What must you do when a traffic light turns yellow?

When a traffic light turns yellow, the appropriate action is to come to a stop if it is safe to do so. A yellow light serves as a warning that the signal is about to change to red, indicating that vehicles should prepare to stop. It is important to assess the situation: if stopping can be done safely without causing an accident or endangering yourself or others, this is the proper response.

Speeding up to cross before the light turns red can lead to dangerous situations, such as running the red light or colliding with vehicles entering from the cross street. Ignoring the light because no one is around undermines traffic laws designed to maintain order and safety on the road. Similarly, proceeding quickly through an intersection when the light is yellow can also result in a violation if the light turns red while crossing, potentially resulting in accidents or legal repercussions. Understanding and responding appropriately to a yellow light is crucial for safe driving.
