What do white road markings indicate?

White road markings primarily indicate that the traffic lanes are moving in the same direction. This is important for maintaining orderly flow on the road and ensuring that vehicles stay within their designated lanes. When you see solid or dashed white lines, it informs drivers that lane changes are permitted but they should proceed with caution, as all vehicles in these lanes are traveling in the same direction.

Additionally, while some other markings—such as crosswalks—may utilize white lines, the specific context makes it clear that those do not represent the general usage of white markings. Understanding this helps drivers navigate roads safely by adhering to the intended lane directions and rules.
