Ohio DUI Laws and Penalties Overview

3 min read

Driving under the influence (DUI) in Ohio is a serious offense with strict penalties designed to reduce impaired driving and protect road safety. Understanding the legal limits, testing procedures, and potential consequences is essential for any Ohio driver.

In Ohio, it is illegal to operate a vehicle with a blood alcohol concentration (BAC) of:

  • 0.08% or higher for drivers 21 and older
  • 0.02% or higher for drivers under 21
  • 0.04% or higher for commercial drivers

Law enforcement may use breath, blood, or urine tests to determine BAC levels. Refusing to submit to a chemical test results in an automatic license suspension under Ohio's implied consent law.

Penalties for First, Second, and Third Offenses

Penalties vary based on the number of prior offenses within ten years and BAC level at the time of arrest:

First Offense:

  • 3-day minimum jail term (or driver intervention program)
  • License suspension of 1–3 years
  • Fines between $375–$1,075
  • Possible ignition interlock device (IID) requirement

Second Offense:

  • 10-day minimum jail term
  • License suspension of 1–7 years
  • Fines between $525–$1,625
  • Mandatory IID upon reinstatement

Third Offense:

  • 30-day minimum jail term
  • License suspension of 2–12 years
  • Fines between $850–$2,750
  • Mandatory IID and vehicle immobilization

For high-test offenses (BAC 0.17% or higher), enhanced penalties apply, including longer jail terms and mandatory use of an IID.

Ohio Administrative License Suspension (ALS)

Refusing a chemical test or testing over the legal limit triggers an immediate ALS:

  • First refusal: 1-year suspension
  • Second refusal: 2-year suspension
  • Third refusal: 3-year suspension

You may request an administrative hearing within 30 days to contest the suspension.

Ignition Interlock Device and Restricted Plates

Drivers reinstating their licenses after a DUI may be required to install an IID, which prevents the vehicle from starting if alcohol is detected on the driver’s breath. Additionally, Ohio may require the use of restricted yellow license plates, commonly known as “party plates,” for repeat offenders.

DUI and the Ohio Driver Point System

A DUI conviction adds six points to your driving record under the Ohio Driver Point System. Accumulating 12 or more points within two years results in a six-month license suspension.

Impact on License and Insurance

Following a DUI, you will need to provide proof of insurance (SR-22) to reinstate your license, which often leads to significantly increased insurance premiums. The Ohio Bureau of Motor Vehicles (BMV) will manage your suspension and reinstatement processes, and you can review fee structures on the Ohio DMV Fees and Charges Breakdown.
