What is the traffic light sign?
1 Answers
The traffic light sign has three types: the red light indicates prohibition of passage, the green light indicates permission to pass, and the yellow light serves as a warning. Initially, there were only red and green lights, but after improvements, a yellow light was added. Red Light: Mainly includes three types: Command light signal: When the red light is on, vehicles and pedestrians are not allowed to pass; vehicles must stop behind the stop line, and pedestrians must wait at the roadside of the crosswalk; Lane light signal: Generally installed above lanes that require separate command, it only directs vehicles traveling in that lane, while vehicles and pedestrians in other lanes still follow the regular signal; Crosswalk light signal: When the red light is on, pedestrians are not allowed to enter the crosswalk. Green Light: Mainly includes three types: Command light signal: When the green light is on, vehicles and pedestrians are allowed to pass, whether motorized or non-motorized; all facing the green light signal can proceed straight or turn left or right. Vehicles entering the intersection during the green light should yield to vehicles already in the intersection and pedestrians in the crosswalk. Lane light signal: When the green arrow light is on, vehicles are allowed to proceed in the direction indicated by the arrow. The green arrow light refers to a traffic command signal light within the green light that includes left-turn, straight, and right-turn directional arrows. Crosswalk light signal: When the green light is on, pedestrians are allowed to cross the crosswalk; when the green light flashes, pedestrians are not allowed to enter the crosswalk, but those already in the crosswalk may continue to cross. Yellow Light: Mainly includes two types: When the yellow light is on: Vehicles and pedestrians are not allowed to pass, but vehicles that have already crossed the stop line and pedestrians already in the crosswalk may continue to pass; When the yellow light flashes: Vehicles and pedestrians must pass under the principle of ensuring safety.
