Mr. Drew Harris:

I think the route for this is also ANPR and static cameras, which will provide a constant read of vehicles exiting and entering a motorway.

I can give examples by taking information from other jurisdictions on cases involving suspicious vehicles. There is a need to have the correct software and for an office that can analyse the data. It is not always possible to know the plate number. All that might be known is a description of the vehicle, such as the car being a black Ford Focus. The system needs to be able to look for a black Ford Focus moving on the motorway at the time.
