For drunk drivers, the higher the alcohol content in their blood, the greater the chance of a crash.
When the alcohol content in the blood of the driver reaches 80mg/100mL, the probability of traffic accidents is 2.5 times that of the traffic accidents when the alcohol content in the blood does not contain alcohol; when the concentration of the alcohol reaches 100mg/100mL, the probability of traffic accidents is 4.7 times that of the case that the alcohol is not contained in the blood. Even in a state of drinking a little amount of alcohol, the risk of traffic accidents can reach about 2 times of that of the state of non-drinking.
The harm of drunk driving is large, and a safe driving system capable of preventing drunk driving of an automobile is lacked at present. Accordingly, a driver of the art provides a drunk driving prevention safe driving system to solve the problems set forth in the above background art.
