  • While under the influence of alcohol; or
  • With an alcohol concentration of .08 or above (0.04 percent for commercial licensees) - Illegal Per Se; or

NRS 484C.430: DUI proximately causing death or substantial bodily harm (discussed further below).

The Nevada Supreme Court has set forth criteria for determining whether a person is in “actual physical control” of a vehicle. See Isom v. State, 105 Nev. 230, 773 P.2d 1226 (1989); Rogers v. State, 105 Nev. 391, 773 P.2d 543 (1989). The Nevada Supreme Court has defined “under the influence” to mean a person has ingested a substance to a degree that renders him incapable driving or exercising actual physical control. See Cotter v. State, 103 Nev. 303, 738 P.2d 506 (1987).
