On a public road, when are you allowed to pass another vehicle?

The correct answer emphasizes the importance of safety and adherence to traffic regulations when passing another vehicle. Passing on the left side can be permissible as long as it is done safely and without encroaching on the shoulder of the road. This practice helps to ensure that you maintain a safe distance from other vehicles and that the maneuver is executed in a controlled manner.

It's crucial to recognize that passing should only occur when proper visibility and road conditions allow for it, mixing with other vehicles safely without compromising safety. The absence of other traffic does not necessarily guarantee that it is safe to pass, as other factors could influence this decision. Similarly, passing when another vehicle is turning left or while you are turning right could lead to dangerous situations and is not considered safe. Hence, the selected answer reflects the set expectation that careful consideration of safety, road rules, and conditions is paramount when executing such maneuvers on public roads.
