What do yellow pavement markings on the road indicate?

Yellow pavement markings primarily indicate the separation of traffic moving in opposite directions. They play a crucial role in road safety by helping drivers understand where they can pass or where lanes are designated. In this case, the correct answer is that yellow markings indicate no passing zones, often represented by solid or broken lines.

Solid yellow lines indicate that passing is not allowed in that area, ensuring that drivers remain in their lane for safety reasons. This is particularly important on two-lane roads where vehicles may be traveling in both directions, as it helps prevent head-on collisions that can occur if drivers attempt to pass unsafely.

While options about the right and left edges of a roadway or pedestrian crosswalks pertain to other markings – specifically white lines for edges and crosswalks – these are not indicated by yellow markings. Thus, it’s vital to recognize that yellow lines have specific functions related to traffic flow and safety on roads.
