-Was driving under the posted speed limit in the left lane (which is an issue alone by itself)
I think I'm going to have to spell this out even more precisely.
Previously, I have already demonstrated that his driving below the speed limit was required by law. It is the legal requirment upon every driver. Perhaps he was driving slowly enough to have been impeding traffic, but that would be a judgment call on the part of a police officer—not one that can be satisfactorily made by watching a video on Facebook.
Moving on to the other half of your argument, then, I have bolded the pertinent phrases below in order to show that his being in the left lane has no legal bearing on the matter whatsoever.
Roadway.
That portion of a highway improved, designed or ordinarily used for vehicular travel, exclusive of the berm or shoulder. In the event a highway includes two or more separate roadways the term "roadway" as used herein shall refer to any such roadway separately but not to all such roadways collectively.
Laned roadway.
A roadway which is divided into two or more clearly marked lanes for vehicular traffic.
Highway.
The entire width between the boundary lines of every way publicly maintained when any part thereof is open to the use of the public for purposes of vehicular travel or located on public school property.
Controlled Access Highway.
Every highway, street or roadway in respect to which owners or occupants of abutting lands and other persons have no legal right of access to or from the same except at such points only and in such manner as may be determined by the public authority having jurisdiction over such highway, street or roadway.
Freeway.
A highway or street especially designed for through traffic and to, from, or over which owners of or persons having an interest in abutting land or other persons have no right or easement or only a limited right or easement of access, crossing, light, air, or view by reason of the fact that the property abuts upon the highway or street or for any other reason.
Traffic.
Pedestrians, ridden or herded animals, vehicles, streetcars and other conveyances either singly or together while using any highway for purposes of travel.
Drive on right side of roadway - exceptions.
(b) Upon a 2 lane roadway, providing for 2-way movement of traffic, a vehicle shall be driven in the right-hand lane available for traffic, or as close as practicable to the right hand curb or edge of the roadway, except when overtaking and passing another vehicle proceeding in the same direction or when preparing for a left turn at an intersection or into a private road or driveway.
(c) Upon any roadway having 4 or more lanes for moving traffic and providing for 2-way movement of traffic, no vehicle shall be driven to the left of the center line of the roadway, except when authorized by official traffic-control devices designating certain lanes to the left side of the center of the roadway for use by traffic not otherwise permitted to use such lanes, or except as permitted under Subsection (a) 2. However, this Subsection shall not be construed as prohibiting the crossing of the center line in making a left turn into or from an alley, private road or driveway.
(d) Upon an Interstate highway or fully access controlled freeway, a vehicle may not be driven in the left lane, except when overtaking and passing another vehicle.
So here's the evaluation:
5/11-701(b) specifically applies on any "2 lane roadway".
By definition, a "roadway" is the entire width from edge line to edge line, not counting any shoulder(s).
By definition, it is a "laned roadway" if it has clearly marked lanes for vehicular traffic.
The definition of "traffic" is not restricted to any one direction of movement, but refers in general to those conveyances using the roadway for travel.
Between edge line and edge line (i.e., within the roadway), the road you were on in that video
does provide for the two-way movement of vehicular traffic. However, it has
more than two lanes clearly marked for said traffic. Therefore, 5/11-701(b)
does not apply on that road.
Between edge line and edge line (i.e., within the roadway), the road you were on in that video has
four or more lanes clearly marked for traffic. Therefore, 5/11-701(c)
does apply on that road. The requirement set forth therein is that no vehicle may be driven to the left of the center line of the roadway. Remember the definition of "roadway"? It means the entire width from edge line to edge line. This law prohibits drivers from driving on the
wrong side of a multi-lane road. It
does not prohibit driving in any particular lane on the
correct side of the road.
The road you were on in that video allows ample "legal right of access" and "crossing" at various and sundry points along its length. I could clearly see driveways, intersections, and the like. Therefore, 625 ILCS 5/11-701(d)
does not apply on that road.
