Intoxilyzer Test

If you’re pulled over for a DUI and your field sobriety test makes the officer suspicious, you may be asked to take a breathalyzer test.  In most cases, the Intoxilyzer 5000 will be the machine used to take this test.  The Intoxilyzer 5000 is the most commonly used breathalyzer equipment for DUI.

When you agree to be tested with the Intoxilyzer 5000 after a DUI, you’ll blow into a tube that sends your breath through the machine.  Basically, the Intoxilyzer 5000 works by absorbing light at specific wavelengths.  Alcohol absorbs at specific frequencies and is measured by the Intoxilyzer 5000.

There’s a lot of debate about whether the Intoxilyzer 5000 is an accurate test of blood alcohol. Some experts believe that the Intoxilyzer 5000 will only measure alcohol at the specific designated frequency.  Still others think that other chemicals will also cause light to vibrate at the same frequency as alcohol in the Intoxilyzer 5000.  This would cause the Intoxilyzer 5000 to give a false positive result.  This would negatively affect the outcome of your DUI charge.

In addition, many experts argue that physical characteristics of the person taking the Intoxilyzer 5000 test may cause false results.  For example, someone who has a high level of ketones in the blood may have a false Intoxilyzer 5000 result.  This is a common condition in diabetics and people on very low carbohydrate diets.  When this false positive Intoxilyzer 5000 happens, it can have negative consequences on your DUI defense.

Other factors such as body temperature can also affect the Intoxilyzer 5000.  In scientific studies, the same individual tested at different body temperatures by the Intoxilyzer 5000 gave different results. The higher the body temperature, the higher the blood alcohol level according to the Intoxilyzer 5000.

All of this is to say that while many people feel like the blood alcohol result from the Intoxilyzer 5000 is absolute, the reality is that it is not foolproof.  The Intoxilyzer 5000 can give false positive results and those can have a big impact on your DUI charge and conviction.

It’s important that you consult with an attorney if you’ve been charged with a DUI.  He or she can help you to sort out the result of your Intoxilyzer 5000 test.  While you may be fearful that it is absolute evidence of a DUI, your attorney may be able to explain why your Intoxilyzer 5000 results are not accurate.  While the Intoxilyzer 5000 is heavily relied upon by law enforcement officials and the court system, it’s not always correct and there are ways to fight the results from it after a DUI.
