According to Arizona law, when is a person considered to be under the influence?

A person is considered to be under the influence in Arizona if they are impaired to the slightest degree. This standard emphasizes that impairment can occur even with low levels of alcohol consumption or the presence of drugs in the system. The law recognizes that any level of impairment can negatively affect a person’s ability to operate a vehicle safely, thus prioritizing public safety.

Other options reflect specific blood alcohol concentration (BAC) levels, such as .06 or .08, which do represent legal thresholds for intoxication under certain circumstances, especially concerning DUI laws. However, Arizona law also encompasses impairment that may not reach these levels but still affects a person's faculties. This broader definition allows law enforcement to take action in instances where a driver's capability is compromised, regardless of whether they exceed a specific BAC limit.
