This is the law enforcement division of the Arkansas Department of Transportation. They deal primarily with commercial motor vehicle enforcement, including operation of the weigh and inspection stations throughout the state. Public calls for service ring at the Arkansas Highway Police Headquarters in Little Rock but, because of the AHP’s mission and structure, there aren’t many calls from the public. Most requests for service come from other law enforcement agencies. AHP District 5 consists of ARDOT District 1 (Crittenden, Cross, Lee, Monroe, Phillips, St. Francis, and Woodruff counties) and ARDOT District 10 (Clay, Craighead, Greene, Lawrence, Mississippi, Poinsett, and Randolph counties).

Radio traffic follows the Arkansas State Police standard 10 codes and phonetic alphabet.

The communications center answers to “Little Rock,” “Little Rock Central,” or “D5 Little Rock.” Highway Police Officers assigned to District 5 use 500 or 5000 series callsigns, depending on their assignment.
