The Berlin Police Department started a Traffic Safety Unit in 2001. This unit was formed with the expectation that officers assigned would get specialized training dealing with motor vehicle collisions. To become a collision re-constructionist, officers must undergo a minimum of 160 hours of training. The primary mission of the unit is to investigate all fatal and potentially fatal collisions occurring in the Town limits of Berlin. In 2004 the police department received a grant allowing it to purchase a Nikon DTM-332 total station and related software. This allows the investigator to measure and record to scale the scene and easily transfer it to a CAD program. The total station can also be used in the same fashion to record crime scenes. The policy of the Berlin Police Department is to assist all neighboring agencies, when requested, in the investigation of traffic or criminal matters using the total station.
