yeah, got the same thing you did, 77 in a 45, the ticket was going to be $440 give or take a few...
you will loose your licence for 6 months, if it happens that bad again I think you loose it until your 21.
I however did not loose my licence, I was going to, I should have, was about to, but I knew a county prosecutor who got me an interview with the powers that be, and he ended up vouching for me, they reduced it to 23 over and gave me 24 hours of community service, and a Defenceive driving course and a $230 fine....I got lucky, don't want to do it again,
all I can say man is :
1) wear a Suit! this will definitely help
2) make sure you are clean shaven
3)remove any (visible) body rings or things of that nature
4) bring documentation of anything good you have done lately (Ie: grades, comm. service, ect...)
5) let the court know youre a good hard working kid who was in the wrong place at the wrong time...
6) and if you can afford it, get a lawyer...he'll know what to do.
oh and 7) try to be light on the gas for the next 2 or so years, (or get a good detector like me...
)
