What does a yellow lane mark separate?

A yellow lane mark is used to separate vehicles traveling in opposite directions. This is important for road safety, as it clearly delineates lanes for oncoming traffic, helping drivers stay in their designated lanes and reducing the risk of head-on collisions. Yellow lines indicate that overtaking or crossing into the opposing lane is generally prohibited unless otherwise specified, such as in certain passing zones.

In contrast, lane markings that separate vehicles traveling in the same direction are typically white. Other options, such as separating different vehicle types or different areas, do not accurately reflect the purpose of yellow lane markings. Understanding this distinction is crucial for safe driving and adherence to traffic regulations.
