Ohio CDL permit test locations and steps

A commercial driver’s license (CDL) has its own manual, tests and test sites. The Ohio CDL permit test locations are the Driver Exam Stations of the Bureau of Motor Vehicles (BMV), where you test in person, and the skills test that follows happens at a separate CDL skills testing location.

Where are the Ohio CDL permit test locations?

At any Driver Exam Station, in person. The CDL test can’t be taken online.

How to study for the Ohio CDL permit test

There’s a knowledge test for each class of vehicle, each endorsement and the air brake restriction, so study the parts that match the license you want. The BMV points you to the Ohio Commercial Driver License Manual (HSY 7605), which also comes in Spanish (HSY 7606). Its CDL page doesn’t give the number of questions or a CDL sample test.

Who can apply

First-time applicants must:

  • Be at least 18 and hold a valid Ohio driver’s license
  • Have a valid U.S. Social Security number
  • Prove U.S. citizenship or lawful permanent residency
  • Pass a vision test, or meet the federal physical qualifications
  • Read, speak and write English well enough to talk with the public, understand highway signs and fill in reports (a federal rule; translation aids aren’t allowed)

Under 21, you’re limited to driving commercial vehicles within Ohio.

From learner’s permit to license

After the knowledge tests:

  1. Buy a Commercial Learner’s Permit (CLP) at a deputy registrar and self-certify the type of driving you’ll do. It’s valid for 12 months, and you drive only with a CDL holder endorsed for the vehicle.
  2. Finish Entry Level Driver Training (ELDT) for the class and endorsement on your permit, or prove you’re exempt, before you schedule the skills test.
  3. Pass the skills test at a CDL skills testing location: a pre-trip inspection (30 minutes), a basic maneuverability test (40 minutes) and a road test, in a vehicle you provide for the class.
  4. Buy your CDL at a deputy registrar before the permit expires.

If you fail any part of the skills test, you wait two days to retest. A hazmat endorsement also needs a Transportation Security Administration (TSA) threat assessment.
