You must stop on the shoulder near the top of a hill where drivers behind cannot see far. How does that change triangle placement?
- A.Place all triangles closer together for neatness
- B.Place the farthest triangle farther back, between about 100 and 500 feet, so it is visible before drivers reach the crest
- C.Skip the triangles because the hill hides the truck
- D.Place the triangles in front of the truck only
Correct answer
B. Place the farthest triangle farther back, between about 100 and 500 feet, so it is visible before drivers reach the crest
Why
Warning devices only work if drivers can see them in time to slow and move over. Extending the rear device to where the sight line opens turns a blind surprise into a warned approach.
