In Illinois law 625 ILCS 5/11-709 subsection? b there is text that states the following:
(b) Upon a roadway which is divided into 3 lanes and provides for two-way movement of traffic, a vehicle shall not be driven in the center lane except when overtaking and passing another vehicle traveling in the same direction when such center lane is clear of traffic within a safe distance, or in preparation for making a left turn or where such center lane is at the time allocated exclusively to traffic moving in the same direction that the vehicle is proceeding and such allocation is designated by official traffic control devices. http://www.ilga.gov/legislation/ilcs/ilcs4.asp?DocName=062500050HCh%2E+11&ActID=1815&ChapterID=49&SeqStart=111500000&SeqEnd=136400000
What I'm trying to determine is what type of roadway is being referred to when it's stated "3 lanes and provides for two-way movement of traffic". This initially sounds like a two-way left turn lane, but there is also text stating that:
a vehicle shall not be driven in the center lane except when overtaking and passing another vehicle traveling in the same direction when such center lane is clear of traffic within a safe distance
Which to me would mean 625 ILCS 5/11-709 subsection b mustn't be referring to a two-way left turn lane because using those to pass is strictly prohibited by 625 ILCS 5/11-801.b.2:
A vehicle shall not be driven in the lane except when preparing for or making a left turn from or into the roadway or when preparing for or making a U turn when otherwise permitted by law.
So what type of 3 lane two-way roadway is 625 ILCS 5/11-709.b talking about?
