An open intersection is one without traffic control signs or signals; when you enter one, you must yield the right-of-way if you __________.

An open intersection is defined as an intersection that lacks any traffic control signs or signals. In these situations, the right-of-way rules become crucial for safe driving. When entering an open intersection, yielding the right-of-way is necessary under various circumstances to ensure the safety of all road users.

When entering or crossing a state highway from a secondary road, it is important to yield to vehicles on the highway, as they are generally traveling at higher speeds. Similarly, when entering a paved road from an unpaved road, the vehicles on the paved road have the right-of-way because they typically experience more consistent traffic and have better visibility.

In addition, if you plan to make a left turn and there is an oncoming vehicle in the opposite direction, you must yield to that approaching vehicle. This ensures that you do not obstruct their path, preventing potential collisions.

Each of these scenarios highlights the necessity to yield the right-of-way in different driving situations at an open intersection, reinforcing safe driving practices. Therefore, recognizing that all of these circumstances require yielding demonstrates a comprehensive understanding of right-of-way rules at intersections, confirming why “all of the above” is the correct answer.
