- CYou must not cross this line to change lanes.
- DYou are permitted to change lanes if it is safe to do so.
Show answer & explanationAnswer & explanation
Correct answer: C. You must not cross this line to change lanes.
A solid white line on the pavement indicates that lane changes are prohibited. It is used to delineate the edge of a roadway, separate lanes moving in the same direction where lane changes are dangerous, or designate special purpose lanes.
Why the other options are wrong
- A. Solid white lines are prohibitive, not merely discouraging.
- B. Exit ramps often have solid white lines, but the primary meaning is no crossing, not just an exit indicator.
- D. A dashed white line permits lane changes.
Solid White Line (Pavement Marking)
A pavement marking that indicates lane changes are prohibited or highly discouraged, separating traffic flowing in the same direction.
- Separates lanes of traffic going the same direction.
- Indicates that crossing the line is not permitted.
- Often used near intersections, on bridges, or for special-use lanes.
Memory trick: Solid white, stay tight, no crossing, keep it right.
