Frequently Asked Questions

If you are 15 ½, you can get a TIPIC (temporary instruction permit identification card) within 60 days of passing the knowledge and vision tests. After holding the permit for six months and completing your driving instruction, you can apply for a probationary license within 60 days after passing the driving and skills tests. If you're 18 or older, after obtaining the permit, you can obtain a class D driver license without the six-month waiting period.

You have two options:
  • You can visit an Ohio driver exam office. No appointment is required, but check days and business hours of the chosen office.
  • You can take the test online at KnowTo Drive, the official knowledge testing platform. If you are between 15 ½ and 19 years old, you must be supervised by a driver who is at least 19 years old. After passing the test, you are still required to visit a local Ohio BMV office to validate your identity and pass the vision screening.

Applicants can choose between a compliant and a standard license. Ensure you have proof for the following based on your card preference:
  • Full legal name (and proof of name change, if applicable)
  • Date of birth
  • Legal presence in the U.S.
  • Social Security number (SSN)
  • Ohio street address (you'll need two documents for a compliant card and one document for a standard card)

Refer to the acceptable documents list for more information.

With a permit in Ohio, the following restrictions apply:
  • You must have your permit while driving.
  • If you are under 16, a parent/guardian, or a licensed driving instructor must be in the passenger seat. If you are 16 or older, driving is allowed with any licensed driver over 21 in the passenger seat, except between midnight and 6 a.m. During this time you must be accompanied by a parent, guardian, custodian, or an approved driver aged 21 years or older (form BMV 2438).
  • Everyone in the vehicle must use safety belts.

With a probationary license, these restrictions apply:
  • Driving is prohibited from midnight to 6 a.m., unless accompanied by a parent, guardian, or custodian, or an approved driver aged 21 years or older. Exceptions for driving during restricted hours include employment activities and school-sponsored or religious events (form BMV 2826).
  • You can transport only one non-family member unless accompanied by a parent or guardian.
  • Everyone in the vehicle must use safety belts.
  • The driver is prohibited from using any mobile devices, including cellular phones.

In Ohio, an instruction permit is valid for a period of one year. If you are under 18, use this time to complete a driver education class (24 hours of instruction and 8 hours of driving time) at a training school and accumulate 50 hours of driving before scheduling the road test to obtain a probationary driver license.

If you don't pass your BMV written test, you'll need to wait for 24 hours before attempting it again. There's no restriction on the number of retests available in person. However, if you opt for the online permit test, you're allowed a maximum of two attempts within a six-month period.
