What are the precautions for driving at high temperature?

In the hot season, drivers must ensure that they have enough rest and sleep time and maintain strong physical strength and energy. When you feel tired, you should stop in the shade and rest, and then go on the road after your physical strength is restored. Don't drive just to grab time. Pay attention to the following points when driving in hot weather: 1. Don't wear sunglasses that are too dark. The dark color of sunglasses will delay the time for the eyes to send images to the brain. This visual delay causes speed perception distortion, which makes 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. 2, don't fatigue driving, the temperature is high in summer, 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. 3. Prepare drinking water and water in the water tank. By preparing the required water, the driver can avoid being upset and anxious due to the lack of water in the middle, provide enough water for the car, and prevent the car from high temperature failure when driving at high speed for a long time. 4. Fire extinguishers and triangle warning signs should be placed in the car. In hot weather, when vehicles sometimes spontaneously ignite or other fires occur, fire extinguishers can be used at any time. At the same time, in the event of an accident, the warning sign must be placed at the direction 150 meters from the rear to avoid a series of accidents. 5. Beware of spontaneous combustion and puncture. Generally speaking, spontaneous combustion is related to line aging and oil leakage. Therefore, in summer, it is necessary to check whether the high and low voltage lines of vehicles are short-circuited or aging, and whether the oil circuit leaks oil. The daily maintenance of the car is the key, so it should be maintained frequently. At the same time, tire puncture is also a traffic safety hazard. With the gradual increase of air temperature and road surface temperature, when driving at high speed or long distance, the tire pressure is easy to rise, leading to tire puncture. Therefore, we should pay more attention to the tire pressure in summer and choose the appropriate tire pressure to drive.
