How to Interpret Traffic Signals for Left Turns?

[McSteven]

Here are the methods for interpreting traffic signals: When the green left arrow illuminates, left turns are permitted. If there is no dedicated left arrow signal and only a circular green light is present, left turns may proceed when the green light is active. Typically, the left turn phase follows the red light countdown, with straight-through traffic allowed only after the left turn countdown completes. Some intersections prohibit left turns entirely, so clear observation is essential. Relevant information: Road traffic signal lights constitute a category of traffic safety products. They serve as vital tools to enhance road traffic management, reduce traffic accidents, improve road utilization efficiency, and optimize traffic conditions. These signals are deployed at intersections such as crossroads and T-junctions, controlled by traffic signal controllers to ensure safe and orderly passage for both vehicles and pedestrians.
