A man in Zhoukou suffered a flat tire on the highway going home to visit relatives. what should he do ？

When driving at high speed on the expressway, a flat tire is definitely an unexpected situation that we don't want to encounter, but it is very likely to encounter. In this case, we must deal with it calmly.

First of all, when there is a flat tire, don't panic, don't let the vehicle get out of control, don't let the vehicle change lanes quickly, and don't brake suddenly. Hold the steering wheel tightly, release the accelerator, and slowly slow down the speed. At the same time, pay attention to the vehicles coming from the rear, flash double lights and turn signals, and park the vehicles safely and smoothly in the emergency lane.

Secondly, let all passengers get off and go outside the high-speed guardrail. At the same time, put a triangle warning sign at the rear of the car about 150 meters to remind the rear car.

In addition, check the vehicle. Usually there is a spare tire in the car. Just change it step by step. It is not difficult to prepare tools such as jacks and wrenches and change a spare tire. If there is no spare tire in the car, or you can't change it yourself, you can only call for help. In the process of replacing the spare tire, be sure to pay attention to the rear vehicles, don't stay on the highway, and replace them quickly.

Therefore, you must carefully check the vehicle before getting on the expressway to avoid a flat tire.

First of all, aged and excessively worn tires should be replaced in time. There is a wear line on the tire. When it reaches the wear line, it is better to replace the tire even if it can still be used. A good tire may have some hard objects such as stones in its lines, so clean them up before getting on the highway.

Secondly, the tire pressure should not be too high or too low. Because of thermal expansion and contraction, the tire pressure on urban roads will increase in different degrees at high speed, and there should be a margin before high speed.

Moreover, drive safely and don't walk beside the guardrail. One is not to drive too fast, and the other is to pay attention to the situation on the road. Generally speaking, there are some stones and broken glass beside the guardrail, so it is safer to take the middle lane.

The Mid-Autumn Festival is coming. Many people who leave home will drive home for reunion, and the traffic on the road will increase. Be sure to pay attention to driving safety at this time. Prevention is the most important thing, because if there is a flat tire, some drivers will not be able to react and it is easy to have a second accident.
