Who is Responsible For Clearing Our Roadways?

I see it all of the time: Something in the roadway like a tire, dead animal or a bunch of tree limbs. I swerve to miss it then wonder, who is going to get that out of the way so it doesn't cause a wreck. Sometimes I move it. Sometimes it is too much of a hazard for me or I am in a super huge hurry.

Should we call someone about debris in the middle of the road?
