What does it mean when a traffic light turns yellow?

When a traffic light turns yellow, it signals drivers to prepare to stop because the light is about to turn red. This is a critical moment in traffic control as it helps prevent accidents by indicating that the opportunity to safely proceed through the intersection is ending. The yellow light serves as a warning to approach the intersection with caution and to make a decision based on the circumstances.

Drivers should assess how close they are to the intersection and whether they can safely stop before the light changes to red. It’s important to recognize that speeding up to cross the intersection before the light turns red can lead to dangerous situations, including collisions with vehicles approaching from cross streets or pedestrians who may be crossing. Ignoring the light or proceeding at high speed does not align with safe driving practices, as it increases the risk of accidents. The yellow light is not an indication to continue without caution or disregard for the traffic rules; rather, it is a vital signal for maintaining safety on the road.
