A solid white line on the right edge of the highway slants in toward your left. This shows that:
- There is an intersection just ahead
- You are approaching a construction area
- You will be required to turn left just ahead
- The road will get narrower ✓
Answer: D. The road will get narrower
A solid white edge line that slants toward your left means the road will get narrower.
Why this is the answer
The manual explains that the solid line along the side marks the edge of the travel lane, where the shoulder starts. When that edge line angles toward the center, it signals less pavement ahead. So the slant is a warning about the road's width, not about an intersection, a work zone, or a required left turn. The correct choice is the one saying the road will get narrower.
Why the other answers are wrong
- A. There is an intersection just ahead — The passages describe stop lines and crosswalks at intersections, but they do not say that an inward-slanting edge line announces an intersection.
- B. You are approaching a construction area — Nothing in the passages connects an edge line angling in with a construction area.
- C. You will be required to turn left just ahead — The manual says arrows show which lanes to use for turns and edge lines mark the road's edge, so an inward slant does not mean a left turn is required.
Remember it
When the white edge line leans in, picture the shoulder closing in on the lane.
