Now time is becoming more and more important for people, and speed is just the guarantee of time, so highway is becoming the first choice for people to drive. However, there are many dangerous factors in high-speed driving. If the driver can’t grasp the driving characteristics and operation methods of expressway, it will breed the possibility of major accidents. Therefore, please be sure to read the highway safety driving dictionary carefully, so as to “be prepared for no danger”.

First of all, before going on the highway, we must carefully check the vehicles. First, we must check the fuel volume. When the car runs at high speed, the fuel consumption is more than expected. Take a car with a fuel consumption of 10 liters per 100 km as an example. When the speed is 50 km / h, driving at 100 km / h will consume 10 liters of fuel, while driving at 100 km / h on the expressway will consume about 16 liters of fuel. The fuel consumption of high-speed driving increases obviously. Therefore, when driving at high speed, the fuel should be fully prepared.

Second, check the tire pressure. When the car is running, the tire will produce compression and expansion, that is, the so-called tire deformation, especially when the tire pressure is low and the speed is high, this phenomenon is more obvious. At this time, the abnormal high temperature inside the tire will cause the separation of the rubber layer and the covering layer, or the crushing and scattering of the outer tread rubber, which will cause the tire burst and vehicle accidents. Therefore, before driving at high speed, the tire pressure should be higher than usual.

Third, check the braking effect. The braking effect of automobile plays an important role in driving safety. When driving on the highway, we should pay more attention to the braking effect. Before starting, you should check the braking effect at low speed first. If any abnormality is found, you must carry out maintenance, otherwise, it is very likely to cause a major accident.

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

After the inspection, we can get on the highway. At this time, we should pay attention to the following driving tips: first, enter the lane 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. When the normal driving of vehicles in the lane is not affected, they 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 enough safety distance from the front vehicle. The experience is that the safe distance is about equal to the vehicle speed. When the vehicle speed is 100 km / h, the safe distance is 100 m, and when the vehicle speed is 70 km / h, the safe distance is 70 M. in case of rain, snow, fog and other bad weather, it is more necessary to increase the driving clearance and reduce the vehicle speed appropriately.

Third, be careful to overtake the vehicle. When overtaking, first of all, observe the state of the front and rear vehicles, turn on the left steering light at the same time, and then slowly turn the steering wheel to the left to make the vehicle smoothly enter the overtaking lane. After overtaking the overtaken vehicle, turn on the right steering light. After all the overtaken vehicles enter the rearview mirror, operate the steering wheel smoothly, enter the right lane, turn off the steering light, and it is strictly forbidden to overtake In the middle of the journey, we need to make a quick direction.

Fourth, the correct use of the brake. It’s very dangerous to use emergency braking when driving on expressways, because with the increase of vehicle speed, the adhesion of tires to the road decreases, and the probability of brake deviation and sideslip increases, which makes it difficult to control the direction of the car. At the same time, if the rear car does not have time to take measures, there will be multiple car collision accidents. When braking in driving, first release the accelerator pedal, and then lightly step on the brake pedal for several times in a small stroke. This method can make the brake light flash quickly, which is conducive to attract the attention of the car behind.
