Commercial Driver's License Information System

Mandated by the Commercial Motor Vehicle Safety Act 1986 (CMVSA) and revised in accordance with various other federal laws subsequent to CMVSA, CDLIS helps document the issuance of a Commercial driver's license (CDL) and the withdrawal of a commercial driver by the State Driver Licensing Agencies (SDLAs) of the CDLIS jurisdictions (the 50 U.S. States and the District of Columbia). The purpose of CDLIS is to keep a record of each driver nationwide and help ensure only one driver license and one record for each driver and to enable authorized users nationwide, such as local law enforcement officials, to check whether a driver is withdrawn, through the cooperative exchange of commercial driver information between the CDLIS jurisdictions.

CDLIS has operated in all 51 CDLIS jurisdictions since April 1, 1992. As of February 25, 2013, CDLIS had 14.6 million driver records, growing at an average rate of nearly 40,000 new records per month.

The System

CDLIS consists of a Central Site (located in Ashburn, Virginia) and nodes for all 51 SDLAs, all interconnected on AAMVAnet (AAMVA's proprietary, secure network). The Central Site stores identification data about each commercial driver registered in the jurisdictions, such as: name; date of birth; last five digits of the Social Security Number; State driver license number and Also Known As (AKA) information (i.e., former/previous names, DOBs, and/or State driver license numbers). The information at the Central Site constitutes a driver's unique CDLIS Master Pointer Record (MPR). The jurisdiction nodes store the Driver History Records (DHRs), which include driver identification information, license information, history of convictions, and history of withdrawals for each commercial driver licensed by the particular state.

When a jurisdiction SDLA queries the CDLIS Central Site via AAMVAnet to obtain information about an applicant prior to issuing a CDL, the CDLIS Central Site compares data provided by the State Of Inquiry (SOI) against all MPRs at the Central Site. If one or more matches are returned, then the CDLIS Central Site "points" the SOI to the State Of Record (SOR), where more detailed information about the driver's commercial driving history is found. When a jurisdiction convicts or withdraws an out-of-state commercial driver, the State of Conviction (SOC) or State of Withdrawal(SOW) transmits the relevant conviction or withdrawal information via AAMVAnet to the driver's SOR.

Maintenance Fees

CDLIS maintenance fees cover the cost of the Central Site support and maintenance, AAMVAnet leased line services and support, Network Control Software, the AAMVA help desk, AAMVA's CDLIS development and testing, and AAMVA's CDLIS staff and contractors.

AAMVA's CDLIS maintenance fee, charged to each state, is $1 per year for each CDL record on CDLIS owned by the particular state.

American Association of Motor Vehicle Administrators

The American Association of Motor Vehicle Administrators (AAMVA) is a non-governmental, voluntary, tax-exempt, nonprofit educational association. AAMVA is a private corporation which strives to develop model programs in motor vehicle administration, police traffic services, and highway safety.

The association serves as an information clearinghouse for these same disciplines, and acts as the international spokesperson for these interests. The association is composed of motor vehicle and law enforcement administrators and executives from all 50 states, the District of Columbia, and Canadian territories and provinces. Although Canadian jurisdictions are members of AAMVA, Canada also has a distinctly separate but similar organization, the Canadian Council of Motor Transport Administrators (CCMTA), which more directly establishes governance of driver & vehicle matters for provinces and territories. At least two Mexican states have been AAMVA members at some time. The U.S. Virgin Islands are current members of AAMVA as well as the District of Columbia.

The association is divided into four separate regions, primarily by geography, encompassing all North American members. Each region holds annual meetings with the entire membership meeting once per year. Within the membership are committees and task forces which meet typically on a quarterly basis.

Commercial driver's license

A commercial driver's license is a driver's license required to operate large, heavy, or placarded hazardous material vehicles in commerce.

Motor vehicle declared out of service

A motor vehicle is declared in the United States as out of service by personnel authorized to perform inspections of commercial motor vehicles and are designated as Special Agents of the Federal Motor Carrier Safety Administration. These authorized personnel are by law able to enter upon and perform inspections of any and all Commercial Motor Vehicles in operation.

An inspection report named Form MCS 63 is a Driver Equipment Compliance Check, and shall be used to record findings from a motor vehicle selected for inspection.

Traffic stop

A traffic stop, commonly called being pulled over, is a temporary detention of a driver of a vehicle by police to investigate a possible crime or minor violation of law.

Traffic violations reciprocity

Under traffic violations reciprocity agreements, non-resident drivers are treated like residents when they are stopped for a traffic offense that occurs in another jurisdiction. They also ensure that punishments such as penalty points on one's license and the ensuing increase in insurance premiums follow the driver home. The general principle of such interstate, interprovincial, and/or international compacts is to guarantee the rule "one license, one record."
