It depends on what you mean. If you have a permit to carry a gun, you can carry in Tennessee (TN recognizes permits from any state). If you are talking about transporting the gun, you can transport a gun basically anywhere in the U.S. without a permit as long as the gun is unloaded and not accessible.
It depends on what you mean. If you mean, can you have a gun in your car, the answer is, it depends. Some states, such as Mississippi, allow a person to carry a gun in the car even if the person doesn't have a permit, because the car is considered an extension of your home. Other states, such as Tennessee, allow car carry only if you have a valid handgun carry permit. Federal law allows you to transport an unloaded firearm in your car while travelling if the gun is unloaded and not accessible to you, so even if you don't have a permit, you can transport a firearm from one place to another, even if you don't have a permit, as long as you can legally possess the gun.
If you have a valid handgun permit from any U.S. state, you can carry the gun loaded and have it anywhere in the vehicle. If you do not have a valid carry permit, you must abide by federal transport law, which basically says the gun must be unloaded and not accessible. The best choice is unloaded and in the trunk with the ammo in a separate container.
