Florida Practice Road Markings

A single broken white line separates lanes traveling in the same direction. What does it allow you to do?

A single broken white dashed line running lengthwise down a dark roadway.
  1. A.
    Treat it as the right edge of the roadway.
  2. B.
    Cross only to pass a slow-moving farm vehicle.
  3. C.
    Cross the line to change lanes when it is safe. Correct
  4. D.
    Drive across it only when a hazard forces you to.
The Why

The answer is "Cross the line to change lanes when it is safe."

Broken white lines separate lanes moving the same direction, and you may cross them to change lanes when it is safe. The hazard-only rule in D is the one printed one bullet down for a single SOLID white line; readers who blur the two white-line rules into one pick it here.

Why the others miss

The traps in the wrong answers

A. Treat it as the right edge of the roadway.

The right edge of the roadway is marked by a single solid white line, not a broken one. Confuses lane-separation markings with edge lines because both are painted white.

B. Cross only to pass a slow-moving farm vehicle.

The broken white line is not tied to any specific vehicle type; the manual states a general safe-to-cross rule. Borrows a rural-road habit that pins passing rules to slow farm equipment rather than to the line color and pattern.

D. Drive across it only when a hazard forces you to.

The hazard-only rule applies to single solid white lines, not to broken white lines. Applies the hazard-only limit from the single solid white line rule printed one bullet down because the reader recalls 'do not cross a white line' as one blanket habit rather than a rule that varies by pattern.
