Whenever there is a holiday or a gathering of friends, people will drink more or less alcohol. We often see drunken fights, drunken driving and deaths in car accidents. According to the traffic control department statistics, the city each year killed at the wheel of more than 200 people, about 50-60% of car accidents and drinking-related. Medical evidence shows that alcohol has both a short-term stimulating effect on the human brain, making people false excitement, and anesthesia, making people unresponsive, and even behavior out of control. While driving a motor vehicle requires the driver to keep a clear head when driving, for the rapidly changing traffic conditions on the road, to make a rapid judgment within 0.75 seconds, and take appropriate technical measures to ensure the safety of traffic. Medical research proves that when the human body contains 30 mg of alcohol per 100 ml of blood, people will be talkative; when the body contains 40 mg of alcohol per 100 ml of blood, people’s actions are clumsy; when the body contains 60 mg of alcohol per 100 ml of blood, people will chatter; when the body contains 80 mg of alcohol per 100 ml of blood, people’s emotions are excited or slow; when the body contains 120 mg of alcohol per 100 ml of blood, people will be excited or slow to react; when the body contains 120 mg of alcohol per 100 ml of blood, people will be excited or slow to react. When the body contains 120 mg of alcohol per 100 ml of blood, people will be tired and sleepy; when the body contains 200 mg of alcohol per 100 ml of blood, people will lose control of urination; when the body contains 400 mg of alcohol per 100 ml of blood, people will appear coma and shock. General people drink 1-bottle capacity 640 mg, alcohol content of about 5% of the spleen wine, 100 mg of blood alcohol content of 0.5 grams – 0.7 grams, sobriety time of 7.2 hours, the accident rate of 55%; drinking 3 bottles of spleen wine, 100 mg of blood alcohol content of 1.2 grams, sobriety time of 10 hours, the accident rate of 65%; drinking 5 bottles of spleen wine; 100 mg of blood alcohol content of 1.8 grams; sobriety time is 13 hours, the accident rate is 90%. According to the relevant provisions of the traffic control department, when the motorist’s blood alcohol content R10 mg/100 ml, can be considered drunk driving; when R100 mg/100 ml for drunk driving. Some people think that they have a large amount of alcohol, although drinking but not drunk, or can drive. In fact, this view is very wrong. After alcohol enters the body, no matter how much it is, it will cause damage to the nervous system and make people’s judgment of things biased, all affecting their ability to react to things to varying degrees. In the case of a driver who has not consumed alcohol, the reaction time from visual perception to the action of applying the brakes is 0.75 seconds when a dangerous situation is detected in front of him, and the reaction time is 2-3 times slower when he is still able to drive after drinking alcohol, which greatly increases the possibility of traffic accidents. If a person is driving slightly drunk, he or she is 16 times more likely to be involved in an accident than if he or she is driving without alcohol. For the sake of others and the well-being of your family and yourself, please remember never to drink and drive.
