Those tests are set up so you will fail. Big money in DUI's. Just more government corruption to milk people out of their money.

Drunks don't make good decisions as a rule.
Just remember, you've got a good chance to beat a rap in court.
You have zero chance to beat the police on the side of the road.

While you're waiting for bail, might be a good time to review your life choices.

A breathalyzer can give a false positive reading for a number of reasons, including environmental factors, medications, and medical conditions.
Environmental factors
Chemicals
Exposure to paint fumes, gasoline vapors, or other chemicals can interfere with the breathalyzer's sensors
Temperature
The temperature of the breathalyzer or the environment can affect the reading
Medications
Cough syrups: Cough syrups that contain alcohol can increase the alcohol content in your breath
Cold medicines: Some cold and cough medications contain small amounts of alcohol
Other medications: Albuterol, budesonide, and salmeterol can cause false positives
Medical conditions
Gastroesophageal reflux disease (GERD): Stomach acid can flow back into the mouth, causing a false positive
Ketoacidosis: A condition that can cause the body to produce acetone, which can be mistaken for alcohol
Low-carb diets: The body produces ketones, including acetone, which can be mistaken for alcohol
Other factors
Operator error: Untrained officers may make mistakes that lead to false positives
Mechanical issues: The breathalyzer device itself may be malfunctioning
Fermented foods: Foods like kimchi, sauerkraut, and soy sauce can produce trace amounts of alcohol

So a sober person can throw away thousands of dollars to defend themselves from over reach by county and city foot soldiers.
I don't drink. But am out in bars on some weekends. Just part of being in the music business. I've had cops tail me leaving a bar. There will be a day that I'm harassed because some power hungry cop thinks he has a drunk driver.
