In Texas you are required to present your CCL along with your drivers license. If they want to know if your are carrying they will ask you. Some do, and some don't. I have not received any tickets, except for warning tickets, but I have been pulled over, or presented license after an acccident when I was rearended. Each time a presented my CCL, and the officer, both local and highway patrol, very nicly thanked me for presenting the CCL. Of course they knew I had it because it is linked to your DL. A couple of times the officer and I actually got into a discussion of what our favorite pistols are. In Texas at least, the last person I want to shuck and jive or give a hard time to is a Texas Highway Patrolman. They are very courteous and professional, up to a point. Maybe I've been lucky, but I have never ran into a Texas LEO that was anti-gun or anti-CCL holders.
