32 CFR § 634.8 - Implied consent.
(a) Implied consent to blood, breath, or urine tests. Persons who drive on the installation shall be deemed to have given their consent to evidential tests for alcohol or other drug content of their blood, breath, or urine when lawfully stopped, apprehended, or cited for any offense allegedly committed while driving or in physical control of a motor vehicle on military installations to determine the influence of intoxicants.
(b) Implied consent to impoundment. Any person granted the privilege to operate or register a motor vehicle on a military installation shall be deemed to have given his or her consent for the removal and temporary impoundment of the POV when it is parked illegally, or for unreasonable periods, as determined by the installation commander or applicable authority, interfering with military operations, creating a safety hazard, disabled by accident, left unattended in a restricted or controlled area, or abandoned. Such persons further agree to reimburse the United States for the cost of towing and storage should their motor vehicle be removed or impounded. Existence of these conditions will be determined by the installation commander or designee.
(c) Any person who operates, registers, or who is in control of a motor vehicle on a military installation involved in a motor vehicle or criminal infraction shall be informed that notice of the violation of law or regulation will be forwarded to the Department of Motor Vehicles (DMV) of the host state and/or home of record for the individual, and to the National Register, when applicable.
