In Illinois, and Northfield Illinois, it is illegal to drive a vehicle while impaired by alcohol or drugs. A blood alcohol content (BAC) of 0.08 percent or higher is legally considered impaired. When a driver is pulled over for suspicion of drunk driving, the police officer will ask the driver to submit to a chemical test to determine his or her BAC. Chemical tests to calculate BAC include testing the breath, blood and urine. The most commonly used test is the breath test, often referred to as a breathalyzer test.

Breathalyzer Test

The breathalyzer test measures the amount of alcohol on the driver’s breath to estimates his or her BAC. A breathalyzer test comes in two forms: 1) a portable preliminary breath test (PBT) and 2) the evidentiary breath test. Before a driving under the influence (DUI) arrest is made, a PBT may be administered roadside. Though these test results are often inadmissible in court, they can be used as probable cause to make a DUI arrest.

Illinois Implied Consent Law

Once the DUI arrest has been made an evidentiary breathalyzer test will be administered at the police station. These results are used as evidence in court. Because of the Illinois Implied Consent Law, the accused’s license will automatically be suspended if this test is refused. In Illinois the Implied Consent Law means that by getting behind the wheel of a car, you already consent to taking a chemical test if a police officer suspects you have been drinking.

Problems with Breathalyzer Test

Don’t be discouraged if you have been charged with a DUI because of a failed breath test. Breathalyzer tests are known to have error. Skilled Cook County DUI attorneys are familiar with the problems with breathalyzer tests and can enact a defense. A failed breathalyzer test does not mean that it is necessary to plead guilty to your DUI charges.

Breath testing devices need proper maintenance and calibration. A knowledgeable Cook County DUI attorney will check the maintenance logs and call the machine’s accuracy into question. In order for the test to be accurate, the police officer must administer the test correctly. Results can be inflated if the officer makes you blow into the device too long or otherwise operates the machine incorrectly. Other factors can cause a breathalyzer test to measure falsely high such as acid reflux, dentures, vomiting and mouthwash. There are ways for an experienced DUI attorney to demonstrate the inaccuracy of a breath test.
