A single broken yellow centerline indicates what on a two-way road?

A single broken yellow centerline on a two-way road signifies that passing is permitted if conditions are safe. This means that drivers can legally overtake vehicles in their lane when there is no oncoming traffic approaching and when visibility allows for such maneuvers. The broken line indicates that the roadway is shared between traffic moving in opposite directions, and it is a signal to drivers that they can exercise caution and merge into the oncoming lane to pass slower vehicles.

In contrast, solid lines, whether yellow or white, typically indicate that passing is prohibited, as they signal safer driving conditions or other restrictions. The concept of only allowing left turns or suggesting that the road is one-way does not apply to a broken yellow line; it specifically pertains to the rules of passing in a two-way traffic scenario. Understanding these markings helps drivers make informed and safe decisions while navigating roads.
