4. Precautions for driving in typhoon days

1. Use lights correctly. In the bad weather of typhoon and heavy rainfall, the visibility is very low, so it is necessary to keep the following distance of at least 5 meters, turn on the low beam, position light, front and rear taillights and double flashing, and the speed should not exceed 4 km/h. When the visibility is less than 5 meters, you should find a safe place to stop as soon as possible.

2. Don't open the window, and pay attention to the crosswind. The typhoon is too strong, so opening the window will seriously affect the driving stability. When passing by bridges, tunnels, rivers and other roads, we should guard against the influence of crosswind on the driving route. In case of cross wind, you should slightly tap the steering wheel in the direction of vehicle deviation to correct the direction. Do not slam on the brakes or the steering wheel.

3. Keep driving at a low speed. Typhoons are basically accompanied by heavy rainfall, the road surface is slippery, and the braking distance is prolonged. Therefore, it is necessary to keep driving at a low speed and use throttle and gear to control the speed. Don't drive too fast, so as to avoid the vehicle deviation caused by "water sliding".

4. Choose a safe place for parking. It is recommended to park in an empty parking lot and try to avoid parking under billboards, trees, street lamps, telephone poles, flower pots, air conditioners, etc. It is also necessary to avoid parking in low-lying sections and parking spaces to avoid flooding cars.

5. How to prevent typhoon from accompanying rainstorm

1. Try not to go out during rainstorm, pay attention to the weather forecast through radio, television, mobile phone or internet in time, and grasp the latest news of rainstorm.

2, check the circuit, fire and other facilities, when the accumulated water overflows into the room, immediately cut off the power supply to prevent the accumulated water from being charged and hurting people.

3. Cover the articles to be aired in the open air in advance, and pack up valuables at home and put them in a high place.

4. People living in dilapidated houses or low-lying houses should be moved to safe places in time to prevent the collapse of old houses from injuring people. Residents should adjust measures to local conditions, and place flashing boards, sandbags or mounds at their doorways.

5. When the water under the road or overpass is too deep, the driver should try to bypass and avoid forced passage; When the car stalls in low-lying water, people should never wait in the car, but get off and wait for rescue at a high place.

6. When traveling in mountainous areas, you should pay attention to prevent mountain torrents. When the upstream water suddenly becomes turbid and the water level rises rapidly, you should pay special attention and move to a safe area in time.
