"No Refusal" Weekend in DuPage County, Illinois: Those darn citizens, trying to "skirt the law by refusing to be tested" via breath test. How dare they know that breathalyzer equipment is notoriously unreliable. How dare they rely on their constitutional rights. As Knoxville DUI attorneys, we generally recommend that persons stopped on suspicion of DUI decline the field breahtalyzer because of its known lack of accuracy. There should be no stigma in insisting that the police use only the most accurate possible test to determine whether a violation has occurred. And taking blood test is the most accurate test.
