Most of these posts get a lot of hate. You were driving illegally and without a seatbelt. Since you've been driving for seven years, you know better.

You can try to explain your situation in court and hope for a merciful judge, but with all that I wouldn't expect much leniency. Just don't drive it again until it's legal. And put your seatbelt on. Hopefully you can get your fines reduced to something you can pay.
