Introduction:

Traffic lights are signal lights that direct traffic operations, usually consisting of red, green, and yellow lights. Red light indicates prohibition of passage, green light indicates permission to pass, and yellow light indicates warning.

Traffic signals are divided into motor vehicle signals, non motor vehicle signals, pedestrian crossing signals, direction indicators (arrow signals), lane signals, flashing warning signals, and road and railway level intersection signals.

Motor vehicle signal lights and non motor vehicle signal lights

Motor vehicle signal lights are a set of lights composed of three circular units without patterns of red, yellow, and green, which guide motor vehicles to pass.

Non motorized vehicle signal lights are a set of lights composed of three circular units with bicycle patterns inside, red, yellow, and green, guiding the passage of non motorized vehicles.

When the green light is on, vehicles are allowed to pass, but turning vehicles must not obstruct the passage of passing vehicles or pedestrians.

When the yellow light is on, vehicles that have crossed the stop line can continue to pass.

When the red light is on, vehicles are prohibited from passing.

At intersections without non motorized vehicle signal lights and pedestrian crossing signal lights, non motorized vehicles and pedestrians should follow the instructions of the motorized vehicle signal lights.

When the red light is on, vehicles turning right can pass without obstructing the passage of vehicles or pedestrians being cleared.
