    I didn't realize that "over the counter" delivery of drivers licenses was not the normal method. When I get a new driver's license at the DMV, I go to a self serve kiosk, have my picture taken, then walk over to a room and my license is already printed by the time I get there. They have 3 massive card printers (imagine a laser printer, but 6 ft/182.88 cm long). It event prints a pseudo-hologram.

    I have to surrender my old license to the person in the room. How does that work if your license is mailed to you? Do you get to keep the old one?

      How it works in my state: For in person renewals/changes, they punch VOID into your old license, give it back to you, and give you a temporary license printout. Then your new license is mailed a couple weeks later.

      For remote renewals/replacements, they just give you a temporary license to print out and then mail you a new one. The old license never gets physically cancelled.
