A few years ago, Tennessee allowed a person to carry in an establishment, that is not posted, that serves alcohol as long as said person does not engage in same. Not even a sip.
Also, Tennessee allows anyone who can legally purchase a gun to keep one in his or her vehicle fully loaded. That person can not remove the gun from the vehicle without a carry permit. It is a form of extension of the castle doctrine. This came about to make it legal for another,
non- permitted person, to drive a permitted person, who purposely left his or her gun in the vehicle, if the permitted person, did in fact decide to indulge in an alcoholic beverage and may be over the limit.
The firearm in the vehicle was considered still in possession of the permit holder when returning to the vehicle, thus being illegal for the person who had the beverage (the permit holder) to be in possession. Past law made it illegal for a designated driver, non-permit holder, to have a firearm in the vehicle, now that the permit holder was disqualified due to indulgence. As a result, both of them were breaking the former law while trying to be good and most of the time without even knowing it. As we know, ignorance of the law is no excuse
.
Tennessee saw the failure of this and changed the law accordingly. Now allowing a non-permit person, legally able to buy a gun, the right to keep it in the vehicle and in this case, drive the permitted person and be within the limits of the law. We still haven't gotten permitless carry.
