although the thread has been beat to death, I'd like to add my 2 cents worth. Chevron: To be placed IN the apex of the turn, minimum of one; or as many as the trail design demands, if the chevron is used--it is ALWAYS preceded by the advance placement of the appropriate caution sign--the right angle turn, hair pin, or slow curve. The chevron is not to be placed in advance of the turn--it does not replace the arrow. The arrow--yellow/black 6x12, is to be place In advance of the turn on the right side of the trail--pointing left or right. I would like to see WI adopt the MI size arrow(12x16). Caution/caution ahead--a very misused sign in WI--if used, the sign should be followed by the appropriate caution sign--bridge, dip, etc. Although the signing handbook is only a few pages, most don't bother to read it. the reason for the book is to establish uniformity in signing through out the state.
