PRPA DUI Practice Test

A person with an alcohol concentration of 0.04 or more who is driving a commercial vehicle falls under ARS 28-1381A.4. This specific section addresses the legal implications for commercial drivers and sets the threshold for blood alcohol concentration (BAC) at a lower level than that for non-commercial drivers, reflecting the increased responsibility and safety requirements associated with operating larger vehicles.

The law recognizes that commercial drivers are held to stricter standards due to the potential hazards that come with driving a commercial vehicle, which can weigh significantly more and pose greater risks to public safety if the driver is impaired. Therefore, the 0.04 BAC limit is a clear statute aiming to enforce safety and accountability on the roads.

Other sections outlined in the choices relate to general DUI regulations, but ARS 28-1381A.4 specifically targets those operating commercial vehicles, clearly differentiating the standard for that category of driver.
