Final answer:
The state of Utah prohibits driving a motor vehicle with a BAC of 0.08% or above.
Step-by-step explanation:
In the state of Utah, it is currently prohibited to drive a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or above.
This means that if a person's BAC is 0.08% or higher, they can be charged with driving under the influence (DUI).
However, laws can change, and it's essential to verify the most recent information from an authoritative source, such as the Utah Department of Public Safety or the state's official legal resources, to ensure accuracy and compliance with current regulations.
