What should we pay attention to on expressways and national highways?

1. Check the vehicle carefully before getting on the expressway:

First, check the fuel quantity. Because the gas station on the expressway is far away (generally 30-50km, and there may be only one gas station in some sections around 100km), the gas station may run out of oil temporarily, so pay attention to the remaining fuel when driving and refuel in advance. In addition, when the car is driving at a high speed above 100 km/h, the fuel consumption is more than expected. The economic speed of a general motor vehicle is 80- 100 km/h, for example, a car with an economic fuel consumption of 8 liters per 100 km /h may exceed 102 liters when driving at 120 km/h, and the fuel consumption may increase greatly. Therefore, when driving at high speed, the fuel should be fully prepared.

Second, check the tire pressure. When a car is running, the tire will compress and expand, which is called tire deformation, especially when the tire pressure is low and the speed is high. At this time, the abnormal high temperature inside the tire will cause the rubber layer to separate from the covering layer, or the rubber on the outer surface of the tire will break and fly away, resulting in tire puncture and vehicle accidents. So before driving at high speed, the tire pressure is higher than usual.

Third, check the braking effect. The braking effect of automobile plays an important role in driving safety. When driving on the expressway, we should pay more attention to the braking effect. Before you leave, you should check the braking effect at low speed. If there is any abnormality, it must be repaired, otherwise it is very likely to cause a major accident.

In addition, the inspection of engine oil, coolant, fan belt, steering, transmission, lights, signals and other parts can not be ignored.

We can get on the expressway after the inspection. At this time, we should also pay attention to the following driving tips:

First, enter the driveway correctly. When vehicles enter the expressway from the ramp entrance, they must increase their speed in the acceleration lane and turn on the left turn signal. Under the condition of not affecting the normal driving of vehicles in the lane, enter the lane from the acceleration lane, and then turn off the turn signal.

Second, keep a safe distance. When the vehicle is driving at high speed, the rear vehicle in the same lane must keep a sufficient safe distance from the front vehicle. The experience is that the safe distance is approximately equal to the vehicle speed. When the vehicle speed is 100km/h, the safety distance is 100m, and when the vehicle speed is 70 km/h, the safety distance is 70 m. In case of bad weather such as rain, snow and fog, it is necessary to increase the driving clearance and reduce the vehicle speed appropriately.

Third, be careful to overtake. When overtaking, you should first observe the state of the front and rear cars and turn on the left turn signal at the same time. After confirming safety, slowly turn the steering wheel to the left to let the vehicle enter the overtaking lane smoothly. Turn on the right turn signal after overtaking the overtaken vehicle. After all the overtaking vehicles enter the rearview mirror, operate the steering wheel smoothly, enter the right lane and turn off the turn signal. It is forbidden to make sharp turns when overtaking.

Fourth, use the brakes correctly. It is very dangerous to use emergency braking when driving on the expressway, because with the increase of vehicle speed, the adhesion ability of tires to the road surface decreases, and the probability of braking deviation and sideslip increases, making it difficult for cars to control their direction. At the same time, if it is too late for the following vehicle to take measures, a multi-vehicle collision will occur. When braking while driving, first release the accelerator pedal, and then lightly step on the brake pedal several times in a short stroke. In this way, the brake light can flash quickly, which is beneficial to attract the attention of the following car.

Matters needing attention in national highway:

1, when there is no car, try to drive to the center line and see how you feel sitting in the center line, so that there is more room for manoeuvre on both sides. When following a car, if the car in front is a local agricultural vehicle or a line bus, be careful near the village. The car in front may stop at any time to get on and off passengers. Driving too slowly is not necessarily a good thing when moving forward normally. Try not to slow down, lest the heavy truck overtake you. As soon as they see your crew cut, they will probably run over you. The only danger is you. China Merchants Bank should also try to avoid those operations that are overloaded and have poor conditions, so as to avoid trouble.

When passing by, keep your own lane and don't get too close to the shoulder. The closer you get to your shoulder, the more the other person will come over, and you will suffer. You can slow down and downshift first, and you can accelerate at the moment of the wrong car. When you meet at night, you should not only slow down, but also turn into a low beam, so that you can see the road ahead by flashing high beam.

3. Remember to turn on the headlights when overtaking, honk the horn as short as possible, so it will sound friendly, and then flash the headlights to remind the driver in front (don't flash around, it's annoying). On the way to overtaking, you can remind the other side of the car by flashing high beam. You don't have to honk the horn, so others can't hear you. In the same way, this method is also used to prompt when the oncoming vehicle forcibly overtakes.

Generally, novices are a little tied when driving, especially afraid of seeing red. So it is also a way to buy yourself one or two lucky mascots and put them in the car. Although there is no guarantee that this method will be effective, we can't categorically deny that it is superstition, because it is the crystallization of China's culture for thousands of years. For example, opening a car hanger is a good choice, but you can't just buy it. Each constellation has a different car hook. It belongs to rat, ox, tiger, auspicious dragon, dragon, chicken, unicorn, meditation and wisdom gourd. The specific auspicious principle can be searched by Baidu, so I won't describe it in detail here.

When you meet a village, you must slow down. The villagers have no concept of traffic rules. When the road is higher than the farmland on both sides, pay attention to whether there are traces of turning out from both sides in front. Because rural tractors, when they are fully loaded, they all get on the high-speed by impulse and enter the high-speed from both sides, which is faster. In many cases, they occupy the whole road without turning a corner.

6. When driving at night, don't blindly use the high beam, which will reduce observation and combine far and near. If you can't see the road clearly with other lights, stop immediately and look at it later. It's best to find local vehicles to follow. People are familiar with it, so it's much more comfortable to follow the taillights. Try not to follow the car with the high beam on. The car ahead is very uncomfortable. When driving at night, you should observe your driveway with the opposite light to see if there is any shadow, because many drivers park their broken cars on the side of the road without turning on the small lights or breaking the lights, which is very dangerous. When there is no rain and fog, don't turn on the rear fog light, which will interfere with the driver's observation of your brake light number.

7. When driving on a mountain road, it is best to open the window and turn down the volume of the stereo, so that it is easy to hear the warning of the other vehicle. Try to keep above 3000 revolutions when climbing the mountain. At this time, the engine torque will be around the peak, which can improve the maneuverability of the car. Remember to honk the horn before entering the corner, and when you don't reply, you can press another lane appropriately, which can reduce the roll. When turning around, you should honk the horn in advance, press the opposite lane, and return to your own lane when turning the center (the opposite vehicle will also slow down when turning around, so the chance of pressing the opposite lane is less than usual).

When going downhill, shift to the third or fourth gear depending on the gradient, slow down with the help of the working resistance of the engine, brake hard to a controllable speed before entering the corner, lower the gear by one gear, release the brake and enter the corner, and then shift up depending on the road conditions after the corner. Never step on the brakes for a long time to slow down, in case the brakes overheat and fail.

8. When driving on sandy roads, it is necessary to properly put a gear to reduce the speed of driving force, so as to reduce the torque output and prevent the wheels from slipping. Before turning, use the straight road to slow down to a reasonable speed and avoid braking in the corner. The control of the steering wheel should be relaxed and properly adjusted. Grasping the steering wheel will only make you tired, and it is difficult to adjust when the vehicle swings, making the vehicle out of control.

9. Pay more attention to street signs and slogans. Unreasonable street signs are also useful. When passing through the traffic police team, you should try to observe the speed limit sign within 10 km, which is the main activity scope of the traffic police. Nowadays, many small places also have the means of measuring speed to generate income.
