You are correct about carrying in the state of Texas in your vehicle loaded without a chl. The new castle law allows it. There are requirements that must be met although.......You must be driving a vehicle that is registered to you or your spouse, and you must be able to purchase a handgun legally with no prior disqualifying circumstances, ie: criminal activity or other "stuff".. There is still a fine line in carrying concealed though without a license....know your rights,,,,,,,,.........
