What is CDL? Why do you require it?

A Commercial Driver's License (CDL) is required to operate commercial vehicles. Any driver operating commercial driving equipment or other sorts of heavy machinery will need this licence. A higher level of expertise and understanding is required to operate a commercial motor vehicle. To be authorised to drive any form of motor vehicle on public roads, most drivers must receive a commercial driver's licence (CDL) from their home state. Applicants must pass both skills and knowledge tests in order to pass the Commercial Driver's License test. The CDL permit test requirement is generally based on national laws, however each state may impose additional limits. The applicant's age, driving record, physical and mental health are all important considerations.
