Which Light to Watch for Left Turns at Intersections?

[LaLily]

If the intersection only has a circular light, proceed with the left turn when it turns green; if there is a left-turn arrow light, also check if there is a left-turn waiting area on the ground. If present, you can enter the waiting area when the straight-through light is green and then complete the left turn once the left-turn arrow light turns green. Below is an introduction to traffic signal lights: 1. Function of traffic signal lights: Traffic signal lights are lights that direct traffic flow, typically consisting of red, green, and yellow lights. A red light means stop, a green light means go, and a yellow light serves as a warning. 2. Classification of traffic signal lights: Traffic signal lights are categorized into motor vehicle signal lights, non-motor vehicle signal lights, pedestrian crossing signal lights, directional indicator lights (arrow signal lights), lane signal lights, flashing warning signal lights, and railway crossing signal lights.
