When my driver's license last expired, they gave me the option of renew over the telephone, and sent me a sticker to place on the back to extend the expiration date. In other words, the front has expired, but the back sticker corrects the problem. Should I go get another one before we cruise to avoid any potention problems, or will this be okay? I guess they could even call if necessary to verify its validity, but on a Saturday, who knows?
