The driver with a blood alcohol concentration of .10 could potentially be arrested for DUI or DWI, but determining who to arrest in a car accident involving injuries is a complex process. The injured party may choose to pursue a personal injury lawsuit against the driver at fault.
Step-by-step explanation:
In this situation, the driver who had a blood alcohol concentration of .10 could potentially be arrested for driving under the influence (DUI) or driving while intoxicated (DWI) depending on the specific laws in the jurisdiction. However, it is important to note that determining who to arrest in a car accident involving injuries is a complex process and may require a thorough investigation by law enforcement officials.
In addition to the criminal charges, there might also be civil liability involved for the driver who caused the accident. The injured party may choose to pursue a personal injury lawsuit against the driver at fault to seek compensation for their medical expenses, pain and suffering, and other damages resulting from the accident.
