Commercial Driver's License in a NutshellFederal law requires uniform licensing of truck and bus drivers (commercial drivers licenses [CDL]) in all states and the District of Columbia.
CDL testing and issuance began in Iowa Nov. 1, 1990. A person applying for a license to operate a commercial motor vehicle must apply for a CDL.
Commercial Driver License ManualThis manual provides driver license testing information for drivers who wish to have a CDL. This manual does NOT provide information on all the federal and state requirements needed before you can drive a commercial motor vehicle (CMV). You may have to contact your state driver licensing authority for additional information.
