On two-lane roads with traffic moving in opposite directions, when may you pass on the left?

Passing on the left on two-lane roads with traffic moving in opposite directions is permitted when there is a broken yellow line in your lane. The presence of a broken yellow line indicates that passing is allowed, as it signifies that the lane is open for overtaking other vehicles. This marking helps drivers understand when it is safe to pass another vehicle while ensuring they remain vigilant and considerate of oncoming traffic.

It's crucial to note that simply having a clear left lane does not guarantee that passing is safe; there may be other vehicles approaching. Similarly, a stop sign is not related to passing regulations on a roadway but rather to traffic control, meaning that this situation typically requires vehicles to stop. Regarding excessive speed, it is vital for drivers to adhere to speed limits for safety reasons and to avoid unintentionally making passing maneuvers that could be risky or against the law. Hence, the correct context for passing is indeed the presence of a broken yellow line.
