No Center Line

The roadway ahead has no painted center line dividing opposing traffic.

Posted on rural and low-volume two-way roads where the center stripe is absent, this warning tells drivers that the lane separation will be unmarked. Stay well to the right, anticipate oncoming traffic close to your path, and reduce speed on curves and crests where sight distance is limited.
