text: You didn't mention your state and I believe it varies.  I'm going to assume since you said 'Freeway' and not 'highway' that you are closer to the west than the east, so the speed limit was probably 65, maybe even 70 as I know there are places in CA and NV that have a 70mph limit.  \n\nSo, you are 10 maybe 15 miles over the speed limit on a highway, you also didn't mention how the officer got your speed, again, I'm going to assume it was vascar or something similar.  They are pretty accurate and I wouldn't use that as the crux of my case if I were you.   \n\nThe thing in your favor is that the cop has to show up for his side to be heard so if the cop is busy, is on call, is sick or forgets, you walk.   Again you didn't mention your state but my money is on a fine and no points.  Show up on time, be respectful of the process, stay calm and answer the questions, treat this like a business matter, it will make you look more responsible, not like some 17 year old kid who drives too fast. \n\nGood luck.
