What is the general sequence of a traffic signal?

The correct sequence of a traffic signal is designed to ensure safety and orderly traffic flow. The typical progression begins with the red light, which indicates that vehicles must stop. Following the red light, the yellow light serves as a warning that the signal is about to change from green to red, giving drivers time to either stop safely or prepare to proceed with caution. Finally, the green light signals drivers to go, allowing the flow of traffic through the intersection.

Understanding this sequence is crucial for drivers, as it helps them anticipate changes and respond accordingly to maintain safety on the roads. The emphasis on stopping first when the red light is displayed is fundamental to traffic regulations, aiming to prevent accidents and ensure that vehicles do not enter intersections when it is unsafe to do so.
