A yellow traffic light serves as a warning to drivers that the light is about to change to red. It is important for drivers to understand that upon seeing a yellow light, they should be prepared to stop safely before the intersection. This warning period is essential for maintaining safe traffic flow, as it advises vehicles that must still cross the intersection to do so with caution, while informing those who are approaching that they need to slow down and prepare to halt.

The other options misinterpret the signal's meaning: suggesting that it indicates readiness to go or that the intersection is clear would lead to unsafe driving behavior and increased risk of accidents. Driving with the understanding that a yellow light means to stop helps ensure both the driver’s safety and the safety of pedestrians and other road users.
