New Hampshire State Police Troop D - Concord, NH

Law Enforcement for the Capital Region

New Hampshire State Police Troop D, headquartered on Iron Works Road in Concord, serves as the primary state law enforcement presence for Merrimack County. This troop is strategically located near the interchange of Interstates 89 and 93, placing it at a vital nexus of the state's transportation network. Troop D is responsible for patrolling 25 towns and two cities in the central region of New Hampshire, providing 24-hour coverage to ensure public safety and enforce motor vehicle laws. The troopers assigned to this barracks act as the first responders for accidents and criminal incidents on the highways and in rural communities that may lack their own full-time police departments. Additionally, because the state capital falls within their jurisdiction, Troop D plays a crucial role in securing state properties, including the State House, the Governor's Mansion, and various government office complexes. Their work is characterized by a commitment to professionalism, integrity, and fairness in the application of the law.

Traffic Safety and Accident Investigation

A significant portion of Troop D's mission involves maintaining safety on the region's busy highways. Merrimack County sees a high volume of commuter and tourist traffic, particularly during peak seasons. Troopers conduct regular patrols to deter speeding, aggressive driving, and driving under the influence (DUI). They are highly trained in accident reconstruction and investigation, responding to serious collisions to determine causes and clear hazards from the roadway efficiently. The troop also utilizes specialized units, such as the Commercial Vehicle Enforcement Unit, to ensure that large trucks operating in the area comply with weight and safety regulations. By enforcing traffic laws and educating the public, Troop D works tirelessly to reduce fatalities and injuries on New Hampshire's roads.

• Highway Patrol: Monitoring I-93, I-89, and state routes for traffic violations.

Criminal Investigation and Community Services

Beyond traffic enforcement, Troop D is actively involved in criminal investigations. Troopers handle a wide array of cases, from property crimes and thefts to assaults and drug offenses. The barracks serves as a hub for processing evidence and coordinating with the Major Crime Unit for more serious felonies. The station on Iron Works Road is also a resource for the community, offering services such as fingerprinting for employment or licensing (by appointment), and serving as a location for sex offender registration compliance. Residents can also visit the station to request copies of accident reports or to report non-emergency incidents. Troop D works in close partnership with the Merrimack County Sheriff's Office and local municipal police to create a comprehensive safety net for the region. Their presence is a reassurance to the citizens of Merrimack County that help is always just a phone call away.
