Can a driver be charged with OWI for driving under the influence of a legally prescribed medication?

Answer: Yes, if the medication impairs the ability to drive safely

Indiana's OWI law applies to any substance — including legal prescription drugs — that impairs a driver's ability to safely operate a vehicle.

What is a 'per se' OWI law?

Answer: A law that makes it illegal to drive at or above a set BAC regardless of actual impairment

A per se law means that reaching or exceeding the legal BAC limit (0.08%) is itself the offense, without needing to prove actual impairment.

What is an ignition interlock device (IID)?

Answer: A breathalyzer connected to the ignition that prevents the car from starting if alcohol is detected

An IID requires the driver to blow into a breathalyzer before starting the car; if alcohol above a set threshold is detected, the engine will not start.

How does alcohol primarily affect a driver's ability?

Answer: Slows reaction time, impairs judgment, and reduces coordination

Even small amounts of alcohol slow reaction time, impair decision-making, and reduce the coordination needed for safe vehicle control.
