What are the precautions for safe driving in rainy days?

The accident rate of driving in rainy days is about 5 times higher than usual. Drivers must be vigilant when driving in rainy days. Let's talk about the precautions for driving in rainy days.

First of all, if the wading depth exceeds the front bumper, you should be vigilant when driving. If it is found that the air filter is wet or flooded during the inspection, it should be stopped as soon as possible to prevent the engine from flooding.

Second, if the wading depth exceeds the hood, it is recommended not to drive again and turn off the engine immediately. Otherwise, "valve top" is easy to appear. If the engine is turned off while the water is flowing, don't try to start it again.

Third, don't cross ditches and puddles at high speed. This will cause splash, increase the actual wading depth, and easily lead to engine water intake.

Fourth, don't dodge around when you see stagnant water. Flash when you see water, or brake immediately to slow down, which is a common problem of ordinary people. In fact, both methods are very dangerous. On the contrary, it is easy for the drivers behind to misunderstand, causing accidents of flashing left and avoiding right.

5. Keep a safe enough distance. Because the braking distance of a car will be longer in rainy days, you should keep a safe distance when driving.

6. It is best to replace the wiper once a year. If the water sweeping ability of the wiper decreases, it is difficult to observe the road conditions when driving in rainy days. Especially when driving at high speed, the wiper blade floats up and the water sweeping ability is worse. In addition, when driving in the rain at night, the raindrops that have not been scraped will produce all kinds of reflected light under the light, which will make the front view extremely blurred and easily lead to accidents.

7. Put some wax on the car glass. If the glass cleaner contains some wax, it will form a wax film on the glass surface after use, and the wiper can completely sweep the water and protect the glass.

8. Observe more, and observe more when merging. The exterior rearview mirrors of many cars have no automatic heating function, and the raindrops accumulated on the exterior rearview mirrors in rainy days are easy to cause blind spots for drivers. In addition to cleaning the rearview mirror in time, drivers should pay more attention.

Nine, when it is raining and cloudy at night, turn on the night driving lights in time. Visibility is poor when driving at night. In order to prevent rear-end collision, the driving lights at night should be turned on in time. In addition, on cloudy days, rainy days with heavy rain and fog and poor visibility, the running lights at night should also be turned on in time.

Ten, pay attention to the drainage system when installing the skylight. The skylight leaks rain and disturbs people, but the drainage system of the skylight is sealed on the roof, so it is generally not easy to check. The drain pipe of the skylight will generally swing to the position of C-pillar, and sometimes it will be placed at the position of B-pillar. When installing the skylight, we must pay attention to the regularity and smoothness of the drainage system installation, otherwise it will only be rainy.

1 1. Don't turn off the engine when parking in rainy days. Although the hood is rain-proof, it is inevitable that there will be an empty gap, and the water splashed on the ground will wet the ignition system, resulting in the engine not being started after the rain.

12. Don't lower the tire pressure when driving in rainy days. According to experience, some people will release some air in the tires before driving in rainy days, which will flatten the tires, thus increasing the contact surface, increasing friction and preventing the tires from slipping. But this is not desirable. There are very limited methods to reduce the gas in the tire to increase the friction coefficient. When the car brakes in the rain, the most important thing is to have enough pressure to drain the rain between the tire and the road, so that the car can stop. However, with the increase of the contact area of the tire, the pressure per unit area of the ground drops and the braking force weakens, which leads to the rain water between the tire and the ground can not be discharged quickly, resulting in a longer sliding distance.

Thirteen, road sand is easier to slip. When it begins to rain, especially just after the rain in Mao Mao, the dust and sand on the road surface have not been completely washed away, and the sand that absorbs moisture has turned into soil, which is very easy to skid the tires. Pay attention when driving. In the next period of rain, the sand will be completely washed away and the road conditions will be better.

14. For the section with unknown water depth, get off and check or wait. If the water depth exceeds the exhaust pipe, it is easy to damage the car; When the water depth exceeds the bumper, it is easy to get water from the air filter and air inlet. For the road section with unknown water depth, it is best to get off the bus to patrol or wait, so as not to cause the engine to enter the water and stall.

15. Regularly check whether the windshield waterproof trough drains smoothly. Avoid the water in the engine caused by water accumulation in rainy days, and prevent the on-board computer from being short-circuited. The computers of FAW-Volkswagen series are under the waterproof cabinet.

Sixteen, regularly check the tire wear, timely replacement. Excessive tire wear is likely to form a water film between the tread and the water surface, leading to vehicle deviation, tail flick and longer braking distance.
