What does a white dashed line signify?

• A. It separates lanes of traffic moving in opposite directions
• B. It marks a no-passing zone for vehicles
• C. It separates lanes of traffic moving in the same direction and allows lane changes
• D. It indicates that a stop is required at the line

Answer: (C)

A white dashed line is used to indicate that the lanes of traffic are moving in the same direction and that changing lanes is permitted. This marking helps drivers understand that they can safely switch between lanes when necessary, provided it is done with caution and without disrupting the flow of traffic. The presence of the dashed line indicates there are no prohibitions on lane changes in that area, as long as the driver has checked for oncoming vehicles and can maneuver without endangering themselves or others. In contrast, solid lines, whether white or yellow, generally indicate that a lane change should not be made. Knowing the function of these road markings is crucial for safe and efficient driving. The other options do not align with what a white dashed line signifies; for example, a solid line would be used for no-passing zones or to indicate stop lines, not a dashed line.
