The AAMVA Conviction/Withdrawal Code Dictionary (ACD)

The ACD Codes — A Key Component to Understanding Driving Records

When viewing state MVRs one can readily see that each state has unique conviction reporting language and codes inherent to their motor vehicle statutes and specific violation language. States must communicate with one another and with the National Driver Register (NDR) regarding commercial drivers, problem drivers, and out-of state actions, although to varying extent. The question is—how do states know what the conviction codes from other states mean and how do they translate this information into their own language and code set?

The answer is the states utilize the AAMVA Code Dictionary (ACD) as a translation table.

The AAMVA Code Dictionary (ACD) is a translation table used to exchange conviction and withdrawal information between the states’ driver licensing authorities. The AAMVA Code Dictionary (ACD) is copyrighted by the American Association of Motor Vehicle Administrators (AAMVA).

A primary function of the ACD is to enable the state to use the Commercial Driver's License Information System (CDLIS) to exchange convictions and withdrawals. Other applications, such as the Problem Driver Pointer System (PDPS), use these codes as well. Also, many states use the ACD to indicate out-of-state convictions on driving records.

ACD Codes Affect Today’s Driving Records

Thus in practice, the ACD Code System is used to exchange conviction and withdrawal information between the states' driver licensing authorities. But many states have adopted some or all of the codes into their own code system. Thus many states show ACD Codes on their driving records. So, knowing what a specific ACD Code means can be a helpful indication of what a state's lingo for an MVR conviction or action means. Plus the knowledge of what a specific ACD Code means can be a very helpful indication when deciphering the meaning of a conviction or withdrawal action.
