What must road user "A" potentially do for road user "B" when yielding?

When road user "A" is yielding to road user "B," the most pertinent action is to stop if necessary. Yielding means that road user "A" must give the right of way to road user "B," allowing them to proceed without interference. Stopping helps ensure that road user "B" can continue safely, particularly in situations such as when entering an intersection or merging onto a roadway where traffic is already present.

While changing direction, speeding up, or signaling can be part of the broader context of safe driving and yielding, they do not directly denote the required action of yielding. For instance, changing direction might not always be feasible or safe, and speeding up could lead to dangerous situations where road user "B" might not expect such behavior. Signaling, while important for communication, does not replace the responsibility of stopping when needed to fully yield the right of way. Thus, stopping is the clearest and most direct way for road user "A" to yield effectively to road user "B."
