What does a yellow traffic light mean?

A yellow traffic light signifies that the signal is about to change to red, indicating that drivers should slow down and prepare to stop. This light serves as a warning for motorists to exercise caution and make a decision about whether it is safe to clear the intersection or stop.

When the light turns yellow, it is important to recognize that it is not an indication to speed up; doing so could lead to dangerous situations as other vehicles may already be in the intersection or preparing to stop. Additionally, while stopping is recommended, it should be done safely, without sudden or abrupt movements that could cause accidents. The light does not signal other specific actions such as turning left or stopping immediately without context of the situation—these decisions are based on the traffic conditions and distance from the stop line. Thus, understanding the purpose of the yellow light is critical for safe driving practices.
