When an officer arrests a driver for DUI (called ‘OVI’ in Ohio), the officer typically requests that the driver consent to a blood, breath, or urine test. However, a statute in the Ohio Revised Code (section 4511.191) says a driver arrested for OVI implicitly consents to those tests. Can a driver arrested for OVI revoke that consent? This question has not been directly addressed in Ohio but was recently answered by the Supreme Court of Colorado.
