What does a yellow traffic light mean?

A yellow traffic light serves as an important signal for drivers. It indicates that the red light is imminent, urging motorists to prepare to stop. When a yellow light appears, it is a warning that the light is about to change to red. This warning is designed to ensure safety by allowing vehicles and drivers to clear the intersection safely before the lights change completely.

While a yellow light does suggest that drivers should proceed with caution, it is primarily about signaling the forthcoming change to red, rather than just indicating safety or allowing for a continuation of movement. The expectation is that vehicles will come to a stop unless it is unsafe to do so – highlighting the need for awareness and readiness to stop. Thus, understanding this timing is crucial for maintaining proper traffic flow and ensuring safety on the roads.
