First, don't drive the inner side road of the expressway.
The most dangerous section of driving in rainy days is on the expressway, because the vehicles driving at high speed are the most serious. No matter whether the braking distance is prolonged, the probability of drowning or the threat caused by unclear vision, especially when the vehicles lose control when passing through the road with serious water accumulation at high speed, it is more likely to cause serious injuries to people and vehicles. We should avoid the problem of vehicles losing control and drowning.
In addition to slowing down to drain the tires, it is also a good idea to try not to walk in the inner lane. This is because the drainage system of any road will be set on both sides of the road. When the rain pours down, the drainage ditch in the inner lane sometimes has no time to discharge the rain, which will lead to water accumulation on the road surface, especially at the inner corner. Therefore, it is recommended to avoid the inner lane in rainy days. In heavy rain, the inner lane of expressway will be more prone to water accumulation than other lanes, and it is less likely to drift in the middle lane as far as possible.
Second, speed should be increased in deep water.
If the vehicle accidentally travels to an area with deep water, remember not to let the water overflow the height of the front bumper, so that the engine will not absorb water. In addition, it is necessary to downshift and speed up, and drive at a leisurely speed, so that the engine can pass through the deep water area without stalling.
This is because the outlet height of the exhaust pipe is relatively low and it is easy to be submerged by water. If the exhaust gas in the pipeline does not have enough exhaust pressure to be discharged from the car, the engine will stall even if it does not absorb water, which may put itself in a dangerous state.
If you accidentally drive near the water depth, you can pass as long as the water depth does not exceed the front bumper, but remember not to collect oil. But downshift, so that the exhaust gas in the exhaust pipe has enough pressure to be discharged, so that the engine will not stall.
Third, the brake system should be warmed up.
When driving for the first time on the day of going out in the morning, the temperature of the brake system is relatively low in rainy days, and there will be a lot of raindrops attached to the disk. When stepping on the brakes for the first time, it is easy to get worse because of low temperature and rain. Therefore, the author suggests that before preparing to run a red light, you can step on the brake pedal a little hard to let the temperature of the disc rise, and at the same time, it can also reduce the situation that rain adheres to the disc, especially before preparing for high speed. It is suggested that this action must be done to shorten the emergency braking distance. Of course, if you can brake with your left foot, you can hold the brake pedal slightly with your left foot when accelerating, and the preheating effect is better.
When you just go out on a rainy day, the braking force will get worse because of the rain on the plate. It is suggested that the normal operation of the brake system can be better ensured by stepping on the brake several times and raising the disc temperature under safe conditions.
Fourth, start with the second gear on the wet road.
Earlier, TV news reported that a domestic recreational vehicle started on a slippery cement ramp, and as a result, the front wheel actually slipped, and the vehicle began to slide down at the same time until it hit the toll gate. In this way, the author speculates that the owner should start from the D gear (first gear), and as a result, the front wheel will slip because of the excessive torque output at this moment, and once the tire starts to slip, it will lose its grip and make the vehicle "reverse". If there is a cliff behind a muddy slope in the mountain, what happens may have disastrous consequences. The easiest way to avoid this kind of thing is to start in second gear, and the automatic manual transmission can be put into second gear before starting. The traditional automatic transmission will also have two-speed switching to reduce the starting torque of the tire and make it difficult for the tire to slip. This is a very common practice in Snow Country. It may come in handy to learn to go to Hehuan Mountain another day.
When starting on a wet road, try to use the second gear to avoid the tire slipping and the vehicle losing control.
Fifth, the tread pattern should be high enough for the tire pressure.
The most important thing for safe driving in rainy season is the depth of tire tread pattern, which is related to the speed and ability of tire to drain water through accumulated water. If the tire is not deep enough, the drainage efficiency will naturally be poor. Once the vehicle passes through the road with deep water, the whole tire may float on the water due to insufficient drainage. At this time, the vehicle will completely lose the grip of this tire like floating on water, and even the left and right wheels will suddenly "catch the tire", which is light. Therefore, the author suggests that in order to obtain the basic tire drainage effect, the tread depth should not be less than 2mm, and vehicles with tread depth less than 1 .6mm from 20 14 65438+ 10/will fail the final inspection. For the safety of family members and other passers-by, it is better not to save tire money.
When the tire runs over the puddle, the water on the tire ground will be immediately squeezed into the drain tank by gravity. Therefore, if the tread is not deep enough and there is not enough space to get wet, the tire will float on the water and lose its grip instantly, resulting in a dangerous situation in which the left and right wheels grab the tire and even shake their tails out of control.
Sixth, remember to turn on the front and rear fog lights.
The reason why cars are equipped with front and rear fog lights is to let car owners use them in rainy and foggy weather, which can remind oncoming cars to pay attention to their position. Therefore, when driving in rainy days, you can turn on the front and rear fog lights, which can achieve better warning effect. In addition, it is suggested that if the original car is equipped with front fog lights, try not to replace the front fog light bulbs with ultra-white bulbs with high color temperature bulbs. This is because the penetration of white light is worse than that of yellow light, especially in rainy nights or foggy days. Because slightly white light is easily reflected by the same white fog, the front visual field appears white, which shortens the front visual field and affects the driving safety, while the performance of yellow light bulb is better.
Driving in rainy days can turn on the front and rear fog lights, which can get better wake-up effect. It is also recommended not to replace the front fog light bulb with an ultra-white light bulb with high color temperature, because white light can't see the road clearly in rainy days, but yellow light bulb has better penetration ability and better lighting effect in rainy and foggy days.
The seventh and fifth doors commonly use rear wipers.
Many five-door vehicles, such as hatchbacks, recreational vehicles, SUVs or trucks, are equipped with rear wipers. The reason is that when these vehicles are driving at high speed, the airflow behind the car body will be rolled up due to aerodynamics, and it is easy to roll the dirty water and dust on the road surface onto the rear windshield, so that a large amount of dirt is attached to the rear windshield, resulting in poor rear vision. This is also the reason why the rear wiper is often used.
When driving at high speed, the rear windshield of a five-door car will be attached with a lot of dirt because of the tumbling airflow, so a rear wiper will be designed for the owner, and remember to turn it on in rainy days.
Eighth, open the air conditioning glass without fogging.
In the face of wet rainy season, whether the car can keep dry and comfortable will also greatly affect the driving safety. Especially in rainy days, if there is no air conditioner blowing dehumidification on the front windshield, the inside of the glass will soon fog, which will greatly affect the driving sight. However, some people may ask that the temperature is already low in rainy days. Turn on the air conditioner and drive without a coat? If I don't tell you, many people may not know that air conditioning and heating can be turned on at the same time. This combination can produce dry warm air, which can play a role in dehumidification and mildew prevention in an environment with extremely high relative humidity. If the car has a constant temperature air conditioner, the setting is quite simple. Just press the auto button and set the temperature at about 22 degrees, and the car will automatically blow out a dry and moderate airflow.
On rainy days, the air conditioner must be turned on in the car to avoid fogging the glass, but it doesn't mean that cold and warm air can't work at the same time. As long as the A/C function is turned on and the temperature is adjusted to a warmer temperature, such as 24 ~ 25 degrees, the air sent out will be dry warm air.
Ninth, waterproof and mildewproof are healthier.
On rainy days, the sludge and bacteria under your feet are more likely to enter the car, and then penetrate into the carpet with sewage, and then slowly invade the body through the cold air circulating indoors. Therefore, I suggest that you replace the original foot pad on the fluffy surface with a plastic material with waterproof effect. However, in order to avoid the influence of the sliding of the foot pad on the operation of the accelerator/brake pedal, it is necessary to choose a three-dimensional foot pad with a fixed function to improve driving safety. In addition, in rainy days, because the windows are closed for a long time, the dust, suspended particles and bacteria all over the car are constantly circulating in the car, looking for opportunities to invade the human body. It is good for adults with strong resistance. Once there are children in the car, their health may be threatened. Therefore, if the air conditioning filter can be replaced regularly, it will be helpful to maintain the air quality in the car.
There are many three-dimensional waterproof foot pads on the market, which can effectively prevent the sewage from the soles of the feet or the rain from the umbrella from infiltrating into the carpet to produce musty smell, and the special design of the car does not have to worry about getting stuck on the accelerator/brake pedal.
Many modern cars are equipped with air conditioning filters, which are hidden behind glove boxes. In order to meet the coming rainy season and summer, you may wish to check the condition of air conditioning filter by DIY yourself, sometimes the dirty situation will surprise you.
Tenth, wear sunglasses.
Driving in rainy days sometimes leads to the problem of unclear sight ahead because of the scattering effect of rain. At this time, if the light permits, you may wish to wear sunglasses, which can improve the foggy situation ahead and make the road ahead clearer through a slight polarization effect.
