No frills. Why on a slippery road it is necessary to turn off the four-wheel drive?
The weather brings surprise after surprise. Snowfalls are followed by "ice rains" - and again snowfalls. And if the elements caught on the way, then the driver has to resort to special methods of driving.
Drift on the track
The worst thing on an intercity highway is “freezing rain”. If the driver sees how drops of water began to pour on the windshield, and the thermometer at that time shows minus 5 degrees below zero, then expect problems. It is best to cancel the trip, park the car and return home. However, for those who are already on the road, difficult hours are coming. The road is covered with a slippery crust of ice with a minimum coefficient of adhesion.

First of all, when a "freezing rain" occurs, it is necessary to slow down and check the adhesion of the tires to the road surface.
To do this, briefly apply the brake and evaluate the deceleration. If the ABS is activated, and the car does not slow down, then it is worth gathering your will into a fist, not making sudden movements and smoothly shifting into a lower gear. When the brakes are ineffective, you will need to brake with the motor.
Your best bet is to shift into straight third gear and drive at a higher RPM so that there is always traction on the wheels to pull the car forward without yaw.
When the gas is released, the speed will be reset due to the internal resistance of the power unit and transmission. True, this rule is true only for front-wheel drive cars, which are now the vast majority. On rear-wheel drive vehicles on slippery roads, on the contrary, it is better to shift into higher gear to avoid slipping of the drive wheels, which almost always leads to destabilization and steering of the stern.
Connected out of place

Now the most popular type of all-wheel drive is plug-in. On all-wheel drive vehicles with a connected rear axle, it is best to turn off the rear-wheel drive. The fact is that on a country road with heavy ice, yaws are very dangerous. Therefore, any thrust on the rear axle can lead to steering of the stern, especially when this thrust appears unexpectedly for the driver.

Destabilization occurs in this way: during the slipping of the front wheels, the moment is thrown back, and the car goes sideways a little, which makes the driver nervous.
This steering effect is very fond of drifters, who, with skillful use of gas, can make an all-wheel drive car famously throw the body sideways and rotate in a circle. However, on an intercity highway, such maneuvers are risky and unacceptable, especially for an unprepared driver. Therefore, any traction on the rear axle when the front wheels slip can cause destabilization.
It is especially unpleasant if the car is moving in a slippery rut covered with a crust of ice. In this case, the skidding of the rear axle can occur at any time.

There is no need to panic here. The main thing to remember is that the car goes exactly where its wheels are directed.

If the car went the wrong way and began to slide sideways, then you can not twist the steering wheel too much. You can release the gas and try to direct the car into your lane with light steering corrections. She will react with a second delay. If you overdo it and turn the steering wheel hard, and even give it a lot of gas, you can end up in a ditch.
In general, if an all-wheel drive crossover has a function to turn off all-wheel drive, then it can be used on a slippery road. If it is not there and the all-wheel drive system is set to automatically redistribute the moment, then in this case it is better not to get carried away with gas and try to use the accelerator in a dosed way so as not to cause stern steering.
In addition, all-wheel drive crossovers with plug-in all-wheel drive systems, which also require special control methods on slippery roads, are now widely used.
