Missouri's statute, Mo. Rev. Stat. § 577.012, provides that a person commits the offense of driving with excessive blood alcohol content by operating a vehicle, or a commercial motor vehicle, while having alcohol in his or her blood at or above the level the statute sets for that kind of vehicle. Missouri's statute provides that this content may be shown by chemical analysis of the person's blood, breath, saliva or urine, with the test conducted under other Missouri sections.

Nebraska's statute, Neb. Rev. Stat. § 60-6,196, makes it unlawful to operate or be in the actual physical control of any motor vehicle while under the influence of alcoholic liquor or of any drug, or while having an alcohol concentration at or above a level the statute sets, stated separately for blood and for breath. Nebraska's statute provides that a person who does so is guilty of a crime.

Virginia's statute, Va. Code § 18.2-266, makes it unlawful to drive or operate any motor vehicle, engine or train while the person has a blood or breath alcohol concentration at or above the level the statute sets, as indicated by a chemical test administered as provided in the same article of Virginia law. Virginia's statute lists that concentration ground among several alternative clauses and provides that a charge alleging a violation of the section shall support a conviction under any of those clauses.

Montana's statute, Mont. Code Ann. § 61-8-1002, includes among the grounds for driving under the influence driving or being in actual physical control of a noncommercial vehicle upon the ways of this state open to the public while the person's alcohol concentration is at or above a level the statute sets. Montana's statute sets a different level for a commercial motor vehicle within the state, with the concentration in each case as shown by analysis of the person's blood, breath, oral fluid, or other bodily substance.

Montana's statute, Mont. Code Ann. § 61-8-1002, imposes absolute liability for a violation, as provided in a separate Montana section.

Arkansas's statute, A.C.A. § 5-65-103, makes it unlawful to operate or be in actual physical control of a motorboat on the waters of the state or a motor vehicle if at that time the alcohol concentration in the person's breath or blood was at or above the level the statute sets, based on a definition of alcohol concentration in a separate Arkansas section. Arkansas's statute separately makes the same conduct unlawful for a person who is intoxicated, and provides that an alcohol-related offense under the section is a strict liability offense.

Deadlines, limits and penalty ranges are set by each state’s statutes, so this page does not state them. Each state page shows them with the official source and the date they were verified — or says plainly that a figure has not been confirmed yet.
