it means you legally dont have to be 'defenseless' if you choose not to be...strap yer pistol on yer hip, or toss it on the seat, or dash or glove box and youre 'legal'...full statewide pre-emption from any local bs ordinances too...
that doesnt however, mean that there aint a rouge dumbass cop that might challenge ya...just not likely if ya act like ya got some sense...
