In China, tens of thousands of traffic accidents are caused by drunk driving every year; more than 50% of accidents causing death are related to drunk driving. The harm of drunk driving is shocking and has become the number one "killer" of traffic accidents. ".

Even if the traffic law enforcement department intensifies the investigation and punishment of drunk driving, there are still people who take chances and drive vehicles under the influence of alcohol, leading to car accidents and endangering the safety of themselves, others and society.

Existing cars cannot prevent drivers from drinking and driving, and excessive drinking may cause health emergencies for the driver, such as sudden myocardial infarction, angina, etc., which may cause the vehicle to be out of control, thereby creating greater safety concerns. question.

Utility model content
