Well, when I first got my Mississippi license back in '98, I gave them a correct weight. Then, I lost (actually misplaced) it two or so years later and when I got a replacement, had them up the weight 20 lbs, which was accurate at the time. I had to renew last year and just kept the weight where it was, which is decidedly NOT accurate!
Right now, the weights are about 55 lbs. off.
When I worked at K-Mart (for less than a month!) in college, I learned that most overweight people lie on their driver's license. The weight of choice is 125#.
Beverly, have you ever had a problem with people not believing that you are the person on your ID? Has anyone ever had that happen to them?
