As an Illinois DUI lawyer, I am asked this question all the time by random people all over the city. As soon as someone finds out I am a criminal defense lawyer, the most common question is, “What should I do if I am stopped by the police for a DUI?”The most common answer I give these people is that, in Illinois, the best thing to do is not submit to a breathalyzer test. The reason for this is because when you submit to a breathalyzer test, you give the police evidence to use against you in court. When you submit to a breathalyzer exam it allows the state to use more evidence against you to prove you guilty beyond a reasonable doubt. In addition, the State can add an additional DUI charge for blowing over .08 on the breathalyzer machine.While this is my typical answer, there are always reasons why one might consider blowing into the breathalyzer machine. These rules also do not apply in other states as I can only recommend this information to clients and people in the state of Illinois. Should you ever have any questions about a DUI charge you can always contact DUI lawyer Mike Noris or myself DUI lawyer John Callahan at any time.
