ID CDL General Knowledge case studies
ID CDL General Knowledge · Put your knowledge to work in context.
A Commercial Driver's License (CDL) is a State-issued credential that allows a driver to operate a Commercial Motor Vehicle (CMV). FMCSA, the federal agency behind the CDL program, states plainly that it does not issue CDLs - State governments do. Most drivers obtain their CDL through their home State, and holding a license from more than one State is illegal. The CDL exists because driving a CMV demands a higher level of knowledge, experience, skills, and physical abilities than driving a non-commercial vehicle, so applicants must pass both skills and knowledge testing geared to those higher standards. The ID CDL General Knowledge case studies are 5 cases and about 2,651 words.
