Ohio CDL Manual and Test Resources

The Ohio Commercial Driver License Manual is the primary study source for Ohio CDL applicants. It covers commercial licensing, safe driving, cargo, air brakes, combination vehicles, endorsements, vehicle inspection, basic control skills, and road testing.

CDL Mastery can help you organize and practice the material, but the current Ohio CDL manual and official Ohio BMV instructions should remain your final authority.

Current eligibility documentation First-time Ohio CDL applicants must provide qualifying proof of United States citizenship or lawful permanent residency. Review the current Ohio BMV document list before visiting a testing or licensing location.

Official Ohio CDL manual

Ohio BMV publishes the Commercial Driver License Manual as form HSY 7605. A Spanish edition is also available as HSY 7606.

A first Class A CDL.
A first Class B CDL.
A Class B-to-Class A upgrade.
A first passenger endorsement.
A first school bus endorsement.

Ohio CDL medical certification

Ohio CLP applicants and CDL holders must self-certify the type of commercial driving they perform or expect to perform.

The four self-certification categories are:

Non-excepted interstate.
Excepted interstate.
Non-excepted intrastate.
Excepted intrastate.

Drivers in a non-excepted category generally must maintain a valid medical certification when required by federal or Ohio rules.

Effective June 23, 2025, certified medical examiners began transmitting commercial-driver examination results electronically through the FMCSA National Registry to Ohio BMV.

Paper medical cards generally are not required Ohio CDL and CLP holders generally no longer need to fax, mail, or personally deliver routine DOT medical cards when the examiner has transmitted the result electronically. Confirm that your Ohio record updates correctly after the examination.

Failure to maintain required medical certification or self-certification can prevent issuance, renewal, transfer, or upgrade of commercial privileges and may lead to a CDL downgrade.

Ohio CDL skills test

Ohio’s CDL skills test consists of three parts.

Pre-trip inspection: Identifying safety-critical components and explaining the condition being checked. Ohio currently lists a 30-minute time limit.
Basic maneuverability: Completing required low-speed control and backing exercises. Ohio currently lists a 40-minute time limit.
Road test: Demonstrating safe commercial driving in traffic and roadway situations.

Applicants must provide a vehicle appropriate for the requested CDL class and endorsements.

Passenger applicants must provide an appropriate bus designed to transport at least 16 people, including the driver, when required for the endorsement test.

Retesting after a failure Ohio requires an applicant who fails any portion of the CDL skills test to wait two days before retesting.

Ohio CDL skills-test fees

At an Ohio state-owned testing facility, applicants must first purchase the required CDL Test Receipt from a deputy registrar license agency.

Ohio currently lists these state-facility testing fees:

Pre-trip inspection: $10.
Basic maneuverability test: $10.
Road test: $30.

Third-party testing facilities establish their own fees, which may be different from state-owned facility fees.

Ohio CDL skills-test locations

CDL skills testing is available by appointment through state-owned and approved third-party testing locations.

Third-party providers may offer testing vehicles for rent, but availability and fees vary. Confirm the vehicle, appointment, payment, and documentation requirements directly with the location.

Representative vehicle and restrictions

The vehicle used during the Ohio CDL skills test can affect the restrictions placed on the final license.

Testing without a full air-brake system may result in an air-brake restriction.
Testing in an automatic-transmission vehicle may result in a manual-transmission restriction.
Testing in a Class A vehicle that is not a tractor-trailer may result in a tractor-trailer restriction.
Passenger and school bus applicants must use an appropriate representative vehicle.

Applicants should test in equipment matching the commercial vehicle they expect to operate whenever possible.

Ohio CDL endorsements

Common Ohio CDL endorsements include:

T: Double and triple trailers.
P: Passenger vehicles.

Pass the Ohio HazMat knowledge test.
Provide required identity and lawful-status documentation.

Out-of-state CDL applicants

Drivers with an unexpired out-of-state CDL may apply to transfer their commercial privileges to Ohio by presenting the required identity, citizenship or residency, Social Security, Ohio address, medical, and self-certification documentation.

How to study the Ohio CDL manual

Choose the correct CDL class. Determine whether you need Class A, B, or C.
Identify every endorsement. List HazMat, Tank, Passenger, School Bus, or Doubles and Triples.
Study General Knowledge first. Build your foundation in inspections, speed, space, hazards, and emergencies.
Add Air Brakes when applicable. Learn system components, pressure rules, warning devices, leakage limits, and inspection steps.
Add Combination Vehicles for Class A. Focus on coupling, trailer air systems, rollover prevention, off-tracking, and inspections.
Study endorsements separately. Keep HazMat, Tank, Passenger, School Bus, and Doubles and Triples in focused sessions.
Practice by topic. Use missed questions to identify the exact manual section that needs review.
Prepare separately for skills testing. Practice the pre-trip inspection aloud, basic maneuverability, and safe road-test habits in a representative vehicle.
