Things to pay attention to when driving in hot summer, these 10 points should be paid attention to
Fatigue driving, spontaneous vehicle combustion, and over-limit transportation are the main reasons for frequent traffic accidents in summer. When driving in hot weather, please pay attention to the following points:
1. Do not wear sunglasses that are too dark.
The dark color of sunglasses can delay the time for the eyes to send images to the brain. This visual delay in turn distorts the perception of speed, causing drivers wearing sunglasses to make incorrect judgments. Studies have shown that dark sunglasses can extend a driver's response time to an emergency by 100 milliseconds and increase the emergency braking distance by 2.2 meters.
2. Don’t drive while fatigued
The temperature is high in summer and it is easy to get tired and doze off. Therefore, it is necessary to maintain enough sleep time to ensure that you are energetic. If you feel sleepy while driving, you should stop in time, take a proper rest, and then continue driving when your mind is clear.
3. Prevent spontaneous combustion of the car
Before traveling, be sure to check whether the high and low voltage lines of the vehicle are short-circuited or aged, whether the plugs are loose, whether the battery is in normal working condition, and whether the oil circuit is Is there any oil leakage, etc.? Equip a fire extinguisher in the car and be familiar with how to operate it to prevent accidents.
4. Don’t eat too many cold drinks
When driving, most of the blood will flow to the tensely active muscles to supply sufficient nutrients and transport away waste. In this way, The blood supply to the gastrointestinal tract is temporarily reduced. If a large amount of cold drinks are consumed, it will cause a sudden contraction of the blood vessels in the gastrointestinal tract, reducing blood flow, often causing physiological dysfunction, affecting the body's digestion of food, and causing gastrointestinal diseases such as stomachache and diarrhea.
It is better to drink hot tea than cold drinks in summer. Drinking hot tea can dilate capillaries, open sweat pores, relax sweat glands, and perspire smoothly, which is beneficial to dissipating body heat. Moreover, theophylline in tea also has a diuretic effect, increasing urination and taking away part of the heat.
5. Check the air pressure of car tires frequently
As the temperature of the car and the road surface gradually increase, and when driving at high speed or long distances, the tire pressure can easily rise, causing a tire blowout. For safety reasons, please stop frequently to reduce your blood pressure.
6. Be extra careful when driving
When the weather is hot, people like to use umbrellas to block the sun. In order to block the sun, the height of the umbrella is generally relatively low, blocking the eyes of the person holding the umbrella. sight. Therefore, you must be extra careful when driving, especially when overtaking or turning.
7. Do not drive while wearing slippers
If an emergency occurs while driving in slippers, if the slippers do not follow your feet when you step on the accelerator or brake, it is likely to delay the braking opportunity and cause a traffic accident. .
8. It is not advisable to use gas lighters
The heat wave is rolling in midsummer, and some drivers have the habit of smoking to relieve fatigue. After lighting the cigarette, the gas lighter is usually placed on the dashboard. This is very dangerous. For disposable gas lighters, the plastic container containing liquid gas will expand when heated above 40 degrees Celsius. Plastic casings can explode due to heat. Although the explosive power of a gas lighter is not great, when it is placed together with some oil, flammable materials, etc. in the car, once it explodes, it can easily cause a fire with disastrous consequences. Therefore, in hot summer, drivers should not use gas lighters. Besides, smoking while driving is not allowed.
9. It is not advisable to turn on the air conditioner for a long time
Vehicles equipped with air conditioners have better sealing performance. Most people will feel dizzy, tired, and have memory loss after staying in this environment for a few hours. This is because when the engine is idling, the gasoline is not completely burned and carbon monoxide is produced. At the same time, the people in the car exhale a large amount of carbon dioxide, which sharply reduces the oxygen in the car. Therefore, the working status of the air conditioner should be appropriately adjusted, or the car windows should be opened for ventilation every once in a while.
10. Precautions for parking vehicles
Do not park your vehicle in places such as large trees, billboards, zero-hour fences, etc. when there are thunderstorms in summer and strong winds and heavy rain; if the rainfall is too heavy, Try to park your vehicle where drainage is smooth or on higher ground. If the vehicle has been flooded, do not ignite it and notify the insurance company and 4S store immediately.
