How to Beat a Breathalyzer Test [7 Secret Tips]

How to Beat a Breathalyzer

Let’s be honest: nobody enjoys being asked to blow into a breathalyzer by the cops. The situation worsens if you’re driving after a few drinks and aren’t sure you’re impaired. You might have methods like sucking on a penny, gargling with mouthwash, or simply holding your breath.

However, you should know that these methods aren’t much more effective than simply flailing your arms in the air. In other words, they are useless. They might harm you more than benefit.

This page will explain the science behind breathalyzers, how they calculate your BAC, and why you can’t fool one. We’ll also tell you the best, safest ways to ace or formally challenge the test.

How to Beat a Breathalyzer: The 7 Secrets to Outsmarting a Breathalyzer Test

How to Beat a Breathalyzer

Following are some helpful tips to beat a breathalyzer. You will also find the drawbacks of each method.

1. Stall for Time: How to Delay Taking the Test

Putting off an alcohol test as long as feasible is one strategy for increasing your likelihood of passing. This will allow your body to flush the alcohol from your system and reduce your blood alcohol content.

Alcohol is absorbed by the blood and later metabolized by the liver. The liver’s capacity to process alcohol is roughly one drink per hour, give or take, depending on your weight, gender, and other factors.

You can pass the test if you wait until your blood alcohol content (BAC) has decreased. Asking the officer questions, requesting legal representation, or even using the restroom are all acceptable diversion tactics. But remember that missing your scheduled test time could result in legal trouble or the suspension of your driver’s license.

2. Freshen Up: Why Mouthwash and Mints Won’t Help You

Using mouthwash or breath fresheners can temporarily lower the quantity of alcohol on your breath before a breathalyzer test. The alcohol content of these items may temporarily alter the results of a breathalyzer test. It’s possible to give off a suspicious stench if you use too much mouthwash or breath freshener, so moderation is key.

3. Breathe Fast: How to Hyperventilate Before Blowing

Before undergoing a breathalyzer test, hyperventilating might temporarily lower your blood alcohol content. This method entails holding your breath for a few seconds after each deep inhalation, followed by a rapid exhalation.

This method will raise your heart rate, speeding up your body’s alcoholic beverage metabolism. However, prolonged hyperventilation can cause lightheadedness or fainting, so be careful.

4. Let It Out: Why Burping Can Make Things Worse

You can temporarily lower your blood alcohol concentration (BAC) by burping to release vaporized alcohol from your stomach. Burp means taking a deep breath, holding it, and then abruptly letting it go.

This method will force your stomach to empty any accumulated alcohol vapors. It’s important to remember that too much burping might trigger nausea and vomiting from acid reflux.

5. Drink Up: How Water Can Hydrate You But Not Lower Your BAC

Drinking water in small amounts and at regular intervals is advised to prevent water intoxication. Furthermore, if you have consumed a lot of alcohol, consuming water may not reduce your blood alcohol content sufficiently for a breathalyzer test.

Remember that the only foolproof method is never to drink and drive to be confident of passing a breathalyzer test. Act responsibly and put your and others’ safety first if you’re ever in a scenario where a breathalyzer test is required.

6. Eat Up: How Fatty Food Can Affect Your Alcohol Absorption

By eating fatty foods before taking a breathalyzer test, a person can quickly lower the amount of alcohol in their blood. If you eat fatty foods before drinking alcohol, it can slow down how quickly the alcohol gets into your system. You must remember that overeating fat can hurt your stomach.

7. Don’t Just Say No: Why Refusing the Test Is a Bad Idea

If you refuse a breathalyzer test, it might cost you your driving privileges or will end you up in jail. However, since there are serious legal repercussions for failing the test, such as fines, jail time, and license suspension, refusal may be preferable. But for that purpose, you must come up with some valid reason.


How to Beat a Breathalyzer

Is there a way to beat a home breathalyzer?

No, there is no reliable or safe way to beat a home breathalyzer. The device will measure the alcohol content in your breath that reflects your BAC. Some methods that people claim can beat a breathalyzer, such as hyperventilating, burping, or drinking water, are either ineffective or risky. The best way to avoid failing a home breathalyzer is to drink responsibly and not drink when you need to drive or perform other tasks.

Will throwing up help pass a breathalyzer?

No, throwing up will not help you in this regard. Once alcohol is absorbed into your bloodstream from your stomach and intestines, it will remain there until your liver breaks it down. Throwing up may remove some of the alcohol that has not been absorbed yet, but it will not lower your BAC once it is already there. Throwing up can also make you dehydrated, worsening the effects of alcohol.

Can you hack a breathalyzer?

No, you cannot hack a breathalyzer. The device estimates the alcohol in your breath from your lungs and blood. It uses a chemical reaction or an infrared sensor to detect the presence of alcohol molecules. There is no way to trick or tamper with the device without being noticed by the officer or the device itself.


Unfortunately, there is no foolproof method to pass a breathalyzer test. Avoiding intoxicated driving is the surest path to success on the exam. Some people have found that delaying time, hyperventilating, or consuming fatty meals before drinking might reduce their blood alcohol content on a breathalyzer test.

These techniques, while popular, are not without their risks. Act correctly, and putting your and others’ safety first is always preferable. Therefore keep in mind that refusing the test may have significant legal repercussions.
