What should drivers do when approaching a red triangular traffic sign with "YIELD" on it?

Drivers approaching a yield sign are required to yield right-of-way to cars already traveling through the intersection, and must slow down or stop as required to do so. Specific legal requirements for obeying yield signs vary slightly from state to state.

Some yield signs have painted stop lines near them on the roadway, indicating that drivers are to stop at the line if it is necessary to come to a complete stop to yield the right-of-way. If these are not present, drivers are generally required to come to a complete stop at the earliest possible position that permits an unobstructed view of the intersection where the yield sign is located.
