Precautions for high-speed safe driving

1. Before going to the highway to check, be sure to do a detailed inspection of the vehicle:

First, check the amount of fuel. Cars are driving at high speeds, fuel consumption is more than expected. Take a car with a fuel consumption of 10 liters per 100 kilometers as an example. Driving 100 kilometers per hour at a speed of 50 kilometers per hour consumes 10 liters, while driving 100 kilometers per hour on a highway will consume about 16 liters of fuel. The fuel consumption of high-speed driving has increased significantly. 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 compress and expand, so-called tire deformation, especially when the tire pressure is low and the vehicle speed is high, this phenomenon is more obvious. At this time, the abnormally high temperature inside the tire will produce a rubber layer and cover Separation of layers, or broken and scattered rubber of the tread caused the tire to puncture and a vehicle accident occurred. Therefore, before driving at high speed, the tire air pressure is higher than usual.

Third, check the braking effect. The braking effect of a car plays an important role in driving safety. Pay more attention to the braking effect when driving on the highway. Before starting, you should check the braking effect at a low speed. If you find any abnormality, you must repair it. Otherwise, you may cause a major accident.

In addition, the inspection of some parts such as oil, coolant, fan belt, steering, transmission, lights, signals, etc. can not be ignored.

2. After we have finished the inspection work, we can go on the highway. At this time, we should also pay attention to the following driving tips:

First, enter the traffic lane correctly. When entering the highway from the ramp entrance, you must increase the speed in the acceleration lane and turn on the left turn signal. When it does not affect the normal driving of the vehicle on the lane, enter the lane from the acceleration lane and turn off the turn signal.

Second, keep a safe distance. When the vehicle is driving at high speed, the rear car in the same lane must keep a sufficient safety distance from the front car. As a rule of thumb, the safety distance is approximately equal to the vehicle speed. When the vehicle speed is 100 km / h, the safety distance is 100 m. When the vehicle speed is 70 km / h, the safety distance is 70 m. In case of rain, snow, fog, etc. In the weather, it is necessary to increase the driving clearance and reduce the speed appropriately.

Third, be cautious about overtaking vehicles. When you need to overtake, you should pay attention to observing the status of the front and rear cars at the same time, turn on the left turn signal and confirm the safety, then slowly turn the steering wheel to the left to make the vehicle smoothly enter the overtaking lane. After passing the overtaken vehicle, turn on the right turn signal After all overtaking vehicles enter the rearview mirror, then smoothly operate the steering wheel, enter the right lane, turn off the turn signal, and it is strictly forbidden to rush in the direction during overtaking.

Fourth, use brakes properly. It is very dangerous to use emergency braking when driving on the highway, because as the speed increases, the ability of the tire to adhere to the road decreases, and the probability of braking deviation and side slip increases, making the direction of the car difficult to control. At the same time, If the following car is too late to take measures, multiple car collisions will occur. When you need to brake during driving, first release the accelerator pedal, and then step on the brake pedal lightly for multiple strokes. This way of applying the brake can make the brake lights flash quickly and help to attract the attention of the following car.

The following are the precautions put forward by netizens' personal experience:

First: hit the direction before going to the high speed, twist the maximum angle of the two front wheels to the end, carefully check the inside of your two front wheels, and check for scratches and lifting.

Second: All vacuum tires have no inner tubes and belong to low-pressure tires. There is no need to inflate the gas beyond the specified value, which will increase the probability of flat tires. In case of a vacuum tire that punctures on the highway, because of the low pressure, compared with the high-pressure tire, it is rarely bang like a high-pressure tire. This is the benefit of the low-pressure tire. Not necessarily know. So, if the car with low-pressure tires finishes playing on the front tires on the highway, as long as you guarantee not to panic and firmly control the direction, you can definitely turn the danger!

Third: Never stop on an emergency stop belt similar to a highway. There are many trucks that have been stopped for repairs, and there are many discarded screws that are not easily noticeable by you. These screw tires will stand up when they are pressed. Plunge into your tires, so that the inspection of the front tires before you go to high speed will easily become futile. The same is true when entering the service area. Do not park in the parking area.

Fourth: Most large trucks have six gears or seven gears. The car can easily return to its original speed within 100 meters due to the deceleration of the situation, but the large vehicle cannot. The heavy-duty truck has to decelerate again due to the situation. The low gear is hung up one by one, and it takes at least two or three kilometers to return to the normal original speed. And the operation labor intensity of the truck is certainly incomparable with that of the car, so out of instinct, once the driver of the big truck has the intention to overtake, he rarely changes his mind. This requires you to keenly observe the speed and distance of all trucks in front of each other. , Take a step before they implement specific operations, determine their next move, and you have the power to take the initiative to avoid safety!

Fifth: The longitudinal sight of all small cars is far less than the observation angle and distance of the big car when driving at high speed, and any car has been tested for risk in the sludge model stage before production, and all the screaming parts at speeds above 100 kilometers per hour Every effort is made to eliminate it. The streamlined body like raindrops makes the car instantly reach high speed, which is easy to make people unconscious. Therefore, remember to drive on high-speed roads. When you really need a quicker brake, you can only mitigate the damage caused by the accident, but generally you cannot avoid the disaster you need to avoid. The core of ensuring safety depends on your seconds Accurate observation and judgment.

Sixth: When rainy, snowy, or foggy weather is blocked on the accident site of the expressway, do n’t sit in the car and listen to the music Hu Kan. The distance to your car, and must stand outside the outer barrier of the highway. Don't just remember the iron book of Japanese cars, even Mercedes-Benz and BMW can't stand the national characteristics sandwiches made by large trucks. Because in our country, the overloading of the truck is normal, but it is not normal if it is not overloaded. It does not want to stop, it wants to stop too much and cannot stop!

Seventh: As long as there are conditions, you must drive on the middle lane, that is, the traffic lane. In case of any accident, there is room for maneuvering around. Secondly, beware of the size of the flat tires in the other lane. They will rush through the middle barrier to form a head-on collision. Everyone knows that the strength of head-on collision is the strongest in all accidents and the most serious consequences!
