Step-by-step explanation:
At an intersection with a yield sign, you should slow down and yield the right-of-way to other traffic. A yield sign indicates that you need to be cautious and let other vehicles already in the intersection or approaching it have the right-of-way. This means that you should adjust your speed and be ready to stop if necessary to allow other vehicles to pass safely.
