Final answer:
The law requires you to slow down, stop if necessary, and yield the right-of-way to traffic when approaching a 'Yield' sign to ensure safety and regulate the flow of traffic.
Step-by-step explanation:
Upon approaching a "Yield" sign, the law requires you to slow down, stop if necessary, and yield the right-of-way to traffic approaching the intersection. This means that if there are other vehicles or pedestrians using the intersection, you must allow them to proceed before you enter. Ignoring a yield sign and not slowing down can jeopardize pedestrian safety and lead to accidents, as it would force pedestrians and other vehicles to dodge traffic that has not yielded. A yield sign serves a similar purpose to a traffic signal in that it helps to regulate the flow of traffic, although it allows for a more flexible response depending on the immediate conditions, instead of providing a fixed stop-and-go pattern.
