Back in '68 when I was 17 I got a ticket in Ohio on old route 40 for doing 105 in a 50. Back then the nighttime speed limit was 50 on the ol' 4-lane that was 70 in the daytime.
Good thing my $350 '62 Galaxie would only do 105.
I don't remember the ticket price but I remember with my Gas Station job wages it took a long time to build back my savings I had going for a Muscle Car.
I lost my license until I turned 18 and I paid big on insurance for a long time afterwards.
When I finally did get my Muscle Car my insurance monthly payments were more than my Car payments!
I'm sure things have changed a lot since then, but the principles of penalties are still bad, probably worse.
Good luck with it and if you can, contact a Lawyer and at least get advice on your options.
