A QH inquiry allows agencies to check for the existence of what type of record?

The correct answer is based on the specific purpose of a QH inquiry, which is designed to allow law enforcement agencies to check for the existence of a criminal history record for individuals. This inquiry provides a quick way to see if someone has a criminal background, including felony convictions, misdemeanor arrests, and other criminal activities that have been documented in a state or national database.

Criminal history checks are crucial for various law enforcement and investigative purposes, especially when determining the background of a suspect or individual involved in a 911 call. The QH inquiry ensures that agencies have access to critical information that can influence their responses and decisions.

The other choices pertain to different types of records that are not covered by a QH inquiry. Traffic violations concern infractions committed while operating a vehicle and driving records refer specifically to a person's history as a driver, including licenses and accidents. Civil litigation records relate to legal conflicts that are settled in civil court, which is not the focus of a criminal history inquiry. Thus, the nature and intent of a QH inquiry specifically aligns with confirming criminal histories.
