What is the function of the Texas Department of Public Safety's Criminal Investigation Division?

The role of the Texas Department of Public Safety's Criminal Investigation Division is primarily focused on investigating criminal activities and enforcing laws. This division is dedicated to addressing serious offenses such as homicides, drug trafficking, organized crime, and human trafficking, among others. By conducting thorough investigations, gathering evidence, and working with various other law enforcement agencies, the division helps to uphold public safety and ensure that justice is served.

The other functions listed pertain to different divisions or areas of focus within the Texas Department of Public Safety, such as traffic safety programs, which aim to improve road safety and reduce accidents. Managing state park safety is related to environmental and recreational safety rather than criminal investigations, and supervising vehicle registrations is a function associated with the administration of motor vehicle laws rather than law enforcement activities. Thus, the focus of the Criminal Investigation Division distinctly aligns with the investigation and enforcement of criminal laws, making this choice the correct answer.
