While waiting for my CHL I mused about carrying to and from work, since I own my office.The only requirement is you cannot still have it on your person when you step out of the car.
Seems like you could tuck your popgun away from view (in a safe holster, please) and go to and from your car, and drive most roads without a CHL.Sec. 46.02. UNLAWFUL CARRYING WEAPONS. (a) A person commits an offense if the person intentionally, knowingly, or recklessly carries on or about his or her person a handgun, illegal knife, or club if the person is not:
(1) on the person's own premises or premises under the person's control; or
(2) inside of or directly en route to a motor vehicle or watercraft that is owned by the person or under the person's control.
In my fogged understanding, I don't think you can drive through school zones with a pistol unless you have a CHL.
Welcome to Texas, by the way, sorry your current Ohio CHL isn't recognized.
