In this weather, the rain turned into a snowstorm.

Since the weekend, snowflakes have floated in many places in Henan, especially in Anyang and other places in the north, with varying degrees of snowfall. With the arrival of a strong cold air after New Year's Day, there will be an obvious continuous rain and snow weather in our province this week.

however

Just tonight

Light snow, snow, blizzard, sleet

Will come in droves!

Today during the day, the whole province is cloudy, with sleet or small to medium snow in the west and north; There is little to moderate rain in other areas. From today's night to tomorrow's day (from the night of the 6 th to the day of the 7 th), the whole province is cloudy, with moderate to heavy snow in the central and northern parts and partial snowstorms; Other areas changed from moderate rain to moderate sleet. Affected by cold air, the northerly winds in the province are 4-5.

Specifically,

This is the case in Zhengzhou these two days.

Before driving

Clean up the car and warm up early. Don't rush on the road yet.

After it snows, vehicles parked outdoors need to pay attention. Before getting on the bus, if it is covered with snow and ice, the first thing to do is to clear the snow from the front and rear windshields, rearview mirrors and surrounding windows. If there is no special snow removal tool, you can use hard cards such as bank cards and ID cards to scrape the snow. Never scrape the snow with a wiper. Forcibly starting the frozen wiper can easily burn out the motor.

In order to avoid the "single slip" of parked vehicles, when parking, you should avoid places with large slopes and no signs of melting in cold snow and ice, and be careful not to get too close to vehicles such as buildings to prevent side slip. After parking, you can plug anti-skid obstacles such as stones on the lower side of the tire. In addition, the hand brake should be used with caution when parking in rain and snow, because some drum brake models will get water in the braking system after driving in the snow. Once frozen, the next day's hard hand braking action will cause damage to the parts in these two positions.

Check the tire pressure in time. If the tire pressure is too low, the braking distance will become longer and the tire will be damaged prematurely. The gas in the tire expands with heat and contracts with cold, resulting in a drop in air pressure. If the air pressure is found to be too low, it should be replenished to the specified tire pressure in time before going on the road.

drive

It is important to master the skills of driving in the snow.

Emergency braking is the most taboo for wet roads in snowy days, because once emergency braking is taken, the tires will inevitably slip out of control and cause danger. Therefore, when driving, you should first keep a good distance from the car in front, which is larger than usual (rest assured, few people will force the merger in this weather), and pay attention to the situation ahead. When the front side needs to slow down, take necessary measures according to the actual situation and speed. If the speed is not very fast, you can take intermittent braking. If the vehicle speed is fast, you must quickly change the gear to a low gear (for example, the fourth gear is quickly reduced to the third gear, and the third gear is reduced to the second gear), so that after the vehicle speed is reduced, you can take intermittent braking until the vehicle stops.

Secondly, when starting in the snow, don't give a big throttle, so the tires will slip and cause the direction to get out of control. The correct method should be to lightly step on the accelerator to keep it steady, and then slowly feed the oil after the car starts. Don't panic when the slope rises. At this time, the more fuel you add to the car, the easier it is to slip back. First of all, calm down, hold the brake and gently give the throttle. When the car has a starting trend, release the handbrake and drive the car smoothly. Don't drive more than 40 kilometers in urban areas and 60 kilometers on expressways in snowy days.

Take the elevated track and control the distance at high speed.

The traffic police reminded the majority of car owners to get on the viaduct as little as possible in the early morning and late at night. "According to previous years' experience, citizens should try not to drive in the morning and at night in rainy and snowy days, especially on viaducts."

Because the bridge itself is ungrounded, when other roads are not frozen, the bridge deck will always freeze first, especially in the early hours of the night. If the driver is not careful, it is easy to brake improperly, causing the vehicle to sideslip and collide. The traffic police said that sudden acceleration, sharp turns and trailing driving are all taboos for driving in rainy and snowy days. In the early morning and late night of rainy and snowy days, drivers should drive smoothly on the viaduct, reducing the number of parallel lines or overtaking. When going up and down the elevated turn, you should slow down as early as possible, increase the turning radius appropriately, and never slam the direction, otherwise it is very easy to slip.

The reporter also learned from the Henan high-speed traffic police: "It is very difficult to drive in rainy and snowy days. In order to cope with the upcoming snowfall, we must expand the distance. " Most traffic accidents in ice and snow days are caused by improper handling by drivers. In addition to slowing down, you should keep enough distance from the car in front. At ordinary times, the safe distance between cars is150-200m, and it is best to keep it at 300-400m. Secondly, in order to prevent the vehicle from skidding, rolling over and losing control of direction, remember not to brake suddenly when driving on frozen roads, and don't swerve and turn sharply, especially when driving at high speed. When parking is needed, measures should be taken in advance to slow down the speed by loosening the throttle and downshifting.

avert a misconception

Is ESP useful or not? Can four-wheel drive really sit back and relax?

ESP is the electronic stability system of car body. When a vehicle passes through a low-friction road, the direction and speed of the vehicle can't be controlled by the driver because of the tire slipping. ESP stabilization system can help the driver to regain control of the vehicle by braking the non-slipping wheels, thus ensuring driving safety. However, there are two situations that need to close ESP: one is the vehicle with snow chains, and the ESP system can be closed; The other is to turn off the ESP system when the wheels slip and get stuck, so that the vehicle can get out of trouble.

Some car owners think that my car is a four-wheel drive, which will perform better in ice and snow conditions, but the resulting false sense of security sometimes backfires.

The four-wheel drive system will apply a specific torque to each tire, which will make it have greater traction and make the car move smoothly on the snowy road. However, this does not mean that people can drive at a fast speed on the snowy road and stop in time. Because the friction of the wheels is constant, the four-wheel drive may not stop if it is too fast.

In order to prevent vehicles from stopping, two methods are the most effective, namely, controlling the speed and keeping the distance between vehicles. If you want to drive in snowy days, please extend the distance to twice the daily distance, and to be safe, you can increase it to three times. Leave yourself at least six seconds to brake, which is equivalent to the distance of four cars at a speed of 20 km/h. In addition, you should pay attention to the signal lights, stop signs and corners in advance so as to have enough time to brake or turn.

Too fast speed will not only increase the probability of accidents, but also reduce the reaction and judgment time when the vehicle is out of control. It takes 4 to 10 times longer to brake on icy or snowy roads than on dry asphalt roads. This requires drivers to leave enough braking distance and time for themselves, so it is very important to control the speed. If a collision is inevitable during driving, the cost of choosing a side collision will be less.
