Using Independent BAC Testing as Evidence in a DUI Case

When someone is arrested and they want to challenge the result of a breath, blood, or urine test, they need to get an independent analysis test immediately upon release from jail.

Blood and urine tests are administered by law enforcement officials, police officers, or technicians at the police station. If there is an accident and a mandatory chemical test is needed, that is sometimes done at the hospital and is often a blood test. Contact an experienced criminal attorney if you are interested in learning more about using independent BAC testing as evidence in a DUI case.

Likelihood of Independent Testing in DUI Cases

Using independent BAC testing as evidence in a DUI case is a relatively rare circumstance because it is so difficult to get the test administered close enough in time to the act alleged when the person was driving while under the influence to make that test worthwhile.
