Is a Left Turn Allowed at a Red Light?

[BeauAnn]

At a red light, except for right turns (unless there is a red arrow pointing right), other vehicles are not allowed to make left turns or proceed straight. Below is relevant information about traffic signals: 1. Introduction: Traffic signals are lights that direct traffic flow, typically consisting of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light 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 signals at railway crossings. 2. Signal Light Source: LED (Light Emitting Diode) is a new type of light source developed for production, featuring low power consumption (current as low as 10~20mA), high brightness (light intensity can reach tens of thousands of mcd), small size (minimum diameter of 3mm), lightweight (a single LED weighs just a few tenths of a gram), and long lifespan (average lifespan of 100,000 hours). LEDs are gradually replacing incandescent and low-voltage halogen tungsten lamps in the production of road traffic signals.
