Cops are always there near clubs or bars, charging drunk drivers with a DUI. People under the influence of alcohol are caught using a breathalyzer. Whenever a cop suspects that the driver is impaired, he might ask you to pull over and take a breathalyzer test.

Despite having all the tips and tricks up your sleeves, the best way to go is to drink moderately to keep your blood alcohol level under the legal drinking limit.

Chugging 2-3 cans of your favorite beer is fine as it will keep your blood alcohol level (BAC) to a moderate level. But, if you are intoxicated – consider yourself busted. If your BAC is near 0.08, there are chances you can save yourself from a breathalyzer test using a few hacks. 

Check out the article to find out how this clever device works and 10 ways you can beat a breathalyzer test.

How Breathalyzers Work to Get Your BAC

Breathalyzers are portable, small devices used to detect the concentration of alcohol in the human body called BAC level. These breath testers are highly used by traffic police to check the intoxication level of a person – or for professional people like pilots before they board a plane. Some people opt for keeping a personal breathalyzer in cars to keep track of their BAC level.

All you have to do is blow into the device, and it measures the amount of alcohol in your breath. The alcohol in your breath comes across with potassium dichromate (an orange solution). If you’re drunk, the solution gets green, signaling electrical patterns for the device to measure your BAC level. 

What Alcohol Blood Level Is Drunk

In order to avoid any trouble, keep your BAC level under the legal drinking limit as defined by your State’s government. In the U.S., you are considered drunk if your BAC is 0.08% or above. For teens (not eligible to drink anyway), and commercial truck drivers, the government has set a lower “zero tolerance level,” which is around 0.02%.

If the driver exceeds the legal limit of BAC, they can get their driving license suspended or have to pay heavy fines. In serious cases, this can turn into a felony, making you take a trip to prison. In order to stay on the safer side, make sure to comply with your State’s laws.

How to Beat a Breathalyzer: The 8 Simple Secrets to Outsmarting a Breathalyzer Test

How to Beat a Breathalyzer

There are several ways to pass a breathalyzer test, but keep in mind that these tricks are good when your BAC hovers around the legal drinking limit. If you’re intoxicated way above 0.08% then things can get more difficult.

So, try to keep your alcohol consumption to a moderate level to avoid becoming a notable DUI suspect. Be cautious, as some useless hacks might cause your BAC to increase instead of lowering it. But this article is not about those unreliable tricks. Read on to find some of the fastest ways to pass a breathalyzer test and help get rid of alcohol breath.

1. HyperVentilating

In this method, a person is supposed to breathe at a rapid speed for at least 20 seconds. Kinda becomes hard when a cop is staring at you. Hyperventilating makes way for fresh air to enter your lungs replacing the bad alcohol breath.

It can lower your BAC by 10%. This is the most effective of all the methods. But requires extensive caution. If a cop finds out that you’re trying to cheat a breathalyzer by breathing fast, they might still charge you and ask you to retake the test.

2. Burping

Have you ever thought burping could save your life? When it comes to a breathalyzer test, this disgusting habit can be a game-changer. A burp occurs when the digestive system expels gas from the stomach in response to the consumption of food and drinks. 

However, it is scientifically proven that burping into the breathalyzer won’t have any effect on the reading and will show your exact BAC. It’s kind of hard to fool these little machines. A simple cheat in this situation is to take deep breaths and let it out as many times as you can before you even get pulled over by a police officer.

This will help you alter the readings as burping can introduce clean air into your breath, diluting the alcohol concentration momentarily.

3. Chewing Gums and Mints

Gums and mints will surely reduce the scent of the alcohol from your but may have minimal effect on your BAC. These items make your mouth water a bit more, which could thin out any leftover alcohol in your mouth.

The breathalyzer shows altered results if the person was chewing gum prior to the test or has hidden a piece of gum in the mouth while taking the test.

In most States, cops don’t allow you to take a test if you are chewing gum or mints. You have to wait at least 5-20 minutes after removing the gum to take a breathalyzer test.

4. Keeping Yourself Hydrated

Drink plenty of water before and during your drinking session. This will allow you to have a full stomach while consuming alcohol in moderation. According to NIHWater will help dilute the alcohol in your system. A combo of hyperventilating and water will help reduce your BAC level.

5. Eating Peanut Butter

Sodium present in peanuts can help neutralize ethanol. Some folks suggest eating a spoonful of peanut butter will reduce the BAC to a great extent, while in reality, it only reduces it by 0.01%. Try having a peanut butter sandwich if you really want to fool a breathalyzer test.

6. Drinking On A Full Stomach

It’s Saturday night, and you’re going to a pub to chug a few beers with your buddies. To prevent your blood alcohol level from reaching its peak, always have some grub in your belly. It takes time for alcohol to metabolize on a full stomach. This will automatically lower your BAC level and help you smoothly pass a breathalyzer test.

7. Sucking on Pennies

This trick was considered a life-saver back when breathalyzers tried to figure out how much booze was in your breath by doing some chemistry stuff. Tastes gross! But it will help you reduce your BAC to a minimal extent. Sucking on coins works when it is made of copper or zinc which dilutes the alcohol content in your mouth. However, it will only mask the odor of alcohol and cannot trick modern breathalyzers.

8. Exercising and Waiting out

When you can sense the booze is totally kicking in, try some vigorous exercise to lower your BAC. Excessive sweating and breathing will help you get rid of alcohol faster. But exercising can be a tough option when you’re tipsy. The best way is to wait out till you feel sober again.
