Answer:
state law enforcement agencies
Explanation:
Law enforcement agencies are US government institutions whose primary purpose is to participate in a criminal justice system where they investigate and patrol crimes and violations of laws. These agencies may be federal, local, and state agencies. The so-called state law enforcement agencies investigate incidents, accidents, crimes and legal violations throughout the territory of a given state. For this reason, we can say that if Larry's main duties include investigating accidents that occur on state roads and highways, he works for a state law enforcement agency.
