What Are the Types of Traffic Signals?
1 Answers
Traffic signals can be categorized into seven major types based on their functions. Here are the detailed descriptions: Motor Vehicle Signal Lights: These consist of a set of three circular units displaying red, yellow, and green lights, guiding the passage of motor vehicles. Non-Motor Vehicle Signal Lights: These are composed of three circular units with bicycle symbols inside, displaying red, yellow, and green lights, directing non-motor vehicle traffic. Pedestrian Crossing Signal Lights: These signals, consisting of red and green lights, are installed at both ends of pedestrian crossings. Lane Signal Lights: A green arrow light permits vehicles in the lane to proceed in the indicated direction, while a red cross or arrow light prohibits lane traffic. Directional Indicator Signal Lights: These signals display arrows pointing left, upward, or right, indicating left turn, straight ahead, or right turn, respectively. Flashing Warning Signal Lights: These are continuously flashing yellow lights, alerting vehicles and pedestrians to proceed with caution after confirming safety. Railway Crossing Signal Lights: When two red lights flash alternately or a single red light is on at a railway crossing, it prohibits vehicles and pedestrians from passing. When the red light turns off, passage is permitted.
