A single dashed white line on a multilane road means:
Answers
Lanes are moving in opposite directions.
Passing is permitted into a lane directly next to the dashed white line.
Passing is prohibited.
None of these.
The Correct Answer and Explanation is :
The correct answer is: Passing is permitted into a lane directly next to the dashed white line.
Explanation:
In traffic lane markings, dashed lines—whether white or yellow—indicate that vehicles may cross the line under certain conditions. Specifically, a dashed white line separates lanes that are moving in the same direction, typically in a multilane road. When you encounter a dashed white line, it generally means:
- Passing is allowed: You are permitted to move from one lane to another if it is safe to do so. This can involve merging into the lane directly next to you, as long as no obstacles or vehicles are in the way and it does not violate other traffic rules.
- Lanes are moving in the same direction: Unlike solid white lines, which indicate that lane changes should be avoided, dashed white lines show that vehicles in adjacent lanes are traveling in the same direction. This is important for safety since changing lanes in a situation where lanes move in opposite directions (like with yellow lines) would be dangerous.
- Not prohibiting passing: The dashed white line does not prevent passing. In fact, it is a signal that you can change lanes when necessary, provided it is safe and you are adhering to any other road signs or conditions (e.g., speed limits, intersections, etc.).
In contrast, solid white lines indicate that lane changes should be avoided, and yellow lines are used to separate lanes moving in opposite directions, with solid yellow lines generally prohibiting passing. Thus, dashed white lines are more permissive and help maintain flow and flexibility on multilane roads, promoting efficient driving without obstructing necessary lane changes.
