What does a white line on the road signify?

A white line on the road signifies the separation of lanes of traffic that are going in the same direction. This is important for maintaining order and safety on the road, as it helps drivers understand where they can safely move within their lane and when to change lanes. White lines indicate that the traffic flow in those lanes is aligned, thus providing a clear visual cue for drivers to ensure they are positioning their vehicles correctly.

The other options represent different road markings with distinct meanings. No parking zones are typically indicated by different signs or yellow lines, lanes designated for turning may be marked with specific symbols or arrows, and pedestrian crossings are marked with distinct crosswalk lines, typically in a different style or color to enhance their visibility to both drivers and pedestrians. Understanding the meaning of road markings, especially white lines, is crucial for safe driving practices.
