DuPage County DUI Defense Lawyers

Challenging Field Sobriety Testing and Chemical Testing

If you are driving home after having a few drinks after work, the appearance of flashing red lights behind your vehicle can be a justifiable cause for alarm. Illinois law enforcement agencies and prosecutors aggressively pursue convictions in driving under the influence cases. Whether you are arrested for a first time driving under the influence charge (DUI) or you are a repeat offender involved in an accident that causes serious injury, our experienced DuPage County DUI defense attorneys at Ramsell & Kunowski, L.L.C. can guide you through the court process.

Our criminal defense lawyers carefully scrutinize every aspect of your interaction with the arresting officer to identify effective defense strategies. While we customize our defense strategy to the facts of your particular DUI charge, some of the defense we might utilize include:

  • Insufficiency of the evidence supporting the initial stop;
  • Officer’s lack of training or improper administration of field sobriety tests (FSTs);
  • Failure to properly comply with the waiting period prior to a breath test;
  • Improper mixing or storage of blood sample for testing;
  • Contamination of a blood sample;
  • Inherent unreliability of FSTs;
  • Suppression of evidence obtain in an unlawful search (e.g. open beer cans in the passenger compartment);
  • Exclusion of statements that are not voluntary or the result of Miranda violations; and
  • We Wrote the Book on DUI Defense in Illinois.
