What does a yellow traffic light indicate?

A yellow traffic light signals drivers to prepare to stop if it is safe to do so. This warning indicates that the light is about to change to red, and drivers should be cautious. The intent behind this signal is to alert drivers that they should be reducing their speed and getting ready to stop at the intersection. It plays a crucial role in preventing collisions, as it gives drivers a brief moment to assess their surroundings and make a safe decision regarding whether to stop or proceed through the intersection based on their distance from the traffic signal.

Other choices do not accurately represent the meaning of a yellow light. Speeding up to pass through an intersection can lead to dangerous situations, especially if the light changes to red as the driver approaches. Preparing to park does not relate to the indications given by a yellow light, while yielding to pedestrian traffic is typically a consideration when a signal shows red or when pedestrians have the right of way, rather than in the instance of a yellow light. Understanding the meaning behind traffic signals is essential for safe driving and ensuring the flow of traffic.
