32 CFR 234.17 - Vehicles and traffic safety.
(a) In general. Unless specifically addressed by regulations in this part, traffic and the use of vehicles within the Pentagon Reservation are governed by State law. Violating a provision of State law is prohibited.
(b) Open container of an alcoholic beverage.
(1) Each person within a vehicle is responsible for complying with the provisions of this section that pertain to carrying an open container. The operator of a vehicle is the person responsible for complying with the provisions of this section that pertain to the storage of an open container.
(2) Carrying or storing a bottle, can, or other receptacle containing an alcoholic beverage that is open or has been opened, or whose seal is broken, or the contents of which have been partially removed, within a vehicle on the Pentagon Reservation is prohibited.
(3) This section does not apply to:
(i) An open container stored in the trunk of a vehicle or, if a vehicle is not equipped with a trunk, an open container stored in some other portion of the vehicle designed for the storage of luggage and not normally occupied by or readily accessible to the operator or passengers; or
(ii) An open container stored in the living quarters of a motor home or camper.
(c) Operating under the influence of alcohol, drugs, or controlled substances.
(1) Operating or being in actual physical control of a vehicle is prohibited while:
(i) Under the influence of alcohol, a drug or drugs, a controlled substance or controlled substances, or any combination thereof, to a degree that renders the operator incapable of safe operation; or
(ii) The alcohol concentration in the operator's blood or breath is 0.08 grams or more of alcohol per 100 milliliters of blood or 0.08 grams or more of alcohol per 210 liters of breath. Provided, however, that if State law that applies to operating a vehicle while under the influence of alcohol establishes more restrictive limits of alcohol concentration in the operator's blood or breath, those limits supersede the limits specified in this paragraph.
(i) At the request or direction of an authorized person who has probable cause to believe that an operator of a vehicle within the Pentagon Reservation has violated a provision of paragraph (c)(1) of this section, the operator shall submit to one or more tests of the blood, breath, saliva, or urine for the purpose of determining blood alcohol, drug, and controlled substance content.
(iii) Any test or tests for the presence of alcohol, drugs, and controlled substances shall be determined by and administered at the direction of an authorized person.
(iv) Any test shall be conducted by using accepted scientific methods and equipment of proven accuracy and reliability operated by personnel certified in its use.
(4) Presumptive levels.
(i) The results of chemical or other quantitative tests are intended to supplement the elements of probable cause used as the basis for the arrest of an operator charged with a violation of this section. If the alcohol concentration in the operator's blood or breath at the time of the testing is less than the alcohol concentration specified in paragraph (c)(1)(ii) of this section, this fact does not give rise to any presumption that the operator is or is not under the influence of alcohol.
(ii) The provisions of paragraphs (c)(3) and (c)(4)(i) of this section are not intended to limit the introduction of any other competent evidence bearing upon the question of whether the operator, at the time of the alleged violation, was under the influence of alcohol, a drug or drugs, or a controlled substance or controlled substances, or any combination thereof.
