While the vast majority of offenses for driving under the influence of alcohol or drugs (DUI) are filed and heard in state courts, DUI may also be charged as a federal offense. Most commonly, federal DUI charges arise in situations where the offender is stopped on the property of a federal military installation, national park, national monument, post office or on other federal property.
DUI on National Park Service land
If the DUI occurred on land controlled by the National Park Service, the DUI may be prosecuted as a Class B misdemeanor punishable by up to 6-months incarceration, a $5,000.00 fine and 5-years of probation. Additionally, a refusal of testing is considered a criminal offense with punishment of up to one-year incarceration, a fine and the suspension of driving privileges on federal land or property for a period of up to one-year.
