Do Breathalyzer Tests Ever Fail?

A lot of people are shocked when they are pulled over for drinking and driving. A lot of people assume that they are going to be fine when they take their breathalyzer test. They are very surprised when they see that the test says that they are over the legal blood alcohol limit.

If this has happened to you, you may be wondering whether or not it is possible for a breathalyzer test to fail. Here are a few things that could be impacting the results of your breathalyzer test.

The Breath To Blood Conversion Didn’t Work Properly

If you had a very small amount of alcohol, but have a lot of alcohol on your breath, the breath to blood conversion aspect of the breathalyzer may not have worked the way that it is supposed to.

It is important to remember that breathalyzer machines don’t actually test your blood alcohol level. If you have received a result from a breathalyzer that you believe is incorrect, you may want to request another form of testing.

Your Body Temperature Is Very High

If you are sick with a fever when you take a breathalyzer test, the results that you get may be inaccurate.

If you have a fever, you should mention this to the officer that has pulled you over. If you have already been cited, you should bring this up when you are in court. You should try to bring something that can support your statement, such as a note from your doctor.

You Recently Burped

When you burp, a lot of alcohol from your body is passed into your mouth. While breathalyzers are supposed to account for this, they may not always do so effectively.

If you recently burped, and the test results show that your blood alcohol level is very high, you may want to ask to take the test over again in a few minutes. If you do this, and the second results show a lower blood alcohol level, you may be able to avoid driving under the influence charges.

Have You Consumed Something Else That Contains Alcohol?

Every once in a while, someone is charged with drinking and driving when they haven’t had any alcohol at all. If this has happened to you, you may be wondering how these results are possible.

In most cases, this happens because the driver has consumed something besides an alcoholic beverage that contains alcohol. The most common example of this is cough syrup. Asthma inhalers can also cause inaccurate blood alcohol results.

Make sure you report this to the officer that pulls you over. If nothing else, you will want to have it documented for when you go to court.

Breathalyzer tests are mostly accurate, but that doesn’t mean that they are perfect. Failures can and do happen. If you think you have been charged with an offense that you didn’t commit, you need to hire a great DUI lawyer. They will help you to fight these charges.
