Drivers' safety precautions in summer: 1. Don't drive tired: in summer, the days are long, the nights are short, the temperature is high, and physical exertion is high, especially at noon, which makes it easy to doze off. So keep enough sleep time and ensure energy. If you feel sleepy during driving, you should stop in time, rest for a while, and then continue driving. 2, the correct choice and use of sunglasses: sunny in summer, many friends will wear sunglasses when driving. Don't choose dark sunglasses when choosing sunglasses, try to choose polarizers, because polarizers can filter out harmful light and make your eyes less tired when driving. Research shows that dark sunglasses can prolong the driver's reaction time to the situation 100 milliseconds and increase the braking distance by 2.2 meters. 3. Driving without slippers: Don't be greedy for coolness when driving, because slippers and feet are not fixed, and it is easy to sweat in summer. It is easy to get into danger when driving in an emergency. In addition, it is dangerous to drive in high heels. It is suggested to put a pair of flat shoes in the car and change them when driving. 4. Don't sleep in a closed car: Many people choose to rest in the car after driving fatigue. Be careful not to close the window and turn on the air conditioner to rest in the car when driving fatigue; Fresh air can't enter the closed compartment space, and it is very dangerous to sleep in the car and cause suffocation. 5, refuse road rage: drivers and friends will become a little impatient on hot roads. Everyone must be calm and drive safely. 6. High-temperature explosion-proof tires in summer: The road surface temperature in summer is often above 60 degrees Celsius. When the car is driving for a long time, tire burning will occur when the tire temperature rises and the rubber is easy to soften seriously, and the air pressure in the tire will also rise, which will easily lead to tire puncture. Most puncture cases are often caused by high tire pressure.
