Vehicles entering or crossing a roadway from a private driveway must yield to all oncoming vehicles. This is crucial for ensuring safety on the road, as vehicles already in motion on the roadway have the right of way. Yielding allows for a smooth merging into traffic, minimizing the risk of collisions.

In addition to oncoming vehicles, yielding to pedestrians is also an important consideration; however, the question specifically emphasizes oncoming vehicles, which underscores the broader responsibility of drivers leaving a private driveway to ensure they do not impede the flow of traffic. Understanding this rule helps maintain proper traffic order and prevents accidents.

Being aware of other vehicles and their rights while merging from a private driveway is vital for safe driving practices. This is why the correct answer highlights the necessity to yield to all oncoming vehicles, not just a specific type of road user.
