What are the precautions for driving in rainy days?

According to the international driving safety survey, the traffic accident rate of driving in rainy days is about 5 times higher than usual. Drivers must be vigilant when driving in rainy days.

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

Second, if the wading depth exceeds the engine compartment cover, it is recommended not to drive again and stop immediately. Otherwise, "valve top" is easy to appear. If you turn off the fire when crossing the water, 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 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.

Sixth, it is best to change 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, driving in the night rain, the raindrops that have not been scraped clean will produce all kinds of reflected light under the light, which will make the front view extremely blurred and easily lead to accidents.

Seventh, paint some wax on the car glass. If the glass cleaner contains some wax, a layer of wax film can be formed on the glass surface after use, and the wiper will sweep the water thoroughly to protect the glass.

Eight, regularly check whether the waterproof slot at the front windshield is clear. Avoid the water in the engine caused by water accumulation in rainy days, and prevent the on-board computer from being short-circuited. The computer of FAW series cars is under the waterproof slot.

Nine, 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.

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

Eleven, night rain, cloudy driving, turn on the night driving lights in time. The visibility of driving at night is poor, so in order to prevent rear-end collision, the night driving lights 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.

Twelve, pay attention to the drainage system when adding skylight. It is a troublesome thing that the skylight leaks rain, but the drainage system of the skylight is sealed on the roof, so it is usually not easy to check. Generally, the drain pipe of the skylight will be thrown to the C-pillar position, and sometimes it will be thrown to the B-pillar position. When installing the skylight, we must pay attention to the regularity and smoothness of the drainage system installation, otherwise we can only enjoy the "rainy" moment in rainy days.

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

14. Don't lower the tire pressure when driving in rainy days. According to experience, some people let out some air in the tires before driving in rainy days, and put the tires flat to increase the contact surface, increase friction and prevent the tires from slipping. But this practice 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 to stop the car. However, the contact area of the tire becomes larger, the pressure on the ground unit area decreases, the braking force weakens, and the rainwater between the tire and the ground cannot be discharged quickly, resulting in a longer sliding distance.

Fifteen, the sand on the road is easy to slip. When it begins to rain, especially in Mao Mao, the dust and sand on the road surface have not been thoroughly washed, and the sand that absorbs water becomes clay, which is very easy to slip. Pay attention when driving. When it rains for a while and the sand is completely washed away, the road conditions will be better.

Sixteen, for the unknown depth of the road, get off patrol or wait. The water depth exceeds the exhaust pipe, which is easy to cause car damage and death; The water depth exceeds the bumper, so 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, but haste makes waste.

Seventeen, for the window fogging, you can turn on the cold air and choose the gear that blows the glass directly. Starting the external circulation will cause the filter element to absorb moisture and produce air conditioning odor.

18. Products such as' Rain Enemy' sold in the market can prevent the outer glass from fogging, but the effect of' Washing Spirit' is better. Wipe the rearview mirror and triangular window evenly with paper towels before it rains, so you don't have to worry about fogging. This method is one-off and should be applied continuously after rain. You'd better find a container to put some in the car for later use.

Nineteen, even after wading, you should step on the brakes and dry the accumulated water in the ventilation tray, otherwise the tray will rust or reduce the braking ability because of water ingress.
