When is it permissible to drive in the opposite lane of a two-lane roadway?

Driving in the opposite lane of a two-lane roadway is permissible only when it is safe to do so and if there is a dashed yellow line indicating that passing is allowed. The dashed yellow line serves as a clear visual indicator that drivers may cross the centerline to overtake another vehicle when conditions allow it, such as when there is no oncoming traffic, and the maneuver can be completed safely.

This rule is put in place to enhance roadway safety and ensure that drivers are aware of when passing is permissible. The requirement of a dashed yellow line is crucial because it delineates areas where overtaking is considered safe, as opposed to areas where solid lines indicate that such maneuvers are prohibited due to potential hazards. Safety is always the top priority, and following these markings helps reduce accidents and keep all road users secure.

Other options do not align with traffic safety standards; just feeling safe to pass or considering daylight hours alone does not take into account the critical visual indicators and conditions necessary for safe passing.
