We are currently in the peak period of the Spring Festival travel rush. Rain, snow and freezing weather have a great impact on traffic. Please keep an eye on the weather forecast and adjust your itinerary in time. The central and eastern regions will remain cold for a while after the temperature drops. Please remember to add clothes to keep warm. The following are travel safety tips and warmth-keeping guidelines.

【Travel safety tips】

1. How to drive more safely on icy and snowy roads?

In cold, rainy and snowy weather, people who need to drive should remember to "reduce speed, control distance, and turn on tail lights", drive carefully and travel safely. When encountering traffic control, you must obey the instructions of the on-duty traffic police and queue up in turn.

1. Slow-moving vehicles

Reduce your speed and drive at a constant speed as indicated by the traffic department, which is generally 20-30 km/h.

The vehicle speed should be stable while driving, and sudden acceleration should be avoided. When accelerating or decelerating, the accelerator should be pressed or released slowly to prevent the drive wheels from slipping due to sudden acceleration or deceleration.

2. Keep safe distance between vehicles

Increase the distance between vehicles, which should be 2 to 3 times the normal distance, to leave enough space for longer braking distance.

Drive along the track of the vehicle in front, generally do not overtake, keep the engine speed even, and do not accelerate, decelerate or brake suddenly.

3. Slow down first, then turn

When driving on a curve or slope, you should lightly press the brake to slow down in advance.

When you need to turn, slow down first, increase the turning radius appropriately and steer gently to avoid skidding due to sudden increase in front wheel resistance caused by turning too hard.

When braking, brake lightly, and then increase the braking force after the speed gradually decreases. At the same time, use the braking force of the engine to brake. Do not brake suddenly or hard to avoid the vehicle skidding.

4. Emergency response methods for emergencies

When you encounter skidding or drifting caused by over-braking or accelerating too quickly, you should immediately release the brake pedal and use continuous braking instead of turning the steering wheel suddenly. Turning the steering wheel to change the skidding state will not correct the situation and may even backfire.

When entering a curve too fast and the vehicle starts to skid, first release the accelerator pedal, then slightly correct the direction, and keep adjusting between steering and correcting, but not too much, and do not exceed the normal driving position of the wheels. If necessary, lightly brake to slow down and correct the direction.

When you encounter an over-steer situation that causes the rear end of the car to swing forward and tend to turn around, you should also release the accelerator first, and gently but quickly reverse the steering wheel. You must return to the center line and use the brakes to reduce speed if necessary.

2. Make these preparations before driving on the road

When driving in cold, rainy or snowy weather, you need to make adequate preparations before hitting the road.

1. Check the vehicle condition before departure

Low temperatures can easily cause vehicle failures. Before departure, you should carefully check the vehicle's power system, braking system, lighting system and tire conditions to avoid vehicle breakdowns on the highway and rear-end collisions. During the peak travel period of the Spring Festival, gas stations and charging piles in highway service areas are all in saturated operation. Traveling vehicles should be fully refueled and fully charged in advance to avoid breakdowns due to insufficient battery life. Once a traffic accident or vehicle failure occurs and the vehicle cannot move, the people on the vehicle must evacuate to the outside of the highway guardrail in a timely manner and call the police for help in a timely manner.

When driving in heavy snow, you should clear the snow off the car body and windows and try to maintain a good driving vision. When driving in bad weather, you should turn on the low beam headlights, clearance lights, and front and rear position lights. When visibility is less than 100 meters, you should also turn on the hazard warning flashers. The lights not only illuminate the way home, but also make you more conspicuous.

2. Prepare the necessary items

When driving in cold, rainy, or snowy weather, you can carry anti-skid chains, hardwood blocks, waste cardboard boxes, and other items with you in case of emergency situations such as tire slippage on icy and snowy roads. Before departure, you should replace snow tires or install anti-skid chains in advance. Before departure, check whether there is a triangular warning sign on the car and whether the warning sign is intact. In addition, in order to cope with bad weather at night and in rain and snow, you need to always have flashlights and reflective vests in your car.

Classification and usage scenarios of anti-skid chains

At present, the mainstream anti-skid chains on the market are divided into the following 4 types:

Iron anti-skid chains: mainly used on large vehicles, they are noisy, difficult to install and remove, and cause serious wear on tires;

Tendon anti-skid chain: The anti-skid effect is average and not durable, suitable for short-term use on ordinary ice and snow roads;

Rubber anti-skid chain: It has the advantages of low temperature resistance, wear resistance, good elasticity, strong friction and good tensile resistance, and is suitable for long-term use in family cars;

Wire rope anti-skid chain: The structure is relatively simple, easy to install, and has a long service life. The disadvantage is that it causes greater wear on the tire and is relatively expensive.

【Guide to keeping warm】

The elderly, pregnant women, infants and young children, patients with chronic diseases such as cardiovascular and cerebrovascular diseases, respiratory diseases, and people who work or engage in activities outdoors for a long time are easily affected by cold weather and need to pay special attention to health risks.

Among them, elderly patients with chronic diseases have reduced metabolic function and relatively less heat production, and their body temperature regulation system has difficulty adapting to changes in external temperature; being in a cold environment for a long time can cause frostbite, which can easily have adverse effects on pregnant women and fetuses.

The "Keep Warm and Prevent Cold" health tips issued by the National Health Commission clearly state that sensitive groups should focus on the following points: add cotton-padded clothes and trousers to keep warm, and pay special attention to keeping the head, chest, neck and limbs warm; try to reduce going out, and take warming measures when you must go out; pay attention to rest and avoid excessive fatigue; increase physical exercise moderately to enhance resistance; families using coal stoves for heating should beware of gas poisoning; pay attention to weather forecasts and cold wave news so that necessary protective measures can be taken in time.

If the human body is exposed to cold for a long time and shows signs such as chills, collapse, memory loss, and drowsiness, this may be "hypothermia". Experts from the Environmental Institute of the Chinese Center for Disease Control and Prevention said that when encountering these signs, the body temperature should be measured in time, and if the body temperature is below 35 degrees Celsius, medical treatment should be sought immediately. When medical treatment cannot be obtained immediately, the person with hypothermia should be taken to a warm room or residence as soon as possible; wet clothes should be taken off in time; hot drinks should be taken, and relevant measures should be taken to warm the core area of ​​the body. After the situation is relieved, medical treatment should be sought as soon as possible.
