Warning, Construction & Information SignsStandalone practice
A yellow diamond shows a black cow silhouette and identifies open range. What should you expect?
Correct answer: Livestock may be on or near the road
Why
The sign warns that livestock can be on or near the road. Reduce speed, watch for more animals and be ready to stop. Idaho also gives livestock under controlled movement over a road the right-of-way; the presence of fences does not guarantee that animals are absent.
