Ohio (OH) CDL Practice Tests

Ohio (OH) CDL permit applicants can work through these five practice questions to review core exam concepts and prepare for the Commercial Learner’s Permit (CLP) knowledge test.

Ohio CDL Practice Tests: General Knowledge, Combination Vehicle & Air Brakes

Drivers preparing for an Ohio Commercial Driver’s License (CDL) should focus on three core CDL practice tests. These align with the written knowledge exams required in Ohio and support the material covered in the official Ohio CDL manual.

• General Knowledge CDL Practice Test
• Combination Vehicle CDL Practice Test
• Air Brakes CDL Practice Test

For best results, combine CDL practice tests with the Ohio Commercial Driver License Manual and focus on the sections that match your intended license class and endorsements.

Preparing for the Ohio CDL Exam

Commercial driver licensing standards are established at the federal level by the Federal Motor Carrier Safety Administration (FMCSA). Each state is responsible for administering CDL testing and licensing.

In Ohio, CDL information and testing requirements are published by the Ohio Bureau of Motor Vehicles (BMV) and the Ohio Department of Public Safety (DPS). The official CDL manual used for written and skills testing is:

• Ohio Commercial Driver License Manual (PDF)

The Ohio CDL manual applies to all commercial license classes, including:

• Class A CDL
• Class B CDL
• Class C CDL
