What does a dashed yellow line indicate?

A dashed yellow line indicates that passing is allowed for vehicles traveling in either direction, provided it is safe to do so. This marking indicates that the lane is open for overtaking slower vehicles, and drivers should ensure there is sufficient visibility and space before making a maneuver to pass. It promotes safer navigation on two-way roads where passing is permissible.

In this context, a solid yellow line would signify no passing is allowed, indicating to drivers that overtaking is unsafe due to potential hazards such as curves or obstructions in the roadway. Local roads and one-way streets are not represented by dashed yellow lines and have their own specific markings and rules governing their usage.
