Their information is a little vague with a broad range in many states. Here in Maine (I have my street reference fines book here in front of me) the fines, regardless of prior history, are as follows
Speeding 1-9 over $119
10-14 over $137
15-19 over $189
20-24 over $215
25-29 over $263
All of the above are traffic infractions and do not involve going to court just paying or if you contest the ticket you have a motor vehicle bureau hearing kind of like court.
30mph or more over is Criminal Speed and involves going to court and a larger fine ($500 or more) and possibly jail time. You can and will likely be arrested on the spot for Criminal speed.
If the area in which you are speeding is a school zone or a construction zone then the fines get much larger, basically twice that of a normal ticket, speeding 25 over in a contruction zone is $516 (not quite double)
Not that many of you will be in Maine but I just was wondering where the report got its numbers there is no such thing a $25 ticket here.
