inform them about having a permit and legally armed.
