One of the most concerned is the positioning of the yellow light.
According to the relevant person in charge of the Ministry of Public Security, the violation of road traffic lights recorded 6 points, including red lights and yellow lights. According to international practice, parking should be done when the yellow light is on, and parking without parking is illegal. If any part of the car body has crossed the line when the yellow light is on, it can be driven past; if it is not over the line, it should be stopped by the brakes. Even if it crosses the zebra crossing, it should be stopped. As long as it stops, it will not be punished.
Some brothers think it is illegal to park the car in a traffic post.
And because of this uncertain yellow light concept, many taxis have become cautious when passing through intersections, even when they are very far away, they begin to glide and wait until the yellow light is fully on and then stop at the stop line.
So how do you define the yellow light?
The "Road Traffic Safety Law" stipulates that the yellow light indicates warnings and stipulates that motor vehicles should slow down when they encounter intersections. Vehicles that have crossed the stop line while the yellow light is on can continue to pass. Vehicles that have not crossed the stop line should stop. Yellow-lighting behavior is a violation of road traffic lights, and the driver will be fined between 20 yuan and 200 yuan, with 6 points.
How far can I stop the car from crossing? The historical data released by the DCCI Internet Data Center shows that even at 20 kilometers per hour, when the line is off the line at 5 meters, the line is turned on at 100%. If the warning is given eight seconds in advance, the vehicle may not be able to cross the line. The 7 groups of drivers traveled at a speed limit of 80 to 20 kilometers per hour. They found that the yellow light stepped on the brakes until the brake force was fully exerted. The average reaction time was nearly 1 second. The result of the braking distance was: 7 groups of drivers were driven at a speed limit of 80 to 20 kilometers. At 5 meters, all vehicles will cross the line when the yellow light is on; at a distance of 10 meters, only one vehicle with the lowest speed can stop the line; at a distance of 20 meters, the three vehicles with lower speed can be stopped; 40 In meters, five cars with lower speeds can stop; at 50 meters, six cars with lower speeds can stop, but cars with speeds of 80 kilometers per hour will still cross the line.
Xiao Bian believes that in recent years, drivers have lacked the necessary awareness of traffic safety, and even the yellow light originally used as a warning light has become an "accelerated warning light", which has led to the occurrence of various traffic accidents. Therefore, it is necessary to punish the Yellow Lights. If the new regulations can be implemented consistently, re-shaping the "warning" authority of the yellow light in people's minds, I believe that the road traffic safety governance is of great value.
Hydraulic support seal
Prevent leaks. Used in the category of hydraulic supports: drum ring, composite seal, mountain ring, bud ring, O-ring, etc. Generally rubber, polyurethane material.
Used together with the sealing ring, it has the functions of anti-crowding, guiding and reducing wear. It is generally made of phenolic XII cloth, 45% copper powder mixed with filled PTFE and other materials.
Guide ring:
It is a part used on the jack piston or piston rod to support the movement of the piston or piston rod. It can prevent the piston or piston rod from direct contact and friction with the cylinder during the movement, and protect the cylinder and the piston or piston. The rod is not damaged. Generally, it is polyoxymethylene, polytetrafluoroethylene and other materials.
Dust-proof ring: the main function is to go out and reciprocate the piston rod to expose the impurities attached to the outer surface of the cylinder, so as to prevent impurities such as external dust from entering the inside of the sealing mechanism. Generally rubber, polyurethane and other materials.

The revised version, known as the "most strict regulation in history," has been implemented for five days. It has been widely supported by people for their strict enforcement of red lights, driving calls, and not wearing seat belts.
