Giải thích
On a divided or one-way roadway the triangles go at roughly 10, 100, and 200 feet behind the vehicle facing approaching traffic, and they must be placed within 10 minutes. Bunching them at the vehicle, using only one, or the 50 and 500 foot spacing does not give approaching drivers proper warning.
