How to drive safely in bad weather of ice and snow?

The writer is 1976, an auto soldier, with six years' service experience. Because the army is located in the northeast, he has some practical experience in driving in low temperature snow and ice. Driving in snow and ice weather should be "one slow, two constant, three bogeys and four attentions".

"One Slow": Slow word first, safety first.

When driving in rain, snow and fog, the visibility is low, so we must control the speed, especially on the snowy road, and we must be "slow". Ordinary roads should not exceed 40 km/h, and the speed of expressways should also be reduced to the minimum limit. The minimum speed limit of Hangjinqu Expressway is 60 ~ 70 km. After the expressway freezes, high-speed traffic police usually print "vehicle speed limit data" on the information board. When you slow down on the expressway due to bad weather conditions such as rain and snow, you must turn on the "double jump" and all the lights to avoid rear-end collision.

"Two Maintains": Keep your distance and focus.

First of all, you must keep a sufficient safe distance from the vehicle in front. Under normal circumstances, the braking distance is directly proportional to the vehicle speed. In rainy and snowy weather, the adhesion between the wheel and the ground becomes smaller and the friction coefficient is almost zero. Be sure to keep a safe distance from the car in front, at least three times more than usual.

The second is to maintain concentration. In the case of heavy snow or fog, we should keep a high degree of concentration. After driving for a while, your eyes often get tired, so you can park your car in a safe place and have a rest.

"three bogeys": one bogey rushes to the direction; Second, avoid sudden braking; Third, don't refuel, don't loosen the throttle, and don't lift the clutch.

Old drivers know that the biggest taboo on icy roads is "rushing", because the consequences of rushing are either turning around or overturning.

"Sudden braking" on the ice and snow road is also a no-no, not good. If you brake with one foot, the car will swish around.

Driving on the icy road, the vehicle will still "twist its head" to deviate from the direction by slamming on the accelerator, releasing the accelerator and lifting the clutch. If you meet a car on a narrow road, you will collide with other vehicles if you don't do it well. At this time, the correct way to step on the accelerator is to "step gently and lift slowly" when learning to drive, and the clutch pedal should be lifted slowly, not all at once.

"Four Attention": Pay attention to whether the bridge deck is frozen; Pay attention to whether the air outlet road surface is frozen; Pay attention to the loss of control of vehicles following in the opposite direction or the same direction; Pay attention to whether the pavement rolled by the left and right wheels is the same.

When driving, you should also pay attention to whether the road surface crushed by the left and right wheels of the vehicle you are driving is consistent. Sometimes, the left wheel is not an icy road, and the right wheel just presses on the ice and snow (or wet land or wet mud, etc.). ). At this time, if you brake, the friction coefficient of the wheels on both sides is different, and it is easy to have an accident of "the front of the car twists to the right".

"trick": pull the foot brake at the same time.

Automobile braking principle: the foot brake is the braking wheel and the hand brake is the braking power transmission device. As mentioned earlier, the foot brake is urgent and the vehicle is easy to turn around. Then when braking on the snowy road, you can only lightly step on the brake pedal, and you can't stop it in a short distance. So while stepping on the brake pedal, pull the handbrake "halfway" (it is easy to break the control line of the handbrake if you can't pull it), then step on the footbrake and pull the handbrake again. Therefore, "staggered hands and feet, alternating braking" can play an ideal role.
