What change does a divided-highway-begins warning announce?
- Two-way traffic will be divided by a center strip
- All traffic will share one undivided lane
- The roadway is ending at a railroad track
- U-turns are required around the next island
Answer: Two-way traffic will be divided by a center strip. The divided-highway warning means the two-way roadway is approaching a center strip that separates traffic. Follow your side of the roadway and keep the median or barrier to the proper side as directed. This is not an instruction to share one lane, stop at railroad tracks, or make a U-turn. Reduce speed if the change in alignment is difficult to see, and use lane markings and arrows to confirm your path around the center strip.
