How can I Fight Breath Test Evidence?
The results of a breath test will typically be a key part of the evidence against a driver who is charged with DUI (driving under the influence). After making an arrest for suspected drunk driving, law enforcement will ask a driver to submit to a breath test or blood test. This chemical test is administered to determine the driver's blood alcohol concentration. If it is found to be .08% or greater (or .04% or greater for a commercial driver), the driver will most likely face criminal charges for DUI and statutory summary suspension by the Secretary of State.
Failing or refusing a breath test may have serious consequences, but there are ways for an attorney to challenge an alleged refusal or a "failed" breath test. With our experience in this field and our training in DUI defense, the Chicago DUI attorneys from law firm can effectively challenge breath test results for our clients.
Penalties for Failing a Breath Test
A driver who fails a breath test (takes a test that shows a result of .08% or greater) may face the following penalties:
- First breath test failure - 6-month suspension of driving privileges.
- Second or subsequent breath test failure within 5 years - 1-year suspension of driving privileges.
A driver will also most likely face DUI charges in criminal court, based upon the evidence of the failed test and any other evidence, such as the arresting officer's testimony about poor performance on field sobriety tests or other observations that are considered to indicate intoxication.
