Surplus German Military Road Hazard Signs We hate those lightweight hazard warning signs that break and blow over when a semi rolls by. This triangular road hazard sign from the German military is 17" long on each leg and stands on heavy olive drab steel legs that fold out to make a 17-1/2" x 16-3/4" footprint that isn't going anywhere. Weighs almost 5 pounds. Has been used for a few light hazards, but has years of danger ahead of it. Stores in a 18" long x 3-1/2" x 2-1/4" hard plastic case with German instructions you won't need.
