Which system allows law enforcement agencies access to North Carolina driver's digital photographs and signatures?

The correct answer is the DMV, as it is the agency responsible for maintaining driver and vehicle records, including digital photographs and signatures of drivers in North Carolina. This system enables law enforcement agencies to access crucial information that can assist in various law enforcement functions, such as identity verification and the investigation of cases.

The DMV's database is specifically designed to facilitate easy and secure access for authorized users, including law enforcement personnel, ensuring that they can retrieve the necessary information effectively during their operations. Other systems mentioned, like NCIS, FBI-TECS, and ACIC, may serve different purposes related to broader criminal justice or national security functions, but do not specifically provide access to North Carolina driver's digital photographs and signatures.
