You were tailgating and the guy in front of you gave you a brake job? 'Way to go, Sherlock.
You probably won't get any days, but be prepared anyway. Tell the folks at work you're going to help care for your sister who came down with acute appendicitis and had to have emergency surgery.
The judge will ask you to plead. If you just plead guilty, the judge will ask you if you have anything to say. This is your big chance to get the judge to lighten up a little. Bring up the fact that you've been driving 80 years without a ticket or accident, that you screwed up and that you're terminally sorry for all the crap you dumped on everyone. You don't have to be sorry, but you have to say you are. See? Then start pleading poverty. Your sister, she's an invalid and you contribute to her care. Your folks are old, Dad's got arthritis, Mom's getting senile and it looks like they may have to move in with you next year. Then there's your blood sucking mother-in-law... okay, maybe not the mother-in-law.
So the judge will eventually tell you to put a sock in it and then he'll tell you about the fine and costs. If you can't pay you'll get sent to the slammer, but if you can then you pay and leave. The judge may also lecture, like he did with a friend of mine we'll call Wise Guy.
Wise Guy was busted for drunk and disorderly, raising hell and resisting arrest. They dropped the last two if he'd plead out to the D&D. So WG gets up in front of the judge, who gives him a fine and costs. The judge asks can he pay, and Wise Guy says he can but it'll cut into his beer money for the week. That will leave Wise Guy drinking vodka, which is how he got into this mess in the first place. Wise Guy can't drink vodka safely; only beer. Vodka makes him cut up and do stupid stuff and get busted, but it's better than tequila. Tequila makes him want to fight people.
So the judge commences to lecture. Blah blah blah, civic duty, bah-ba-bah, disgrace to the community, blah blah blah, your mother would not be proud of you, blah blah blah, unlawful hooligan with no respect for law and order. And on and on. Finally the judge winds down, giving Wise Guy the chance to run his mouth.
Jesus Christ, who pissed in your Wheaties this morning?
