I was in the left lane of a 4 lane highway in Illinois as I entered a work zone. I slowed down. However, the lane I was in was shortly ending. No one in the right lane was letting me get over, so when I saw a gap a few cars ahead, I sped up to make it in before the lane ended and thus avoid a car crash. I was then pulled over for doing 69mph in a 55mph work zone. My license is being held in bond pending a court date. What I want to know is is this situation justifiable? Should I plead not guilty? And also, what kind of fines am I looking at? My thanks for any advice.
