Pennsylvania DOT Driver’s License Knowledge Practice Test

Yielding the right-of-way at a four-way stop is critical for ensuring safety and smooth traffic flow. The correct answer highlights that if another vehicle is already in the intersection, you must yield to that vehicle. This rule is in place to prevent accidents and ensure that all drivers can navigate the intersection safely.

At a four-way stop, vehicles must come to a complete stop. The general rule is that the first vehicle to arrive at the intersection has the right of way. However, if another vehicle is already occupying that intersection, yielding is necessary regardless of the order of arrival. It prioritizes the safety of those already in the intersection and helps prevent conflicts and potential collisions.

The other choices represent situations where the right-of-way rules are quite different. Arriving first does not grant you the right-of-way if another vehicle is effectively already engaged in a turn or movement within the intersection. Being on the right might typically give you the right-of-way, but it is applicable only when multiple vehicles arrive simultaneously. Signaling from another driver indicates intent but does not automatically confer the right-of-way; the driver must still ensure they can proceed safely. Thus, yielding when another vehicle is already in the intersection is the safest and most crucial guideline to follow.
