Do I need to show up at the location specified to clear it? Will I get more information about what to do in the mail? Is there a fine?
You'll probably have to pay a processing fee too. If I remember correctly I paid about $25 a few years ago. Make sure you get it cleared before the deadline, otherwise you'll get a fine.
Holy shit why do people post on blind for this stuff. Google it kid
Fix-it tickets are more of a recommendation than a requirement. You can safely drop it in the trash and not worry about it.
Fix it and go to the nearest police station and get it signed
