Driving on the highway, in case of emergencies or traffic accidents, please remember that "the car pulls over, the person evacuates, that is, the alarm".
Snow day safe driving common sense you should know!
Cold air brings cooling and snowfall
Snowfall poses a risk to driving
Attention!
Let's see how to drive safely on snow and ice roads
What is the snow and ice pavement like?
Snowy, snowy pavement
It usually occurs when it first snows or where it is not cleared in time. The snow on the road area is generally looser, and the vehicle has greater driving resistance and emits a loud noise when driving.
Snow compacts the pavement
The snow on the road area was not cleared, and pedestrian vehicles were repeatedly crushed. The snow will only be compacted, the road surface will become more and more slippery, the vehicle will slip from a fast start, and the braking distance will increase significantly. Such roads are easy to appear on alleys, suburban non-main roads, country roads and other roads. Driving on these roads, do not hit the direction with the big foot throttle, stabilize the direction and throttle or drive safely.
The snow turns into an icy pavement
After a long period of crushing, melting and then freezing, the snow becomes hard ice and is firmly fixed to the ground. Due to the long-term rolling of the vehicle, the hard ice surface is usually densely uneven, and the friction coefficient of the road surface is seriously reduced. Vehicles are difficult to start and brake, need to slow down and slow down, and often appear on urban streets.
Ice pavement
This type of ice section is usually high in the daytime temperature rain or sleet, and then in the evening the temperature is low, the water on the road surface will freeze, usually in the winter and near the spring. When encountering such road conditions, it is recommended to reduce driving trips.
Snow and ice driving skills
Start
When starting on the ice and snow road, you should slowly release the brakes or release the clutch, let the vehicle move slowly and then lightly press the accelerator. Do not be too big foot oil at the same time, the wheels are slippery, and it is easy to slip sideways.
When starting, manual 2-speed can be used to start, reducing the power output of the engine and suppressing the phenomenon of wheel slippage.
Some vehicles have a snow mode, making it easier for the driver to get started. Snow mode limits engine power output, dulls the throttle, and gets off to a smooth start.
Speed
Accelerate the ice and snow road to slowly step on the accelerator, so that the speed can be slowly softened. Can not be vigorously accelerated, easy to lead to driving force slippage, high-speed slippage is more dangerous. If the vehicle is found to have slippage or left and right swing during the acceleration process, the throttle should be released in time to grasp the steering wheel, so that the vehicle can slow down on its own and cannot brake vigorously.
brake
Now the vehicle is basically equipped with ABS anti-lock braking system, even if you vigorously step on the brake wheels will not be seriously locked, ABS will keep the slip rate around 20%. At the same time, the vehicle is equipped with an EBD braking force distribution system, which can make the vehicle's brakes make appropriate distribution. Therefore, when braking on ice and snow roads, the ABS can be pressed vigorously, and the ABS works immediately to achieve the maximum braking effect.
In addition, the use of engine downshift braking is also a good choice. When deceleration is required, actively downshift the gearbox so that the deceleration effect is better and very smooth.
Drive on dry roads as much as possible
There is less snow and ice on dry roads, and the wheels are less prone to sudden slippage. When driving on the highway, do not put one side of the wheel on the dry road, the other side on the ice and snow road, resulting in different friction coefficients of the two sides of the wheel friction, oil or braking is easy to slip and produce danger.
Reminder Snow high-speed driving to remember these points!!!
Snowy days will bring great inconvenience and safety hazards to people who travel at high speed. Therefore, the traffic police Remind the majority of drivers and friends that driving on the highway on snow days must pay attention to the following aspects:
1. Pay attention to traffic conditions and lights
Before getting on the highway, you should first understand the weather conditions and the traffic situation of the highway. After getting on the highway, pay attention to the prompts of the variable information board on the road surface, pay attention to the lights, such as turning on the fog lights, low beam lights to help the driver look at the situation ahead, turn on the contour lights and front and rear position lights to indicate the existence of their vehicles.
2. Pay attention to speed and distance
According to experts, the same speed of 90 kilometers per hour, the dry road brake distance needs more than 30 meters, and the ice and snow road brake distance needs more than 150 meters. Therefore, driving on ice and snow roads should reduce the speed and maintain a safe distance from the car in front. When there is a slippage phenomenon on the ice, do not brake sharply, do not hit the direction, reduce the speed and brake at the same time, so that the car slowly stops.
3. Wear appropriate colored glasses
Walking on the highway on snowy days, there are often dazzling situations, wear appropriate colored glasses, pay attention to appropriate rest, can prevent glare, but also can prevent eye fatigue.
4. Correctly remove the fog in the front windshield
Ice and snow and other bad weather, the temperature difference between the inside and outside of the vehicle is large, when the fog appears on the front windshield, do not take out the cotton cloth, towel while driving while wiping the fog on the glass, because - a small action may lead to a big disaster. The air conditioner in the car should be used to adjust the temperature in the car to eliminate fog on the windshield.
5. Slow down in traffic jams
When the traffic jam on the accident section is serious, slow down, increase the distance, drive in order, do not arbitrarily change lanes to overtake and drive on the shoulders of hard roads.
Driving on snowy days in winter is prone to accidents, and car owners need to drive cautiously.
Weinan public security traffic police tips
Ice and snow road driving, whether it is accelerated braking or turning, one word: slow! Do a good job of prejudgment and reduce large amounts of action. It is not so much a test of the skills of the driver on the ice and snow road, but also the test of the driver's driving mentality. Maintaining a calm attitude can greatly reduce the occurrence of accidents.
