To operate a commercial motor vehicle in Ohio, it is essential to possess a valid Commercial Driver's License (CDL). This license ensures that a driver has undergone the necessary training and testing to meet the specific skills required for operating larger and more complex vehicles safely. Alongside having a CDL, compliance with vehicle weight and size regulations is crucial.
