An Enhanced Drivers License (EDL) is a state-issued drivers license that provides proof of identity and U.S. citizenship when crossing the U.S. border in a vehicle. It is issued in a secure process and includes technology that makes travel easier. EDLs are a low-cost, convenient option for entering the United States from Canada, Mexico, or the Caribbean through a land or sea port of entry, in addition to serving as a permit to drive. An EDL is a combined drivers license and passport card, meaning it allows for international land and sea travel, but not air travel, to countries that recognize it. EDLs are available in some states in the United States, including Michigan, Minnesota, New York, Vermont, and Washington.

EDLs are compliant with the Western Hemisphere Travel Initiative (WHTI), which is a U.S. law that requires all travelers, including U.S. citizens, to present a valid passport or other approved document when entering the United States from Canada, Mexico, or the Caribbean. As a WHTI-compliant travel document, an EDL may be used for "official purposes" covered by the U.S. REAL ID Act, such as boarding a domestic flight. However, a U.S. state that issues only EDLs, but does not issue any other REAL ID-compliant drivers license, is not deemed compliant with the REAL ID Act unless granted an extension.

In summary, an EDL is a state-issued drivers license that provides proof of identity and U.S. citizenship when crossing the U.S. border in a vehicle. It is a low-cost, convenient option for entering the United States from Canada, Mexico, or the Caribbean through a land or sea port of entry, in addition to serving as a permit to drive.
