Failure to maintain lane ticket?

last night me and my friends decided to go to walmart because there was nothing to do. i stopped and got gas and ended up running into my freind billy. he was driving a 2000 crown victoria that he was driving because he works for a dealership. billy said we would go to walmart so i followed him. billy was driving like a maniac, doing burnouts, donuts, excessive speeding etc.l when we got to the walmrt parking lot he was continuing to to burnouts rev his engine etc. i never did any speeding or burnouts. when we left we went down a road he was swerving all over the place so i decided to do just a small swerve. nothing serious. i was in complete control my tires probably went 4 feet over the line. the road has no houses in the area and you could clearly see oncoming traffic in front of you. suddenly a police car came up behing me and both me and billy pulled over. i got a failure to maintain lane ticket for 127 dollars. im a little frustrated bacause the officer felt billys tires, felt they were very warm and worn and knew he has a driving record but he got the same dollar amount ticket as i did. all i did was just a small swerve and have to pay 127 dollars. will this make my insurance go up. also he was driving a dealer plated car how did he not get in trouble for that. should i plead not guilty or just pay the fine. i did not endanger anyones life. i wasnt drinking, all i did was just swerve once. im just a little frustrated because i dont have any money right now and this is all i need. if i could even just get it reduced that would be awesome
