What happens if I refuse to take a breath or blood test?
Under the “implied consent” laws in Illinois and the United States, drivers are required to submit to testing of their blood alcohol concentration (BAC). However, implied consent only applies after a person has been arrested. You are not required to take a roadside breathalyzer test when asked, but this refusal may give an officer probable cause to arrest you. After being arrested, if you refuse to submit to a blood, breath, or urine test of your BAC, your driver’s license will be suspended for one year, and you may still be charged with DUI
