According to the Road Traffic Safety Law of the People's Republic of China, the alcohol content in the blood of driving motor vehicles after drinking should be greater than or equal to 20mg/ 100mL and less than 80mg/ 100mL. If the alcohol content in the blood is still higher than this range after sleeping for 9 hours, it belongs to drunk driving. If it is below this range, it is not drunk driving. In addition, drunk driving is not judged by the time after drinking, but by the alcohol content in the driver's blood. Generally speaking, the time for alcohol to dissipate is about 7- 10 hour, but the specific time varies from person to person. If you drink too much, you'd better drive after 24 hours. Driving a motor vehicle after drinking is very dangerous, which will affect vision and reaction ability. And it is easy to cause traffic accidents. We must pay attention to avoid drunk driving.
The standard of drunk driving is: the standard of drinking and driving is greater than or equal to 20mg/ 100ml and less than 80 mg/100 ml; The drunk driving standard is greater than or equal to 80mg/ 100ml. Taking the alcohol content in blood as 80mg/ 100mL as the dividing line between drinking and drunkenness, when the alcohol content in driver's blood reaches 80mg/ 100ml, the probability of traffic accidents is 2.5 times higher than that without alcohol in blood.
To sum up, whether sleeping for 9 hours after drinking is still drunk depends on the individual's alcohol metabolism and alcohol consumption. In order to avoid the risk of drunk driving, you should wait for the complete metabolism of alcohol before driving, and obey the traffic laws.
