The alcohol tester can be used to determine whether to drink and drive. There are usually two methods for the detection of drunk driving: one is to detect the blood alcohol concentration of the human body, and the other is to detect the expiratory alcohol concentration. Theoretically, the most accurate way to judge whether to drink driving is to check the alcohol content in the driver's blood. However, it is often unrealistic to take blood on site in the treatment of illegal acts or routine inspection of highway traffic. The simplest and feasible method is to detect the alcohol content in the exhalation of drivers on site.
