Intoxilyzer 5000EN

There has been a lot of debate surrounding the Intoxilyzer 5000 EN, which is the machine used to perform breath tests when a person has been suspected of driving while under the influence of alcohol. The machine detects a person’s blood alcohol concentration by detecting alcohol on their breath. The question, however, has regarded the reliability of this machine and this question has kept the Minneapolis DWI lawyer rather busy.

The reliability issues lie in the device’s source code. The source code is the computer code that instructs the machine on how to interpret the amount of alcohol in a person’s bloodstream based upon a breath sample. The debating had to do with the State failing to show the defense the source code. Now after years of legal battles, it does appear that the conflict is coming to an end.

Minnesota Vs. CMI


CMI is the Kentucky-based corporation that manufactures the Intoxilyzer and Minnesota had to sue them in order to have access to the source code. The reason why this source code needed to be revealed was not just because the state was unable to provide the data to attorneys, but the code was needed to prove or disprove a case.

The accuracy of the device was in question. Minnesota lost a number of DWI cases because it is believed that the results of the Intoxilyzer are not reliable. There are thousands of DWI arrests in Minnesota that are hanging in limbo because it is not known whether or not the alleged offenders were really intoxicated.

Eventually, the lawsuit between Minnesota and CMI settled and defense experts have been able to review the code in cases. This means that through the defense experts hired by a DWI lawyer Minneapolis DWI defendants have the chance to prove whether or not the Intoxilyzer was correct.

Is The Code Reliable?


A coalition of defense attorneys came together to consolidate the many arrests that were based on Intoxilyzer results alone. The code has been examined and now it is up to the court to decide if the device is functioning properly. It is very possible that it may not have been functioning properly during its use in Minnesota and this could invalidate many of the DWI arrests that have been made, allowing the defendants to move on with their lives.

With a DWI attorney Minneapolis residents arrested for DWI based solely on Intoxilyzer results are seeing their cases dismissed or their charges reduced. This means that they have to deal with no penalties or hardly any at all. The only way to ease the anxiety that being arrested for DWI causes is to make the call to your attorney and learn of your rights and the defense strategy that can be constructed for you.
