    These two Functions collect vehicle identities and check to see if a violation has occurred. The two Functions are linked by a single Data Flow and also have single Data Flows that enable them to read data from Stores. Several Data Flows are provided for the exchange of data with other Areas. The Functions and Data Flows are contained in the DFD for Function 7.1 - DFD 7.1.
