Hail is generally divided into three levels, the first level is light hail, the hail diameter is not more than 0.5 cm, the impact force is not too great, and the cumulative hail falling time is not more than 10 minute; The secondary hail is medium hail, the hail diameter is more than 0.5 cm but not more than 2 cm, and the cumulative hail time is less than half an hour; The third level is heavy hail, the hail diameter is more than 2 cm, and the cumulative hail time is more than 30 minutes. In hail weather, the following preventive measures should be taken:

1. Close doors and windows, properly place outdoor items and move them to a safe place to avoid being damaged by hail impact. It is best to transfer the vehicles parked in the open air to the indoor parking lot, because hail can easily damage the windows and windshield.

Please don't go out at will in hail weather, especially for the elderly and children. Hail weather is often accompanied by violent storms, which are easy to blow down things on the street and cause harm to pedestrians. At the same time, the road surface is prone to water accumulation, which is in danger of electric shock and falling.

3. It is best not to open an umbrella easily in hail weather, and the umbrella is easily blown over by strong wind, blocking the line of sight and so on.

4. Outdoor personnel should pay attention not to avoid hail under trees, telephone poles and other places. There is danger of electric shock, try to find a strong and safe place to avoid.

5. Lightning protection measures should also be taken in hail weather.

In case of sudden hail weather during driving, try to reduce the speed as much as possible to avoid the instability of the car body caused by too fast speed and easy to be blown down by strong winds. At the same time, hail may damage the car, so try to find a safe place to park. If there is no place to hide nearby for the time being, don't speed up the departure, slow down the speed, and reduce injuries and losses.

7. In hail weather, the lights may flash. It is necessary to turn on the low beam lights and anti-fog lights of the vehicle in time to facilitate the observation of the vehicle and avoid rear-end collision. When driving on the expressway, pay attention to turning on the double flashing prompt to come to the car, and pay attention to keeping the distance between cars.

8. When driving, drive carefully when encountering stagnant water on the road, and pay attention to getting off and observing the water depth. Better take a detour. If you have to drive a water car under special circumstances, you should pay attention to driving at a low speed. If the water depth is only half that of the wheel, you can shift into first gear and move at a constant speed. When you drive into stagnant water, you must slow down and then accelerate once. Remember not to stop halfway, slam the steering wheel or shift gears, so as not to cause the vehicle to stall or damage the engine. Drive carefully, safety first.
