How to Correctly Read Traffic Signals?

[Lacey]

Traffic signals consist of three colors: red, green, and yellow. Red indicates no passage, green indicates passage is allowed, and yellow serves as a warning. Traffic signals are categorized into: motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator signals (arrow signals), lane signals, flashing warning signals, and railway crossing signals. At intersections, you can see three-color traffic signals hanging on all four sides, functioning as a silent "traffic police". Traffic lights are internationally standardized signals. The red light is a stop signal, while the green light is a go signal. At intersections, vehicles from several directions converge here, some going straight and others turning. Determining who proceeds first is governed by the traffic lights. When the red light is on, vehicles are not allowed to go straight or turn left, but right turns are permitted if they do not interfere with others or vehicles. When the green light is on, vehicles are allowed to go straight or turn. When the yellow light is on, vehicles that have already passed the stop line or pedestrian crossing may continue. A flashing yellow light warns vehicles to pay attention to safety.
