An OVI arrest refers to a situation where a person is arrested for operating a vehicle while impaired by alcohol or drugs in Ohio. OVI stands for "operating a vehicle impaired," and it is a broader category that includes alcohol intoxication and any impairment from illegal drugs, prescription drugs, or over-the-counter drugs. In Ohio, the parameters of alcohol or drug concentration in an individual’s blood, blood serum/plasma, breath, or urine that constitute an OVI are detailed in the law. An OVI conviction has severe consequences beyond criminal penalties, including a permanent criminal record that can harm future personal and professional prospects. If you are charged with an OVI, it is essential to work with a criminal defense lawyer who handles OVI cases to investigate the circumstances of your arrest and determine which of several possible OVI defenses might help to have your charges dismissed or reduced.
