What must a driver do when they see a yellow light flashing at an intersection?

When a driver encounters a yellow light flashing at an intersection, the appropriate action is to approach cautiously and yield the right-of-way. This flashing yellow signal indicates that the driver should proceed with caution, as it alerts them to potential hazards or the presence of pedestrians or other vehicles.

By yielding the right-of-way, the driver ensures that they do not interfere with other traffic or pedestrians who may have the right to cross the intersection. It’s a signal to be vigilant and prepared to stop if necessary, rather than proceeding at full speed or ignoring the signal. This practice promotes safety for all road users and reduces the likelihood of accidents.

The other choices present actions that could lead to unsafe situations. Speeding up could result in a collision, stopping immediately might not be appropriate depending on the circumstances of the situation, and ignoring the signal poses significant risks to both the driver and others on the road.
