How do I remove this warrant for a minor ticket?

About a month ago I got a minor ticket for not having my parking permit thing hanging from the window. It was a 26 dollar ticket that I did not really pay attention to, well a month + a week passed and now I guess I have a warrant out for my arrest (that is what the paper I received in the mail says) can I still pay the ticket even though this time limit thing is up….(If this is a stupid question do not bother telling me, I am 18….)

P.S. Since I never got pulled over they just left the ticket on the windshield of the car and sent the letter saying there would be a warrant for my arrest to my MOTHER since it is her car…can I still pay the ticket? BTW, I do not need to be reminded how big of a moron I am, I get it. Help please.
