Illegal Per Se Law defines offense at BAC level...

• A. Makes it an offense to drive with BAC at or above .08
• B. Does not replace DUI law, but works with it
• C. Sets a zero BAC for all drivers
• D. Applies only to commercial drivers

Answer: (A)

Per se laws establish an offense based solely on a specific blood alcohol concentration, regardless of observed impairment. In practice, this means someone is committing a DUI offense as soon as their BAC reaches or exceeds a defined threshold. The most common standard for non-commercial drivers is 0.08 percent, which is why the statement about driving with BAC at or above 0.08 being illegal best captures the concept. This does not imply a universal zero BAC for everyone, and it isn’t limited to commercial drivers (though commercial drivers often have a lower limit, such as 0.04). It also doesn’t say that per se replaces all DUI provisions; rather, per se is one way DUI offenses can be prosecuted, alongside impairment-based rules.
