Just got my first speeding ticket

Welp, I just got my first speeding ticket at 21. Ticket says I was going 67 in a 45 but I genuinely did not feel like I was going that fast, especially being that I was passing through a light. Being that I’m 21 and have never gotten any violations before, i was wondering how screwed I am in terms of insurance going up (I’m still on my moms policy).

Court date is next month and I am not looking forward to it😭
