Here's some information about the Traffic Light :

At intersections, three-color traffic lights, which include red, yellow, and green, are positioned on all sides. These traffic lights function as silent "traffic police." They adhere to international standards for uniformity. The red light is a signal to stop, while the green light indicates it's safe to proceed. At intersections where vehicles converge from multiple directions, some need to go straight, while others must turn. The traffic lights dictate the right of way. When the red light is illuminated, it is forbidden to travel straight or turn left. However, a vehicle may turn right if it doesn't obstruct pedestrians or other vehicles. When the green light is on, vehicles are allowed to travel straight or turn. When the yellow light is illuminated, vehicles should come to a stop at the intersection's stop line or crosswalk line, and then proceed with caution. If the yellow light is flashing, it serves as a warning for vehicles to exercise heightened safety awareness.
