Difficulty: MediumPavement Markings and Lane Lines

You are driving in the right lane of a multi-lane road approaching an intersection and observe that the broken white lines separating your lane from the adjacent lane have transitioned into a single solid white line. Which of the following best describes the rules for crossing this pavement marking?

  1. Crossing a single solid white line is discouraged, and drivers should stay in their lane unless special hazards require a lane change.Answer
  2. B
    Crossing a single solid white line carries the exact same statutory prohibition as crossing a double solid yellow line.
  3. C
    Passing across a single solid white line is legally permitted only if the entire maneuver is completed within 100 feet of the intersection.
  4. D
    Crossing a single solid white line is allowed only when passing a vehicle traveling below the posted minimum speed limit.

Answer

Crossing a single solid white line is discouraged, and drivers should stay in their lane unless special hazards require a lane change.
The correct answer states that crossing a single solid white line is discouraged and drivers should stay in their lane unless avoiding a hazard. Single solid white lines are used between lanes moving in the same direction to indicate that lane changes are discouraged, particularly in areas near intersections or traffic chokepoints where changing lanes creates additional conflict points.

Step-by-Step Solution

1
Identify the direction of travel indicated by white pavement markings.
White lines separate lanes of traffic traveling in the same direction.
Yellow lines separate opposing traffic, whereas white lines designate same-direction lanes.
2
Analyze the meaning of a single solid line pattern versus broken or double solid lines.
A single solid line signals that changing lanes requires extra caution and is discouraged, whereas double solid white lines prohibit changing lanes completely.
Solid lines indicate restricted maneuverability, but single solid white lines serve as advisory restrictions encouraging drivers to maintain their lanes.
3
Evaluate the intersection context and legal passing prohibitions.
Passing near intersections is generally unsafe and prohibited within 100 feet, making lane maintenance critical.
Lane changes directly before an intersection increase collision risks with turning or stopping vehicles.
