Court Tomorrow

First time going to court. I rolled a stop sign in October and she also got me on a missing registration sticker. The car I was driving is my dads and he forgot to put the sticker on, smh. So I got 2 tickets. 1 for a stop sign and a missing registration sticker.

I gave the cop my paper registration but she denied it. Not sure fucking why but that’s frustrating. My town is definitely looking for people to slightly fuck up.

Am I going to court for the sole purpose of showing proof of registration and paying the stop sign fee? Do I plead guilty for rolling it, paying the fine, and going about my day?

Please help, preferably a real traffic defense attorney. Thanks
