Sign Placement for Roadside Stands

I recently read an article entitled, "Roadside Stands," by  Renee M. Lloyd, James R. Nelson, Daniel S. Tilley. Although the article was written in 1995, its contents are still useful for today's road side operations.

The table below provides measurements at appropriate distances to help insure easy reading of signs.
