In hot weather, people like to use umbrellas to shade the sun, but in order to keep out the sun, the height of umbrellas is generally low, which blocks the view of umbrella holders. Therefore, drivers must be extra careful when driving, especially when overtaking and turning.

2. Always check the tire pressure.

With the gradual increase of air temperature and road surface temperature, the tire pressure is easy to rise when driving at high speed or long distance, resulting in tire puncture. For the sake of safety, please stop often.

Never drive with slippers.

In summer, female friends like to wear slippers, which are beautiful, convenient and cool, and some even drive in slippers.

In fact, this practice is very dangerous. In an emergency, if the slippers don't keep up with the feet when stepping on the accelerator or braking, it is likely to delay the braking opportunity and cause traffic accidents.

4. Gas lighters should not be used.

The heat wave is rolling in midsummer, and some drivers have the habit of smoking to relieve fatigue. After the cigarette is lit, the gas lighter is usually conveniently placed on the dashboard. This is very dangerous. Disposable gas lighters contain liquid gas in their plastic containers. When the temperature is above 40 degrees Celsius, the gas will expand when heated. The plastic shell will explode when heated. Although the explosive power of gas lighters is not great, when they are put together with some oil and combustible materials in the car, once they explode, it is easy to cause a fire, and the consequences are unimaginable. Therefore, drivers should not use gas lighters in hot summer. Besides, smoking is not allowed while driving.

5. It is not advisable to wear dark sunglasses.

The dark color of sunglasses will delay the time for eyes to send images to the brain, which will cause speed perception distortion and make drivers wearing sunglasses make wrong judgments. Research shows that dark sunglasses can prolong the driver's reaction time to emergency 100 milliseconds and increase the sudden braking distance by 2.2 meters.

6. Avoid fatigue driving and angry driving.

In summer, the temperature is high, the physical exertion is high, especially at noon, and it is easy to get tired and doze off. So keep enough sleep time and ensure energy. If you feel sleepy during driving, you should stop in time, take a proper rest for a while, and then continue driving after your head is clear.

In addition, hot weather can also lead to irritability. Therefore, car owners and friends should never drive in anger. They should always keep calm and obey the traffic rules.

7, beware of spontaneous combustion

There are several spontaneous combustion accidents every summer. Therefore, before going out, you must check whether the high and low voltage lines of the vehicle are short-circuited or aging, whether the plug is loose, whether the battery is in normal working condition, and whether the oil circuit leaks oil. In addition, flammable and explosive articles such as gas lighters should also be cleaned up in time. It is necessary to equip the car with fire extinguishers and master the operation methods skillfully to prevent accidents. In addition, it is also a good idea to insure the insurance company against spontaneous combustion loss.

8. Cold drinks should not be overeating.

It's hot in summer, drivers sweat a lot, are often upset and thirsty, and often want to eat cold drinks. But some people eat a lot, so overeating is not good for their health. Because when the driver drives, most of the blood will flow into the tense muscles to supply enough nutrition and take away the waste, thus temporarily reducing the blood supply to the gastrointestinal tract. At this time, if a large number of cold drinks such as ice cream are ingested, the blood vessels in the gastrointestinal tract will suddenly contract and the blood flow will decrease, which will often cause physiological dysfunction, affect the digestion of food, and cause gastrointestinal diseases such as stomach pain and diarrhea.

So, how should we drive to quench our thirst in summer? Experts point out that drinking cold drinks in summer is not as good as drinking hot tea. Drinking hot tea can dilate capillaries, open sweat pores, relax sweat glands and sweat freely, which is beneficial to heat dissipation in the body. Moreover, theophylline in tea also has diuretic effect, which can increase urination and take away some calories.

It is not advisable to turn on the air conditioner for a long time.

When the engine is running at idle speed, the gasoline burns incompletely, which will produce carbon monoxide. Generally, air-conditioned vehicles have better sealing performance. Most people will feel dizzy and tired after staying in this environment for a few hours, and their memory will also decline. At the same time, the people in the car exhaled a lot of carbon dioxide, which drastically reduced the oxygen in the car.
