The department handles all procedures relating to technical and content-related matters from the moment a warning is issued on site or a speeding violation is committed. All legal activities are concentrated there, from hearings on penalty notices or cost notices to the setting of payment facilities and the enforcement of warning fines and penalties. The monitoring and removal of unregistered vehicles, car wrecks, and bicycle wrecks, as well as the reimbursement of costs incurred in this context, are also tasks of this department.
