Chicago criminal defense attorneyThe moment a driver is pulled over for suspicion of driving under the influence, he or she is often faced with a series of field and sobriety tests—including blood-alcohol content (BAC) tests—that ultimately help determine their fate in a court of law. Whatever the outcome, the driver found guilty of a DUI offense faces everything from the loss of driving privileges and serious prison time to hefty fines and community service. Depending on the severity of the conviction, the driver’s life can be affected for months, and even years following the DUI arrest.

The Science Behind the Breathalyzer

When so much rests on the results of sobriety tests, it is understandable that the reliability of such tests are questioned and challenged. So, just how reliable are breathalyzers? How do they work, and can they be trusted? In short, a breathalyzer is a modified infrared radiation spectrometer. That is a fancy term for a device that measures the absorption of organic compounds in the blood stream - in this case, alcohol. When you blow into a breathalyzer, the alcohol that is in your blood transfers through to your breath, and the device calibrates to read the concentration of alcohol in your system.


Chicago DUI Defense attorneyIf you find yourself arrested for driving under the influence in the state of Illinois, refusing a BAC (blood alcohol concentration) test of any kind can mean severe consequences for you from that very moment. If you have not yet been arrested for DUI, however, refusing a BAC test may offer a few advantages as you move forward with the defense of your case.

You Have Decided to Refuse a Breathalyzer Test. Now What?

Refusing a test before you have been arrested and taken into custody prevents law enforcement from collecting any incriminating evidence against you in a court of law. At this stage, you still have the option to shape the course of your fate in terms of charges and the penalties that accompany them, but how you proceed with the refusal is important.


Chicago DUI defense attorneyWhen you are pulled over for the suspicion of driving under the influence, you have the right to refuse to submit to a breathalyzer test if you wish to do so. There are, however, consequences to this option, just as there are consequences to submitting to the test if you have in fact been consuming alcohol. If you are conflicted as to whether to submit or not, it is helpful to familiarize yourself the penalties associated with both options before you make your decision.

Standard DUI Penalties in the State of Illinois

For starters, if you decide to submit to a breathalyzer test and are found to be over the legal limit, your driving privileges will be automatically suspended for six months for your first offense. The suspension doubles to one year for a second or subsequent test failure. The suspension applies regardless of whether prosecutors push for a conviction on DUI charges. If you are convicted of DUI, you are looking at a combination of the following:

The moment you see an officer's lights flash behind you, the decisions you make from that point on will set the tone for your entire case. Even if you are guilty of driving under the influence, one of the best things you can do for yourself is to remain respectful and comply with the police, to the best of your ability. However, this does not mean you are required to incriminate yourself.

Here are some common requests you will face from an officer who pulls you over for the suspicion of DUI and how you should handle each one:

You should not delay pulling over to the side of the road; you should comply with the officer’s direction as quickly as possible, so long as you can safely park your vehicle. The sooner you stop and park your car, the better your chances of avoiding unnecessary tension and conflict once the officer approaches you. You want to cooperate from start to finish, and pulling over immediately, when the officer directs you to do so, is the first signal that demonstrates you are taking the matter seriously and that you intend to comply.

If you have in fact been drinking and driving, the moment the law enforcement officer collects evidence against you, you are at risk for losing your license, serving jail time, paying hefty fines, and possibly blemishing your future career options, as DUI convictions can often ruin your eligibility for certain jobs.

The BAIID Consequence

Along with having your license suspended, paying fines, and serving possible jail time, you may also face another serious restriction as you reclaim your driving privileges. Should you decide to submit to a blood alcohol concentration (BAC) test upon your arrest and are found guilty of driving while intoxicated, you will likely be required to have a breath alcohol ignition interlock device (BAIID) installed in your vehicle if you are eligible for driving relief. The BAIID installation is required for a set period of time determined by the court, depending on the nature of your conviction, and you are required by law to utilize it any time you get behind the wheel.

So, what actually happens when you are pulled over for suspicion of DUI? Are the events that unfold as harsh or as scary as we hear they are? The moment an officer pulls you over, they require you to present your license, registration, and proof of insurance, and you are then asked to submit to a field sobriety test if the officer believes you have been drinking.

When drivers suspected to be operating under the influence are pulled over, they are subject to a BAC test, which is heavily relied upon in the during criminal prosecution as supporting evidence for the crime.
