What does a yellow traffic light mean?

A yellow traffic light serves as a warning to drivers that the signal is about to change to red. When you see a yellow light, it indicates that you should prepare to stop safely, rather than rushing through the intersection. This allows for a smooth transition, ensuring that vehicles have the opportunity to clear the intersection before the light turns red, thus helping to maintain order and safety on the roads.

The intention behind the yellow light is to prevent sudden stops that could lead to collisions, and to inform those approaching an intersection that they should be ready to stop if it's safe to do so. Understanding this aspect of traffic signals is crucial for all drivers, especially commercial drivers who may be operating larger vehicles that require more time and distance to stop.
