My question involves criminal law for the state of: Pa

I had a "roadrage" (for lack of a better word) incident with another driver and as soon as i had the opportunity i got into another lane and took off up the road passing him, aparently an officer noticed this and initiated a traffic stop. I was going very fast (about 90ish) and didnt notice the officer immediately. When i seen him waaay back there I figured he was coming for me but i wasnt sure, i slowed down and when he got behind me i pulled over. From the time i started driving fast to the site of the stop is 1.4 miles (about 45 seconds or so at that speed). I have a valid everything, no wants or warrants, i had no drugs weapons or anything else illegal. I am a contributing member of society, i am the head of a household with alot to loose and i would never run from the police.

My question is: Do i have a chance a beating this? If not, am i going to go to jail?

Thank You
