§ 4.23. Operating under the influence of alcohol or drugs
(a) Operating or being in actual physical control of a motor vehicle is prohibited while:
(1) Under the influence of alcohol, or a drug, or drugs, or any combination thereof, to a degree that renders the operator incapable of safe operation; or
(2) 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 motor 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.

§ 634.34. Blood alcohol concentration standards
(a) Administrative revocation of driving privileges and other enforcement measures will be applied uniformly to offenders driving under the influence of alcohol or drugs. When a person is tested under the implied consent provisions of § 634.8, the results of the test will be evaluated as follows:
(1) If the percentage of alcohol in the person's blood is less than 0.05 percent, presume the person is not under the influence of alcohol.
(2) If the percentage is 0.05 but less than 0.08, presume the person may be impaired. This standard may be considered with other competent evidence in determining whether the person was under the influence of alcohol.
(3) If the percentage is 0.08 or more, or if tests reflect the presence of illegal drugs, the person was driving while intoxicated.
(b) Percentages in paragraph (a) of this section are percent of weight by volume of alcohol in the blood based on grams of alcohol per 100 milliliters of blood. These presumptions will be considered with other evidence in determining intoxication.

(b)(1) For purposes of subsection (a), the applicable limit on the alcohol concentration in a person's blood or breath is as follows:
(A) In the case of the operation or control of a vehicle, aircraft, or vessel in the United States, such limit is the lesser of—
(i) the blood alcohol content limit under the law of the State in which the conduct occurred, except as may be provided under paragraph (2) for conduct on a military installation that is in more than one State; or
(ii) the blood alcohol content limit specified in paragraph (3).
(B) In the case of the operation or control of a vehicle, aircraft, or vessel outside the United States, the applicable blood alcohol content limit is the blood alcohol content limit specified in paragraph (3) or such lower limit as the Secretary of Defense may by regulation prescribe.
(2) In the case of a military installation that is in more than one State, if those States have different blood alcohol content limits under their respective State laws, the Secretary may select one such blood alcohol content limit to apply uniformly on that installation.
(3) For purposes of paragraph (1), the blood alcohol content limit with respect to alcohol concentration in a person's blood is 0.10 grams of alcohol per 100 milliliters of blood and with respect to alcohol concentration in a person's breath is 0.10 grams of alcohol per 210 liters of breath, as shown by chemical analysis.
(4) In this subsection:
(A) The term “blood alcohol content limit” means the amount of alcohol concentration in a person's blood or breath at which operation or control of a vehicle, aircraft, or vessel is prohibited.
(B) The term “United States” includes the District of Columbia, the Commonwealth of Puerto Rico, the Virgin Islands, Guam, and American Samoa and the term “State” includes each of those jurisdictions.

§ 163. Safety incentives to prevent operation of motor vehicles by intoxicated persons
(a) General Authority.—The Secretary shall make a grant, in accordance with this section, to any State that has enacted and is enforcing a law that provides that any person with a blood alcohol concentration of 0.08 percent or greater while operating a motor vehicle in the State shall be deemed to have committed a per se offense of driving while intoxicated (or an equivalent per se offense).
(b) Grants.—For each fiscal year, funds authorized to carry out this section shall be apportioned to each State that has enacted and is enforcing a law meeting the requirements of subsection (a) in an amount determined by multiplying—
(1) the amount authorized to carry out this section for the fiscal year; by
(2) the ratio that the amount of funds apportioned to each such State under section 402 for such fiscal year bears to the total amount of funds apportioned to all such States under section 402 for such fiscal year.
(c) Use of Grants.—A State may obligate funds apportioned under subsection (b) for any project eligible for assistance under this title.
(d) Federal Share.—The Federal share of the cost of a project funded under this section shall be 100 percent.
(1) In general.—On October 1, 2003, and October 1 of each fiscal year thereafter, if a State has not enacted or is not enforcing a law described in subsection (a), the Secretary shall withhold from amounts apportioned to the State on that date under each of paragraphs (1), (3), and (4) of section 104(b) an amount equal to the amount specified in paragraph (2).
(2) Amount to be withheld.—If a State is subject to a penalty under paragraph (1), the Secretary shall withhold for a fiscal year from the apportionments of the State described in paragraph (1) an amount equal to a percentage of the funds apportioned to the State under paragraphs (1), (3), and (4) of section 104(b) for fiscal year 2003. The percentage shall be as follows:
(A) For fiscal year 2004, 2 percent.
(B) For fiscal year 2005, 4 percent.
(C) For fiscal year 2006, 6 percent.
(D) For fiscal year 2007, and each fiscal year thereafter, 8 percent.
(3) Failure to comply.—If, within 4 years from the date that an apportionment for a State is withheld in accordance with this subsection, the Secretary determines that the State has enacted and is enforcing a law described in subsection (a), the apportionment of the State shall be increased by an amount equal to the amount withheld. If, at the end of such 4-year period, any State has not enacted or is not enforcing a law described in subsection (a) any amounts so withheld from such State shall lapse.
