What action should be taken when approaching an intersection with a yield sign?

When approaching an intersection with a yield sign, the appropriate action is to yield to oncoming traffic. This means that you should be prepared to slow down and stop if necessary to allow vehicles or pedestrians that have the right of way to pass before you proceed through the intersection. The purpose of the yield sign is to inform drivers that they must give way to other vehicles or pedestrians that are already in the intersection or are approaching from another direction.

Yielding does not necessarily mean coming to a complete stop unless it is required by the conditions (such as the presence of oncoming traffic). If the intersection is clear and there are no vehicles or pedestrians that need to be yielded to, you may proceed with caution. However, the key point here is the responsibility placed on the driver to assess the situation and yield appropriately, ensuring safety for all road users, which is reflected in the choice that indicates yielding to oncoming traffic.

The other options do not properly reflect the meaning of a yield sign and could potentially lead to unsafe driving behaviors. Speeding up could increase the risk of accidents, stopping for all vehicles isn't necessary and could cause traffic disruption, and ignoring the sign could result in dangerous encounters with other vehicles or pedestrians.
