The back of my license shows the CCW as an additional endorsement. So to read it off it includes Hunter Safety Certificate, Carry Permit, Double or Triple Trailers, Airbrakes, and Tankers. I have not pursued the legalities but still carry my Permit to Carry.
The license does not include an expiration date, which no doubt could be ascertained by an officer who has my DL in hand. Which brings to light another interesting detail. Whether I tell the officer or not he will know I have a permit as soon as he sees the card. I'm okay with that, were I in his shoes I suppose that is another bit of background I wouldn't mind having between initial contact and calling in on the radio.
