What is the meaning of a yellow traffic light?

A yellow traffic light serves as a warning that the signal is about to change to red, indicating that drivers need to prepare to stop if it is safe to do so. It signifies that the light is transitioning and therefore requires motorists to assess their surroundings and make a decision.

The key concept here is that the yellow light is not an invitation to continue driving at the same speed; instead, it urges caution. Drivers should slow down and be ready to stop, especially if they are approaching the intersection. This is crucial for maintaining safety on the road, as it helps prevent accidents when the light changes to red.

The indication that the light is yellow and transitioning to red means that caution is necessary—drivers must evaluate their ability to stop safely without entering the intersection after the signal changes. This is essential for allowing time for traffic clearances and ensuring pedestrian safety.
