House Bill 4585 amends 625 ILCS 5/11-204.1 by increasing a first offense for Aggravated Fleeing or Attempting to Elude a Peace Officer from a Class 4 felony to a Class 2 felony and a second or subsequent offense from a Class 3 felony to a Class 1 felony. This would increase the sentence range and mandatory supervised release period for those sentenced.
