What is required to legally transport a firearm through Louisiana?

Transporting a firearm through Louisiana requires the firearm to be unloaded and in a locked container. Option A is incorrect because there is no special transportation permit required. Option C is incorrect because Louisiana does not have a specific gun owner's license. Option D is incorrect because firearms do not need to be registered with the state in Louisiana. Therefore, the correct answer is B. This ensures the firearm is safely stored and not readily accessible while being transported. Additionally, it follows federal and state guidelines for the transportation of firearms.
