You are actually talking about two separate issues, even though most of the time they get confused as the same thing. The first is the criminal aspect of the violation. Its a misdemeanor offense that carries a fine which is set by the jurisdiction. The second is an administrative license suspension based on a point system the department of driver services has put into place. The big key difference is that the points schedule is set around the offense and its final disposition, not what the original charge was.
For instance, you could have been charged with DUI, but if you pled down to reckless driving, then you might see a difference in points on your license. The DDS has a webpage which lists all the ways your license may be suspended administratively
here. 15 over the speed limit is only 2 points and doesn't bring her anywhere near a license suspension as long as she doesn't have existing points.
A super speeder fine is another administrative fine thats "tacked on" independently of any court appointed punishment (fees/fines/probation etc).
At the end of the day the criminal charge is important because thats what starts all the other administrative add ons. Thats why most people here are recommending that your daughter (or you) find a way to get that charge reduced from a speeding in excess of the speed limit (40-6-181) charge to a general speeding (40-6-180) charge because it doesn't give you all the extras that the Department of Drivers Services loves to hit people with.
I know that was a little lengthly, but its important to understand the criminal and administrative penalties and how they effect you because that will help you determine if your citation is worth fighting. A simple conversation with most prosecutors can usually get things worked out in your favor without the hassle of a lawyer and a bunch of wasted court time. I dont think 85 in a 70 in and of itself is reckless but it is important for teenagers to understand how seriously driving should be taken so this may be a good opportunity for your daughter to learn that. Obviously you know better than any of us if this is a pattern or just a mistake so please dont think i am trying to tell you how to parent your children...I would not do that.
