What does a yellow traffic light indicate to drivers?

A yellow traffic light serves as a warning signal to drivers, indicating that they should prepare to stop because the light is about to change to red. This transitional signal is crucial for maintaining safety at intersections, as it alerts drivers that their right to proceed is coming to an end very soon.

When a driver sees a yellow light, it is important to assess their distance from the intersection and their ability to stop safely. The rule is not to accelerate or attempt to clear the intersection if stopping can be accomplished safely. This understanding helps prevent accidents and ensures smoother traffic flow. By preparing to stop, drivers can react appropriately and avoid potential collisions with vehicles that might be entering the intersection on the green light afterward.

Thus, the message conveyed by the yellow light is one of caution and readiness rather than continued motion or urgency to change direction, as implied by other choices.
