Will Non-Alcoholic Beer Show On A Breathalyzer?

Many people who are planning to drive often wonder whether non-alcoholic beer can show on a breathalyzer. This is a valid concern, especially for individuals who have to take a breathalyzer test for work or legal reasons.

So can non-alcoholic beer show on a breathalyzer? Read on to find out…

Will Non Alcoholic Beer Show Up On A Breathalyzer?

No, in the vast majority of cases, non-alcoholic beer will not show up on a breathalyzer. This is because breathalyzers are designed to detect the presence of alcohol in the breath, and non-alcoholic beer typically contains less than 0.5% alcohol by volume (ABV).

However, there are some factors that can affect whether non-alcoholic beer will show up on a breathalyzer. For example, drinking multiple non-alcoholic beers within a short period of time can increase the amount of alcohol in your system and trigger a positive breathalyzer result if the test is taken soon after drinking.

How Breathalyzers Work

Breathalyzers are diagnostic devices that measure the amount of alcohol in a person’s breath. They are commonly used by law enforcement to determine if a person is driving under the influence of alcohol. The device works by analyzing the components of a person’s breath, with alcohol being the component of interest.

The original version of the Breathalyzer™ included a mouthpiece and two chambers containing liquid connected to a meter that detects a change in color. To use the device, the subject exhales through the mouthpiece into a test chamber filled with a reddish-orange solution of potassium dichromate (K 2 Cr 2 O 7 ). The alcohol in the breath reacts with the potassium dichromate, causing the solution to change color. The meter then detects the change in color and converts it into an alcohol concentration reading.

Modern breathalyzers use advanced technology to measure the amount of alcohol in a person’s breath. They may use infrared spectroscopy, fuel cell technology, or other methods to analyze the breath sample. The device then calculates the blood alcohol content (BAC) based on the amount of alcohol detected in the breath sample.

It’s important to note that breathalyzers are not perfect and can sometimes produce inaccurate results. Factors such as mouth alcohol, residual alcohol in the mouth, and certain medical conditions can affect the accuracy of the device. However, breathalyzers are still considered a reliable tool for detecting alcohol in a person’s breath and are widely used by law enforcement agencies.

Can Non-Alcoholic Beer Ever Show on a Breathalyzer?

Factors that Affect Breathalyzer Results

The accuracy of a breathalyzer test can depend on various factors, such as the type of breathalyzer used, the individual’s metabolism, and the amount of time between consuming alcohol and taking the test. Additionally, certain substances, such as mouthwash or gum, can interfere with the accuracy of the test.

Alcohol Content of Non-Alcoholic Beer

Non-alcoholic beer typically contains less than 0.5% alcohol by volume (ABV). This is significantly less than the amount of alcohol found in regular beer, which can range from 4-8% ABV. While the alcohol content in non-alcoholic beer is minimal, it is still possible for it to register on a breathalyzer test, depending on certain conditions.


Does Non Alcoholic Beer Show Up On Breathalyzer tests?

No, non alcoholic beer will not show up on breathalyzer tests. The only possible exception is if you drink a lot of non-alcoholic beers and then quickly take a breathalyzer test, but even then, it is unlikely to produce a positive result.

How Long After Drinking Non-Alcoholic Beer Can You Drive?

Although non-alcoholic beer may contain trace amounts of alcohol, it is still legal to consume non alcoholic beer and drive.

Non alcoholic beer cannot make you drunk, so there is no need to wait before driving after drinking non alcoholic beer.

Will Heineken 0.0 Show On Breathalyzer Tests?

No, Heineken 0.0, a non-alcoholic beer, will not show on a breathalyzer test as it contains 0.0% alcohol, ensuring a clean breathalyzer reading every time.

Will Budweiser Zero Show Up On A Breathalyzer?

No, as it doesn’t contain alcohol, Budweiser Zero will not show up on a breathalyzer test.

Will O’Douls Show Up On A Breathalyzer?

No, O’Doul’s, a non-alcoholic beer containing less than 0.5% alcohol, won’t trigger a breathalyzer due to its extremely low alcohol content, maintaining a clear breathalyzer result.


Non-alcoholic beer contains a very small amount of alcohol, usually less than 0.5% ABV. While this is not enough to cause intoxication, it can still be detected by a breathalyzer. Therefore, if you are required to take a breathalyzer test, it is best to avoid consuming any type of alcoholic beverage, including non-alcoholic beer.

It is important to note that the accuracy of breathalyzers can be affected by a variety of factors, including the type of breathalyzer used, the calibration of the device, and the individual’s metabolism. Therefore, it is always best to err on the side of caution and avoid consuming any alcohol before driving or operating heavy machinery.

Overall, while non-alcoholic beer may seem like a safe alternative to regular beer, it can still have an impact on a breathalyzer test. It is important to be aware of this fact and make responsible decisions when it comes to consuming alcohol.
