Show answer & explanationAnswer & explanation
Correct answer: C. To indicate the outer edge of the roadway that should not be crossed.
A solid white line on the right edge of the pavement is known as an edge line or fog line. Its primary purpose is to clearly define the outer boundary of the drivable portion of the road, separating it from the shoulder or roadside.
Why the other options are wrong
- A. No-passing zones are indicated by solid yellow lines.
- B. Bicycle lanes are typically marked with a solid white line and bicycle symbols.
- D. Broken white lines or solid white lines between lanes separate traffic in the same direction, but not the edge.
