Quick answer
Start with the CLP, medical certification, and the General Knowledge test
Most Ohio CDL applicants need a valid regular driver license, must be at least 18 for intrastate commercial driving or 21 for interstate operation, and must pass the required knowledge tests before the CDL skills test. The CLP must be held at least 14 days before skills testing.

Classes
CDL classes available in Ohio
Ohio follows the federal CDL class structure: Class A for qualifying combination vehicles, Class B for many single heavy vehicles, and Class C for certain passenger or hazardous-material vehicles below Class A/B thresholds. The class you apply for should match the vehicle you will test in and the commercial work you plan to do.
Ohio applicants should verify BMV fee schedules because permit, license, endorsement, renewal, and testing transactions are not one single fee.
