Road traffic lights are a category of traffic safety products. They are an important tool for strengthening road traffic management,reducing traffic accidents,improving road use efficiency,and improving traffic conditions. Applicable to crossroads such as cross and T-shape,controlled by road traffic signal control machine to guide vehicles and pedestrians to pass safely and orderly.
1,green light signal
The green light signal is a permitted traffic signal. When the green light is on,vehicles and pedestrians are allowed to pass,but the turning vehicles are not allowed to obstruct the passing of straight-going vehicles and pedestrians.
2,red light signal
The red light signal is an absolutely forbidden pass signal. When the red light is on,no traffic is allowed. A right-turning vehicle can pass without obstructing the passage of vehicles and pedestrians.
The red light signal is a forbidden signal with a mandatory meaning. When the signal is violated,the prohibited vehicle must stop outside the stop line. The prohibited pedestrians must wait for release on the sidewalk; the motor vehicle is not allowed to turn off when waiting for release. It is not allowed to drive the door. The drivers of various vehicles are not allowed to leave the vehicle; the left turn of the bicycle is not allowed to bypass the outside of the intersection,and it is not allowed to use the right turn method to bypass.
3,yellow light signal
When the yellow light is on,the vehicle that has crossed the stop line can continue to pass.
The meaning of the yellow light signal is between the green light signal and the red light signal,both the side that is not allowed to pass and the side that is allowed to pass. When the yellow light is on,it is warned that the passage time of the driver and pedestrian has ended. It will soon be converted into a red light. The car should be parked behind the stop line and pedestrians should not enter the crosswalk. However,if the vehicle crosses the stop line because it is too close to the parking distance,it can continue to pass. Pedestrians who have already been in the crosswalk should look at the car,or pass it as soon as possible,or stay in place or return to the original place.
