Hello everyone, I'm Xiao Li. There was a flat tire in the car on the highway, and many people didn't know whether to call for help or stop in the emergency lane. Some people feel that shouting rescue team on the highway, even if the rescue vehicle sets off as soon as possible, it will take a long time to arrive, in order to avoid waiting too long on the emergency lane and a second accident, you should call rescue first. Regarding this problem, today Xiao Li will tell you the correct approach, novices must understand.
In the event of a puncture on the highway, turn on the double flashing lights as soon as possible, unless your car is no longer moving, you must move the car to the emergency lane as soon as possible, which is the most basic common sense of driving on the highway. Although it takes a long time for the rescue vehicle to come, and our car stays in the emergency lane for more than one minute, the more dangerous it is, but the car is more dangerous in the middle of the lane.
On the highway, many people are driving at a speed of 120, and everyone knows that this speed is very fast, but we may not have any idea how fast it is. It is no exaggeration to say that one breath is almost a second, and in the time of this breath, a car driving at a speed of 120 kilometers per hour can run more than 30 meters. If you have a flat tire on the highway, when there is a car behind you to see you, the braking distance plus the reaction time must be at least more than 100 meters to brake the car, in case someone does not react in time, it will hit it directly, which is very, very dangerous, many serial traffic accidents are often due to the rear car avoidance is not timely to hit one after another, not that they don't want to brake but really too late.
Therefore, after the puncture, the car should be moved to the emergency lane as soon as possible, and the position of about 150 behind the rear of the car is placed with a warning triangle, if there is no warning triangle, then take the branches on the side of the road to replace, and all the people in the car should be evacuated to the outside of the guardrail to wait for rescue. If you are able to change the spare tire, leave one person to change the spare tire, and the others evacuate outside the guardrail. However, it should be noted that when changing the spare tire, you must place a warning triangle and turn on the double flashing lights to operate, otherwise you may be deducted points. In fact, when we drive on the highway, the problem of vehicle puncture can be prevented, and many tires will burst because of our negligence in inspection. Regarding how to prevent punctures, I have 3 suggestions for you.
First, check the tire pressure before getting on the highway. There are many cars running on the road that do not have the function of tire pressure detection, we must check the tire pressure before going to the highway, the tire pressure can not be too high, nor too low, generally keep it between 2.2 and 2.8. Some people's cars have a tire pressure display function, see the tire pressure is lower than 1.9 alarm, feel that you can still be too lazy to inflat, this is also a safety hazard, the tire pressure is too low than the tire pressure is too high is more likely to burst. Because when the tire pressure is too low, the tire wall is stressed more and heats up, which is more likely to break through the critical point and puncture.
Second, don't use tires that are too old for a long time. The shelf life of tires is 5 years, and generally you have no problem using 6 years, but the limit is 7 years, and tires that have been used for 7 years must be replaced. Because tires that have expired for so long will be aged, all aspects of the tires have long been below the safety level, and they are the most likely to burst when running at high speeds.
Third, check the tire wear to rule out trauma. Abnormal tire wear, we can see at a glance by looking at the tread, the tread pattern is almost gone, that is, the wear is serious and can not be continued, but whether the tire has external injuries should be carefully checked. Many tires don't look like anything on the surface, but the inside has long been scratched by something hard, and you can't really see it if you don't look closely. This type of tire is not very prone to punctures, and this must be ruled out before going to high speeds.
After doing the above 3 points, the probability of a puncture at high speed will become very, very low, unless you are unlucky enough to press something sharp at high speed, otherwise you will not easily puncture the tire. Once you are unlucky and have a puncture, then you must not hesitate to move the car to the emergency lane as soon as possible, and set up safety warning signs to wait for rescue, which is the right way.
