This section outlines training and standards applicable to drivers holding a Commercial Driver’s License (CDL).
Part 383 establishes standards to help prevent truck and bus accidents, fatalities, and injuries by requiring drivers to have a single CDL, and by disqualifying drivers who operate commercial motor vehicles (CMVs) in an unsafe manner. With certain limited exceptions listed in 49 CFR 383.3, a driver must hold a CDL if he or she operates in interstate, intrastate, or foreign commerce and drives a CMV as defined in 49 CFR 383.5. A commercial learner’s permit (CLP) is also considered a valid CDL for the purpose of behind-the-wheel training. The complete list of CLP requirements are in 49 CFR 383.25.
CDLs are State-issued Licenses.
Because the CDL is a State-issued license, carriers should check with the appropriate State officials regarding particular license classes and specific exceptions stated in 49 CFR 383.3.
The Commercial Driver’s License Information System (CDLIS) enables States to exchange information about the driving records of CMV drivers. CDLIS helps ensure that only one license is issued to a driver, and that currently disqualified drivers cannot obtain a CDL. Employers can access information in the CDLIS clearinghouse through their State’s vehicle licensing agency.
