What action should a driver take at a yield sign?

When approaching a yield sign, the appropriate action for a driver is to slow down and prepare to stop if necessary. The purpose of a yield sign is to indicate that the driver must yield the right-of-way to any traffic or pedestrians in the intersection or crossroad ahead. By slowing down, the driver can assess the situation and determine if it is safe to proceed without stopping, therefore complying with traffic regulations while ensuring safety.

The other options are not suitable in this context. Coming to a complete stop may be required in some situations, but it is not mandated at every yield sign unless there is oncoming traffic. Proceeding without stopping is inappropriate, as it can lead to accidents if other vehicles or pedestrians are present. Turning around and finding another route does not effectively utilize the yield sign’s intention and creates unnecessary detours. Therefore, slowing down and being prepared to stop is the most prudent action a driver can take at a yield sign, ensuring both compliance with traffic laws and the safety of all road users.
