I got pulled over for going 76 in a 55 (just before the 28 exit off I-66 west). I had to go to court for that crap, and it was a 6-point violation (reckless driving).

Last time I looked up the laws, there was nothing beyond reckless driving for going 20 miles over, but it's a misdemeanor which I believe means that the judge can give you jail time if he feels like it.
