What position do the red, yellow, and green lights occupy in a traffic light?

The correct arrangement of traffic lights is that the red light is positioned on top, followed by the yellow light in the middle, and the green light at the bottom. This configuration is standardized in many places to promote clear and consistent communication of traffic signals to drivers.

The red light at the top indicates that vehicles must stop, ensuring that they are safely halted before proceeding. The yellow light in the middle serves as a warning that the light is about to change to red, giving drivers a moment to prepare to stop if they haven't already done so. Finally, the green light at the bottom signals that it's safe for vehicles to proceed. This vertical arrangement is designed to ensure that drivers can easily recognize the state of the traffic signal from a distance, as the colors are arranged in a logical order that aligns with their meanings.
