The use of red, yellow, and green lights in traffic signals was introduced to regulate and control vehicular movement. The green light, being the third and final signal in the sequence, indicated that it was safe for drivers to proceed.

A green light is a signal that allows vehicles and pedestrians to move forward or turn, depending on the specific rules of the intersection. It is part of a traffic light system that controls movement to ensure safety and organization on roads. The green light usually follows a red or yellow light, indicating that waiting vehicles can proceed. However, in some cases, drivers must still let pedestrians or other vehicles go first before moving. Traffic lights help manage the flow of movement and reduce the chances of accidents.
