It is rumored that "drinking more water and chewing gum can escape the drunk driving test". Is this true?

The alcohol tester detects the gas in the lungs, not just the gas in the mouth. Alcohol metabolism takes time, and drinking water in a short time cannot be diluted. At the scene of the drunk driving investigation, the traffic police found that there was a suspicion of drunk driving, blew on the spot, reached the drunk driving standard, and immediately took blood tests. Therefore, drinking water and chewing gum can not change the alcohol value in the blood.

Detection process of drunk driving

1, rapid screening with test stick.

When passing through the traffic police checkpoint, the inspected driver needs to roll down the window and blow a breath at the red detection stick in the hands of the traffic police. At this time, if the test stick does not light up, the driver will successfully pass the test.

2. Conduct a breath test.

In the rapid screening, the driver may be influenced by drunken people in the car, oral air freshener and other reasons, resulting in flashing test paper. At this point, it needs to be checked again by a more accurate breath alcohol detector.

3. Blood test

Drivers who are still suspected of drunk driving after the second round of testing will be sent to the hospital for blood tests. According to the value of alcohol content in the blood, it is finally determined whether the driver is drunk by the judicial appraisal office.
