You are driving on a multi-lane highway in Florida. You see a solid white line separating your lane from the lane to your left. What does this pavement marking indicate?

  1. ALane changes are discouraged but not prohibited.
  2. BThis line indicates an upcoming exit ramp.
  3. CYou must not cross this line to change lanes.
  4. DYou are permitted to change lanes if it is safe to do so.
Show answer & 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.
