   (A)   Rules To Govern: The following rules shall govern the overtaking and passing of vehicles proceeding in the same direction, subject to these limitations, exceptions and special rules hereinafter stated:
      1.   The driver of a vehicle overtaking another vehicle proceeding in the same direction shall pass to the left thereof at a safe distance and shall not again drive to the right side of the roadway until safely clear of the overtaken vehicle.
      2.   Except when overtaking and passing on the right is permitted, the driver of an overtaken vehicle shall give way to the right in favor of the overtaking vehicle on audible signal and shall not increase the speed of his vehicle until completely passed by the overtaking vehicle.
   (B)   Overtaking Vehicles On The Right:
      1.   The driver of a vehicle may overtake and pass upon the right of another vehicle which is making or about to make a left turn.
      2.   The driver of a vehicle may overtake and allowing sufficient clearance, pass another vehicle proceeding in the same direction either upon the left or upon the right on a roadway with unobstructed pavement of sufficient width for four (4) or more lines of moving traffic when such movement can be made in safety. No person shall drive off the pavement or upon the shoulder of the roadway in overtaking or passing on the right.
      3.   The driver of a vehicle may overtake and pass another vehicle upon the right on a one-way street or on any street on which traffic is restricted to one direction of movement where the roadway is free from obstruction and of sufficient width for two (2) or more lanes of moving vehicles.
   (C)   Limitations On Overtaking On The Left:
      1.   No vehicle shall be driven to the left side of center of the roadway in overtaking and passing another vehicle proceeding in the same direction unless such left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be completely made without interfering with the safe operation of any vehicle approaching from the opposite direction or any vehicle overtaken.
In every event the overtaking vehicle must return to the right hand side of the roadway before coming within one hundred feet (100') of any vehicle approaching from the opposite direction.
      2.   No vehicle shall, in overtaking and passing another vehicle or at any other time, be driven to the left side of the roadway under the following conditions:
         (a)   When approaching the crest of a grade or upon a curve in the highway where the driver's view is obstructed within sufficient distance as to create a hazard in the event another vehicle might approach from the opposite direction.
         (b)   When approaching within one hundred feet (100') of or traversing any intersection or railroad grade crossing.
         (c)   When official signs are in place directing that traffic keep to the right, or a distinctive line also so directs traffic as declared in the sign manual adopted by the Illinois state department of public works and buildings.
         (d)   The limitations in subsections (C)2(a) and (C)2(b) of this section shall not apply upon a one-way street, or upon a street with unobstructed pavement of sufficient width for two (2) or more lanes of moving traffic in each direction when such movement can be made with safety.
