The Interstate Driver License Compact (IDLC) was created by the National Conference of Commissioners on Uniform State Laws in
The IDLC applies only to drivers who hold valid licenses issued by one member state and who travel through another member state while operating a motor vehicle. If a person drives without a license, he or she will be subject to arrest and prosecution in any state where he or she is stopped.
The IDLC also requires each state to enact legislation allowing law enforcement officers to suspend the driver's license of an individual who has been arrested for driving under the influence (DUI) of alcohol or drugs. In addition, the IDLC requires each state's Department of Motor Vehicles to cooperate with the departments of other states to ensure that suspended licenses are revoked as quickly as possible.
The IDLC was adopted by Congress in 1966. It provides a means for states to exchange information regarding drivers who have lost their licenses because of arrests or convictions for drunk driving. The IDLC allows states to share information about individuals who have lost their licenses for reasons such as failure to pay fines or fees, refusal to submit to chemical testing, or failure to attend court hearings.
If an individual loses his or her license in one state due to a conviction for drunk driving, then he or she must notify the authorities in any other state where he or she intends to drive. This includes states that are party to the compact.
States that are part of the compact must report certain information to each other when a driver is arrested or convicted of a non-DUI offense. These reports include whether the arrest was made by local police or state troopers, what type of offense was committed, and how many times the offender had previously been arrested or convicted of a similar offense.
