Each state's driving laws are different, and each state also has different penalties for driving under the influence of alcohol. If you are underage, and cannot legally consume alcohol, there may be even different penalties for that. Ohio, like any other state, has its own set of laws and punishments.

Legal Drinking Age in Ohio

The legal drinking age in Ohio is 21. If you are younger than the age of 21, you are not legally allowed to drink alcohol.

What Constitutes DUI in Ohio?

If you are an adult of legal drinking age in Ohio, the blood alcohol limit is .08 percent. However, if you are underage, the blood alcohol content (BAC) has to be between .02 percent and .08 percent for you to be charged with Operating a Vehicle After Underage Consumption (OVAUC).

Sobriety Tests And License Suspension

If you are stopped under suspicion of DUI in Ohio, you will likely be asked to perform a sobriety test. You may refuse to take the test (such as a Breathalyzer) but if you do, your license will be automatically suspended for one to five years.

Penalites for Underage DUI

Underage DUI penalties in Ohio include license suspension for 60 days up to two years. You'll also be required to retake a driving class and complete your license exam again; four points will be added to your license; and you will have to pay a license reinstatement fee when your punishment has been served.

Other Penalities

If you are found to be driving a car while your license is suspended, you may face even more penalties. You should not let someone who has a suspended license drive your car, as you may face suspension as well if caught.
