What does it mean if the traffic light turns yellow?

When a traffic light turns yellow, it serves as a warning for drivers that the light will change to red shortly. This is a crucial signal indicating that you should prepare to stop if it's safe to do so. The purpose of the yellow light is to provide a transition phase; it reminds drivers to slow down and be ready to stop before the light changes.

This signaling helps to prevent accidents that could occur from vehicles trying to rush through an intersection on a red light. The yellow light does not imply that it's safe to enter or accelerate through the intersection; rather, it emphasizes the need for caution and awareness of the impending red light, reinforcing the importance of maintaining control over the vehicle and ensuring the safety of everyone on the road.
