The road accident investigation teams are in charge of the practical implementation of road and off-road traffic accident investigations. The investigation teams have expert representation from the police, the fields of medicine, vehicle technology, road maintenance and behavioural sciences, and other special branches as required.
There are 20 investigation teams operating in different parts of Finland. They have a total of approximately 300 members. The teams are mainly positioned according to the current regional borders. The teams independently study the reasons for road accidents and make proposals to improve safety. The investigation team members are subject to public liability and a non-disclosure obligation.
